THE PATH TO A SUSTAINABLE
FUTURE:
SOME POSITIVE THOUGHTS*
SUMMARY
The Brundtland Commission described the
concept of sustainable development in 1987; however, in the intervening decade some of its
basic underpinning philosophy has been lost. It is helpful to understand that limitations
to sustainable development are not hard and fast, but dynamic. Something that may appear
as a tremendous problem today may become less of an obstacle as technology and social
attitudes evolve.
Many would argue that greater economic
development fuelled by free trade is needed to alleviate human poverty and the
environmental problems it causes; yet economic development itself is a major cause of
environmental deterioration. To some, the prospect of a sustainable future appears
impossible in view of the population explosion, resource depletion, apparent limits to
food production, and global environmental crises such as climate change.
An ever-escalating world population is
obviously not sustainable; however, demographers now project that world population will
reach a state of equilibrium. Due to the phenomenal acceptance and success of birth
control technologies. Population scientists agree that world population should stabilize
at about 12.4 billion in 2035 or 14 billion people in 2100. Many have concluded that a
world population of around 14 billion may indeed be sustainable. There is good evidence
that expanded and improved agricultural production should be able to feed a world
population 2.3 times greater than todays, although this will be challenging.
Similarly, international co-operation and a commitment to good management could help
ensure the sustainable production of renewable resources. Fossil fuels will become
depleted; however, higher energy prices should encourage the development of cleaner
sources of renewable energy. Environmental concerns, such as climate change, are real but
tend to be overstated.
As the Brundtland Commission asserted, the
possibility exists for a new era of economic growth based on policies that sustain and
expand the environmental resource base; however, world-wide poverty must first be
alleviated. One engine for such outcomes is free trade. As subsidies and import duties and
quotas are removed, countries will gain the ability to succeed in those economic areas
where they have a comparative advantage. Environmentalism is an evolving phenomenon; as
the standard of living rises, there appears to be a natural public demand for improved
environmental quality. Moreover, economic development should provide the means with which
to pursue environmental objectives.
As the countries of the Western Hemisphere
come together to consider a Free Trade Area of the Americas, it is clear that their goal
is not limited to economic considerations, but rather to a future that is economically,
socially and environmentally sustainable. In the Declaration of Santa Cruz de la Sierra,
the countries of the Americas have charted a course toward sustainable development. They
have affirmed their commitments to adopt an equitable, non-discriminatory multilateral
trade system, address poverty, promote strategies to address the needs of the most
vulnerable segments of society, protect the environment, and strengthen scientific and
technological capacities.
INTRODUCTION
As the 20th century draws to a close,
there is a growing consensus that human poverty poses the single greatest threat to the
global environment. It is also increasingly understood that any attempt to deal with
global environmental problems will be largely futile unless the broader perspective of
world poverty and inequity is dealt with first. Our Common Future, the 1987 report
of The World Commission on Environment and Development (the Brundtland Commission),
addressed this grave issue in a positive manner, asserting that people can build a more
prosperous, more just, and more secure future without serious detriment to the environment
or depletion of the resource base. In lieu of a world of ever-decreasing resources,
greater pollution and mounting human misery, the Commission viewed the possibility for a
new era of economic growth based on policies that sustain and expand the environmental
resource base. The Commissioners acknowledged "such growth to be absolutely essential
to relieve the great poverty that is deepening in much of the developing world," and
they identified trade liberalization as an essential first step towards this goal.
The prospect of an expanded world economy
fuelled by free trade raises an environmental conundrum. Ever since the publication of
Rachel Carsons Silent Spring 35 years ago, it has been accepted that
economic development is the despoiler of nature. Industrial activity, resource development
and agricultural production have all been implicated as the cause of an array of
environmental ills: ozone depletion; global warming; air, water and land pollution; soil
erosion; desertification; species loss; and the depletion of limited non-renewable natural
resources. Accordingly, the question arises of how greater economic development, rather
than less, can be the answer to the planets ills. This paper examines this perceived
contradiction and challenges a number of the environmental beliefs and attitudes that
stand as impediments to the achievement of sustainable development. In addition, the trade
and sustainable development nexus is examined in the context of a Free Trade Area of the
Americas.
SUSTAINABLE DEVELOPMENT
A. Concepts and
Principles
The Brundtland Commission stated that
"sustainable development is development that meets the needs of the present without
compromising the ability of future generations to meet their own goals." The
Commission also identified two key principles as forming the conceptual underpinnings of
sustainable development. First, in endeavouring to meet essential needs, priority must be
given to development that raises the living standard of the worlds poor; and second,
limitations to sustainable development are not hard and fast, but dynamic. Limitations in
effect today may dissolve as the state of technology evolves and as social organization
adjusts.
The knowledge base is increasing
exponentially and history reports exceptionally few instances where new technologies are
not better, cleaner, faster, and more efficient than those they replace. Perhaps even more
important to the worlds poor is the fact that knowledge can now be more easily
distributed and shared than ever before. As knowledge evolves, answers will likely appear
to previously unasked questions or in response to previously unrecognized needs. More
often, however, necessity is the mother of invention. A dwindling resource commodity may
result in price escalation and the possible demise of an industrial process. This
situation encourages research and development, which may lead to the use of alternatives
or the implementation of an entirely new manufacturing process that produces a similar or
better product. Similarly, as fossil fuels become limited, financial incentives will
encourage the development of new energy sources. It is, therefore, unlikely that a
sustainable future will be limited by our current reliance on specific resources; human
ingenuity and an ever increasing wealth of knowledge should open new avenues.
The Brundtland Commission also underlined
the fact that sustainable development must involve a progressive transformation of economy
and society. Sustainable development is unlikely to continue to evolve within the confines
of rigid social and political structures; human development is dependent upon a parallel
social-political evolution that maintains equitable access to resources and to the
benefits accruing from their development. Even more critical is the environment in which
attempts are first made to nurture a sustainable future; equitable human development
cannot flourish under social-political conditions that promote or sustain the
marginalization of vulnerable groups. Sustainable development requires equitable benefits
generated from the development of a resource be made available to all members of society.
These benefits may be direct, in the form of employment, or may result from the wise
investment of generated wealth in infrastructure such as education, health care, research,
roads, communications, energy generation and transmission, housing, water supply and waste
treatment. In this manner even the poorest segments of society can benefit, the standard
and quality of life can be raised and, with time, a healthier, better educated population
can be developed that is capable of generating even greater wealth.
B.
Intergenerational Equity
Probably no concept related to sustainable
development is more poorly understood than intergenerational equity; this misunderstanding
is one of the greatest obstacles to a sustainable future. Many individuals in the
developed countries of the world view pre-industrial society as a happier, cleaner, less
stressful time, when human society existed in harmony with nature. Some people believe
that the current pace of economic development and the quest for material goods is causing
irreversible harm to the planet in the form of resource depletion, pollution, the ozone
hole, and global warming. Flowing from this sense of impending doom, a culture of
environmental advocacy has developed which promotes lifestyles dissociated from
consumerism.
This culture was given its greatest
audience at the 1992 Earth Summit, when the consumption habits of the developed countries
of the North were castigated as the prime cause of environmental deterioration world-wide.
It was suggested that the ecological carrying capacity of the globe would simply collapse
should the poor people of the South ever achieve the level of economic development and
consumerism enjoyed in the North. This opinion, however, stands in direct opposition to
that advanced by the Brundtland Commission, which viewed increased economic growth as
absolutely essential for the relief of poverty in the developing world.
The Commission called for equity within
each generation and equity between generations. Groups opposed to expanded economic
development have taken this to mean that each generation must live lightly upon the
planet, using only what is absolutely necessary to meet present needs and leaving the
planet to the next generation virtually unchanged. It is said that intergenerational
equity bestows resource rights on the unborn of future generations; that is, future
generations have as much a right as ourselves to the natural resources of the planet. Thus
the present generation has the obligation to conserve or even ration the known reserves of
non-renewable resources so that future generations will not go without.
This concept, however, presumes that the
needs of future generations will be the same as ours today. Imagine that this view of
intergenerational equity had been practised 150 years ago; our Canadian ancestors would
have conserved copper for telegraph wires, old-growth white pine forests to furnish masts
for our sailing ships, and coal-oil for our lighting needs. As impossible as it would have
been for our ancestors to anticipate our actual needs, the exponential rate of
technological advance makes it even more difficult for us to foresee the needs of our
descendants.
Many would argue that it is not reasonable
either to ration or to squander natural resources; rather, it should be the responsibility
of each generation to conduct its development in a way that does not cause long-term
damage to the natural environment. Similarly, each generation should ensure that some of
the wealth generated by the development of natural capital is wisely invested in man-made
capital that will improve the quality of life of future generations. By investing in
knowledge and societal infrastructure today, we are ensuring in the most comprehensive
manner that the needs of tomorrow can be met.
CHALLENGING ENVIRONMENTAL ASSERTIONS
Virtually every major environmental
conference over the past ten years and certainly the 1992 Earth Summit and the 1997
five-year follow-up meeting, were billed as our "last chance to save the
planet." It has been argued that the assertions of environmental groups are often
overstated and that the planet is much more in need of good management than it is of
saving.
There are two environmental beliefs which,
if true, would make the pursuit of sustainable development futile or at the least very
difficult. These are that world population is exploding at an uncontrollable rate, and
that the fragile ecological carrying capacity of the planet is on the verge of collapse
because of the irreversible depletion of finite natural resources and the overburdening of
the biosphere by toxic wastes. Such assertions have had the beneficial effect of promoting
environmental awareness among the general public and of encouraging policy makers to
institute programs and regulations to protect and conserve the environment. Data collected
by the World Health Organization, the World Bank and the United Nations, however, show
that, world-wide, child mortality rates have fallen, life expectancy has risen and that
the basic needs of food, shelter, and clothing are better met around the globe today than
ever before. We have evidence of local and regional collapse of some environmental
systems, but this does not necessarily mean that the global biosphere is in jeopardy.
These observations mean that we need to better manage and husband our environment;
specific areas of concern must be addressed, but there is definitely hope for the future.
A. The
Population Explosion
For thousands of years, the worlds
population grew at a snails pace. It took over one million years to reach the one
billion mark in the early 1800s; however, after that point, human numbers began to
increase rapidly, so that there are now an estimated six billion people on the planet. The
growth in human numbers was most rapid in the decade and a half after the Second World
War, a time when a high birth rate coincided with a decreasing death rate as a result of
improved health conditions. After 1960, however, the rate of population increase began to
slow, and today it is showing dramatic decreases.
There are many reasons why fertility
levels are dropping world-wide, but the major one has been the development of birth
control technologies, which allowed many developing countries to implement strong family
planning polices. From 1960 to 1990, the number of couples using some form of birth
control grew from 50 to 400 million. By the mid-1990s, 51% and 70% of women of
child-bearing age, in developing and developed countries respectively, were using a birth
control device. Demographers expect that by the year 2000 the birth rate in virtually all
industrialized Northern countries will have dropped to near or to below the level required
to maintain population equilibrium. In Southern countries there tends to be a wider
variation in the rate of decrease in fertility; however, it is expected that the world
population will stabilize at some point between the years 2035 to 2100. Population
projections by both the World Bank and by the United Nations concur that the world
population will reach equilibrium at 12.4 to 14 billion people, depending upon whether
stabilization is reached in 2035 or 2100. The question that now arises is whether the
earths ecosystem can provide sufficient resources to support a stable population
that would be more than twice that of today.
B. Agriculture
Many environmentalists contend that we
have maximized the amount of land that can be devoted to agriculture and that agricultural
practices and technologies have advanced to their natural limit. Agronomists, on the other
hand, are confident that the agricultural resources of the world can be developed further,
to meet the nutritional demands of 14 billion people.
At the beginning of this century, both
Canada and the United States had largely agrarian economies characterized by
low-technology agricultural practices. Between 1910 and 1990, though the amount of land in
the United States devoted to agriculture declined slightly from 325 to 322 million acres,
agricultural production increased 370%. A similar situation has come about in Canada, with
millions of acres of marginal farmland allowed to revert to forest. During the past
quarter century, world food production has doubled; 90% of this increase is due to the
increased productivity of existing farmland, and only 10% to increased farm acreage.
Just as farm productivity has increased in
developed countries, there should be enormous increases in productivity in developing
countries as high-yield agriculture practices, commercial fertilizers, improved crop
varieties and efficient irrigation systems become more common there. Of particular
importance is the transfer of improved irrigation technologies. The systems in use in much
of the world are highly inefficient, wasting huge amounts of fresh water that could be
used to support wildlife, fish stocks, or manufacturing activities. Worse, excessive
irrigation results in salinization of the soil and the long-term loss of productive
agricultural land.
Food productivity may also be increased
through the cultivation of at present unused or underutilized arable land. Approximately
24% of the total ice-free landmass is suitable for agricultural production, yet less than
50% of this area is cultivated in any given year. It should also be noted that extremely
high yields of some vegetables (tomatoes, lettuce, cucumbers, peppers and beans) are
achieved by greenhouse cultivation and by hydroponic gardening.
Some suggest that intensive modern
agricultural practices are reducing soil fertility and causing erosion. Although, this
view is not completely shared by all agronomists, there is little doubt that the
restoration of soil fertility will become an increasingly important area of research. It
must also be recognized that, while the earth may be capable of producing enough food to
meet the needs of 14 billion people, droughts or inefficient food distribution systems
could place millions at risk of famine. Also, the poorest inhabitants of the world may
have trouble in affording local produce, let alone hydroponically grown tomatoes from
Europe. For many nations of the world, the only answer to the threat of hunger may be the
adoption of sustainable agricultural practices and a strong national commitment to family
planning.
C. Natural
Resource Depletion
Any renewable natural resource, such as
forests or fisheries, should be perpetually sustainable under good management; the
prospects for this are frequently improved when property rights are applied to a renewable
stock. While abuse of the commons is destroying rain forests, devastating fisheries and
threatening biodiversity, there can be a different outcome where resources are owned. For
example, many Canadians in Newfoundland find themselves unemployed because of the collapse
of the cod fishery yet, at the same time, fish farms in Chile, Norway, Southeast Asia,
Japan and Great Britain are increasingly supplying the world seafood markets. It should be
noted, however, that the private ownership of renewable resources does not inevitably
result in good management; history is rife with examples of poor decision-making and the
destruction of a local resource for short-term gain. Also, mismanagement of fish and
shrimp farms can cause significant pollution and many would argue that fish farms are not
a good alternative to a well-managed traditional fishery. International co-operation in
the form of international agreements to conserve shared resources (for example, straddling
fish stocks) are essential if the abuse of the commons is to end.
The time needed to convert organic matter
into coal, oil and gas is too great for fossil fuel to be considered as a renewable
resource and, of all the resources it is the only one that may actually become depleted.
According to United States Geological Survey Data, there are enough recoverable fossil
fuels to last just over 500 years at projected rates of demand. This is not as rosy a
projection as it may appear, for the reserves of cleaner-burning oil and gas would be
depleted long before the less desirable coal reserves were fully exploited. As these
reserves become limited, costs will likely increase and the alternative sources of
renewable energy should become competitive. Solar, wind and bioenergy research, which
received a great deal of development funding following the oil crisis of the 1970s, would
likely be revived, and there could possibly be a re-examination of nuclear power to
determine novel means for making it safer. Future depletion of fossil fuel has already
encouraged a number of nations, particularly Japan, to investigate the possibility of
exploiting the large deep sea reserves of methyl hydrate as a replacement for current
sources of natural gas. Also, research would likely be encouraged in areas of energy
conservation such as more efficient energy transmission, and the development of a second
generation of energy-efficient manufacturing processes, machinery, engines, motors and
appliances. Sceptics may suggest we have reached the zenith of our technological abilities
to produce, store and use energy, but there is no reason to believe this. Just as our
ancestors of 100 years ago had absolutely no comprehension of thermonuclear power, so we
should not dismiss the possibility that the world in the year 2100 could not be powered by
an energy source of which we are currently unaware.
A reasonable means of determining whether
a resource is in short supply is to analyze commodity price data. A review of the prices
of food, lumber, paper, minerals and energy relative to buying power over the period of
1950 to 1990 (Table 1) shows that resources have become less expensive. An oil
embargo or the desperate sell-off of a commodity to fund debt payments can disrupt markets
and in the short term distort the picture of supply and demand. The 40-year picture
provided by Table 1 does reveal short-term fluctuations; however, since the overall
trend is towards greater buying power, none of these commodities can probably be
considered to be scarce.

Proven reserves measure the amount
of a given resource that has been discovered and can be extracted profitably, given
current prices and state of technology. Table 2 shows that, with the exception of
tin, the proven reserves for a variety of non-renewable resources have increased, not
decreased, over the past 40 years. Iron, aluminum, bauxite, silicon, magnesium,
titanium, copper, zinc, manganese, chromium, lead, nickel and tin make up most of the
worlds demand for industrial minerals. For time to time, fluctuations in supply and
demand may make it appear that a mineral is in limited supply. When this occurs, higher
prices encourage exploration and make it worthwhile to mine reserves that were previously
not considered profitable. Similarly, advances in mining technology allow the exploitation
of mineral reserves that were previously considered of marginal value or to have been
"mined out." Low supply and high cost also work to encourage changes in market
demand. For example, higher tin prices give aluminum packaging a market advantage. At
present, no inorganic mineral has been identified as being exhaustible; indeed, the
mineral wealth of the earths mantle remains virtually untapped. The question,
therefore, is not whether a mineral is exhaustible, but whether its economic value
justifies its extraction.

The language of
environmentalism is emotive; it is hard to reconcile terms such as mineral exploitation
and depletion with the assertion that most non-renewable resources are probably
inexhaustible. Our biosphere is a closed system; gold mined 2,000 years ago is still with
us. A vein of iron ore may become depleted, but this does not mean the steel it produced
cannot be recycled into another car part or a bridge girder. Once a mineral is mined, its
availability to future generations actually increases for much of it may be recycled in
perpetuity at a reduced cost, since the cost of extracting and processing a virgin mineral
is more than the cost of recycling it, both in terms of money and pollution. Not all
excavated minerals have been recycled of course; some will remain in use for generations,
some may become oxidized, some low concentrations may be dispersed in the environment as a
result of automotive and industrial activities, and some will be "discarded" in
landfills. "Stored" in landfills is perhaps a better phrase, however, as the
mining of landfill sites is now considered a cost effective means of reclaiming valuable
minerals.
D.
Global Environmental Crises
One of the principal arguments against
sustainable development is that the biosphere could never absorb and neutralize the waste
products and pollution that would result from raising the entire population of the world
out of poverty. The most immediate example cited is global warming; however, this is also
an example of how environmental concerns may be selectively overstated.
The greenhouse theory and the possibility
of global warming were introduced in the scientific literature over 100 years ago, but it
was not until the 1980s that public concern was generated. According to the media reports
of the time, general climate models developed by atmospheric scientists showed that the
accumulation of carbon dioxide and other greenhouse gases in the atmosphere would cause
the global mean temperature to rise by as much as 4.5oC. This warming would
cause the ice caps to melt, flooding coastal cities and island nations. As well, rainfall
patterns would change, deluging coastal regions and eroding soils; dry grassland regions
would become unproductive deserts. Further extrapolations predicted imminent mass famine,
disease and the unprecedented migration of eco-refugees.
A decade later, not one of these model
predictions has come about. The research scientists who published the papers had made no
secret of the fact the models were primitive; because of limited computing power, only
greenhouse gases had been included in their model calculations and those factors that
would serve to cool the planet had been ignored. The problem was overstated because of how
non-scientists interpreted science.
Over the ages, the earth has been both
considerably hotter and colder than it is today, making it difficult to ascertain what
global mean temperature is optimum for life on the planet. This point is becoming
increasingly apparent as more research is conducted on climate change. In 1995, the
Intergovernmental Panel on Climate Change published its now famous consensus statement
that "... the balance of evidence suggests that there is a discernible human
influence on global climate." This "human fingerprint" was identified as an
increase in the average minimum night-time temperature; however, no increase in maximum
day-time temperature has been observed. These facts have tremendous positive implications
for world agriculture and an expanding population because they suggest more frost-free
days and a longer growing season. During the last two years there has been a substantial
increase in the number of scientific publications suggesting that warming may provide some
benefits. It is of considerable significance that the vast majority of plant species
tested under conditions of carbon dioxide enrichment exhibit an increased rate of
photosynthesis, greater biomass and improved harvestable yield. Models also predict that,
because of increased temperature and rainfall, most of the 57 million hectares of arable
land of the sub-arctic regions of Alaska and north-western Canada would become
climatically suitable for agriculture.
This is not to suggest that climate change
will provide only benefits; indeed, it should be expected that there will be both positive
and negative consequences. What is important in the context of sustainable development is
that the road to a sustainable future may be complicated by many environmental concerns
that are perhaps more illusory than real. Policy makers should challenge environmental
assertions, base their evaluation of environmental concerns on solid scientific evidence,
and ensure that they weigh social, economic and environmental concerns equally when making
their decisions. Further the existence of transboundary or global environmental problems
be verified, the best solution will be for countries to participate in bilateral or
multilateral negotiations based on scientific evidence and leading to binding
international agreements.
THE EVOLUTION OF ENVIRONMENTAL
PRIORITIES
It is recognized that nothing is sadder
than families driven to such desperation that they eat their seed grain. There are
millions of families so abysmally poor that their first and virtually only concern is
having enough to eat. Environmental quality is an unrecognized concern for people living
at a subsistence level; this situation could continue even when the basic needs of food,
shelter and clothing are met, as other needs, such as education and health care, become
the new priorities.
In the very poor countries of the world
the two greatest environmental health risks are infectious diseases from the consumption
of drinking water contaminated with human waste, and the inhalation of indoor air
pollutants from unvented home cooking equipment. Even inexpensive and low-technology
remedies are often beyond the means of the poorest communities; however, when economic
growth begins, these are the first problems to be rectified.
The links between per capita income and a
public desire for environmental protection have been well studied. As societies
industrialize and incomes begin to rise there is actually a decrease in the environmental
health of the region. This is because domestic industries generally begin development at a
low technological level with no pollution control devices and with the public priority for
jobs, not environmental quality. Industrial air, water and land pollution usually
continues until per capita income reaches $4,000 (U.S.). World Health Organization data
from pollution studies in developing industrializing countries showed that particulate and
sulphur dioxide emissions declined when per capita income exceeded $5,000 and declined
dramatically as income approached that of developed Northern countries. Similarly,
analyses conducted by the World Bank demonstrated that most concentrations of air, water
and land pollutants decline as per capita income rises. A United Nations study on urban
air pollution in megacities found that economic development reduced the concentration of
atmospheric pollutants and was vital in bringing urban areas into compliance with air
quality standards.
Once a country has achieved some
industrial success in the form of increases in GNP and per capita income, a number of
factors join to promote environmental protection and conservation. Wealthier people have
more leisure time to enjoy activities that involve the natural environment. They increase
their expenditures on recreational activities and will bid land and resources away from
other uses. In democratic societies, as public intolerance to pollution grows, political
pressure is applied for the enactment and enforcement of environmental regulations. As
industries acquire wealth they are not only more able to meet public environmental
expectations, they may also go beyond established guidelines and standards in anticipation
of more stringent regulations or to promote better public relations.
To a very large extent, improvements in
environmental protection and conservation are directly linked to the evolving wealth of
nations. As a result, the well-intentioned efforts of environmentalists to encourage
action in developing countries may be futile, since the priorities of environmentalists
and the desperately poor of the world may not be the same. The Brundtland Commission
stated: "poverty is a major cause and effect of global environmental problems."
Before such issues as biodiversity protection and pollution abatement are tackled, we must
start the natural evolution of environmentalism through the alleviation of poverty.
TRADE
AND SUSTAINABLE DEVELOPMENT
Since the publication of Our Common
Future, there has been increasing recognition that economic development and
environmental protection are inextricably linked; a synergism that will be accelerated
through free trade among nations. At the 1992 Earth Summit, the links between trade and
the environment were well analyzed; problems were identified and a variety of possible
solutions suggested. High among the list of problems were the use of subsidies and the
imposition of trade barriers to promote and to protect domestic markets. In many cases,
subsidization of an activity has a negative social or environmental consequence. For
example, when electrical costs are subsidized, the public attaches a lower value to this
energy source; the result is waste, greater demand, the consequent need for additional
generating capacity, and increased energy-related pollutants. Electrical subsidies also
discourage investment in new, cleaner industrial technologies. Similar problems arise with
subsidies to irrigation water, fossil fuels, forest or fish resources, fertilizer or farm
equipment.
Trade barriers may also have negative
consequences both at home and in other countries. Both the Earth Summit and the Brundtland
Commission identified tariffs and subsidies as perverse incentives which encourage the
development of products that otherwise would never be profitable. The classic example is
the world sugar market. The developing countries of the tropics have the comparative
advantage for sugar production, and it is estimated that nearly 30 million people in these
countries depend upon sugar cane cultivation for their survival. Yet, at the same time,
the governments of many developed nations have placed tariffs or quotas on sugar imports
in an effort to protect their domestic sugar beet industry. Cane sugar surpluses depress
world prices and lead to lower incomes, while high prices in developed countries promote
cultivation of sugar beets on land that might be better used for other crops. Sugar beet
growing is highly capital-intensive and depends heavily on chemical herbicides. Market
protection has also had the effect of helping to promote an artificial sweetener industry,
thereby further depressing sugar markets. If world sugar requirements were met by
developing nations, the result would be lower sugar prices in developed countries, the use
of fewer chemical additives, and greater employment opportunities for some of the
worlds poorest people.
A great deal of excellent work was
accomplished at the Earth Summit; however, on occasion there was the tendency for policy
development to reflect an environmental point of view at the expense of social and
economic concerns. In particular, some trade issues may not have been evaluated completely
objectively and discussions may have failed to include some historical and present-day
development realities. In the debate on the possibility of a Free Trade Area of the
Americas, some precedents established at the Earth Summit could possibly stand as
obstacles or lead to unrealistic expectations.
The major obstacle is the attitude that
"over-consumption" in the industrialized countries of the North is the prime
cause of environmental deterioration world wide. It is precisely this material wealth and
standard of living, however, to which countries of the South aspire. Further, it is this
economic paradigm that may ultimately alleviate the poverty of nations and encourage
sustainable development. This same attitude assumes that the success of developed nations
was gained at the expense of developing nations and that therefore the Northern countries
have a moral obligation to give developing nations financial assistance and access to new
technology.
At the 1992 Earth Summit,
environmentalists concerned about global warming proposed that the developed countries of
the North transfer pollution control technology to Chinese industry. The reception given
this suggestion was lukewarm. It was recognized that, while a relatively poor country,
China is not technologically backward; rather, it may give other preoccupations, such as
defence, priority status. While there is no question that Chinese industry is a
significant source of air pollution, the principal cause of environmental health problems
in China is indoor air quality. More than 75% of Chinas primary energy needs are
supplied by domestic coal, and much of Chinas population cooks and heats by using
unvented stoves fuelled by coal or biomass. As China has modernized, deaths from
malnutrition and infectious diseases have plummeted, while diseases linked to air
pollution have spiralled to become the countrys number one public health threat. Air
pollution accounts for more than 1 million deaths per year, or about one in every
eight deaths. It has been argued that, from a social, economic and environmental point of
view, it might have been better for environmentalists to suggest that the countries of the
North liberalize trading relations with China, thereby raising domestic income and thus
assisting the Chinese people in addressing their environmental health problems.
There are certainly specific examples of
how the economic policy of a developed country has had a negative effect on a developing
country; however, it is very unlikely that this was the sole reason for a countrys
failure to thrive. There are many reasons for such failure. For example, two neighbouring
countries with similar natural wealth but divergent economic philosophies could be
expected to have significantly different levels of national wealth after half a century of
development.
Paramount in the achievement of countries
that have enjoyed economic, social and environmental success, have been land tenure and
equal opportunity for citizens. With property rights come self interest and the
responsibility to manage that land and its resources sustainably. Countries often fail to
prosper because of such impediments to economic growth as government mismanagement of the
economy, debt, corruption, political instability, over-valued exchange rates, isolationist
policies; prohibitions against foreign business operations, or a history of nationalizing
foreign-owned industry. As countries consider the possibility of free trade, it is
important that they evaluate their economic history, identify the reasons for past
failures, and from there chart an action plan for sustainable development.
FREE TRADE IN
THE AMERICAS
As the countries of the Western Hemisphere
come together in consideration of a Free Trade Area of the Americas it should be
increasingly apparent that sustainable development is not only desirable but achievable,
and should be facilitated by free trade.
The countries of the Americas vary widely
in their natural and cultural diversity, political tradition, and level of economic
development. As our countries enter into free trade agreements, it could be argued that it
would be unreasonable to expect the lesser developed countries immediately to adopt the
same rigorous environmental regulations as more developed countries. Environmentalism is
an evolving phenomenon; as the standard of living rises, so does public demand for
improved environmental quality. Moreover, economic development could provide these
countries with the means to pursue their environmental objectives. Through the exchange of
environmental information, national experience, and recommendations, developing countries
should be able to improve their environmental standards more rapidly, so that eventually
similar levels of environmental protection and conservation should prevail throughout the
Western Hemisphere. The already established United Nations Commission on Sustainable
Development is an essential institution for promoting information sharing and developing
political will towards this end.
During negotiations for the North American
Free Trade Agreement (NAFTA), opponents contended that differences in environmental
regulations would give countries with less stringent legislation an economic advantage.
Further, it was suggested that countries would have to lower their own environmental
standards in order to stop polluting industries from moving to "pollution
havens." This has not been the Canadian experience. Indeed during the last decade,
only one polluting industry has closed its doors in Canada because of stringent
environmental regulations; it moved, not to Mexico, but to the United States. Further,
since the ratification of NAFTA, Canada has consistently worked toward strengthening its
environmental legislation, and has enacted what are perhaps the most stringent regulations
in the world to control water pollution from pulp and paper mills.
As countries participate more openly in
free trade, subsidies and trade quotas will gradually disappear and each country will be
able to succeed in those areas where it has a comparative advantage. Of particular
importance to developing countries, sustainable development will be encouraged through
national policies that encourage foreign investment, often the quickest route to the
acquisition of new technologies and pollution abatement equipment. Even when national
legislation does not require modern pollution controls, a foreign company is likely to
incorporate state-of-the-art environmental technology during the construction phase,
partly because the technology is already part of the design process, and partly because it
is much less inexpensive to include this technology during the building phase than to add
it at a later date when the host country has raised its environmental standards.
In the Declaration of Santa Cruz de la
Sierra, the countries of the Americas have charted a well defined course toward
sustainable development. They have affirmed their commitment to promote human dignity and
their respect for cultural diversity; and have agreed, as a primary objective, to
implement relevant measures for meeting the basic needs of the most vulnerable segments of
society. These basic needs include: equitable access to adequate nutrition, health care,
clean drinking water, employment, and housing. The declaration attests to the
countries strong commitment to promote healthy environments. Nations will assess the
environmental impacts of their policies, strategies, programs and projects both nationally
and in the framework of international agreements to ensure that adverse environmental
effects are identified and prevented, minimized, or mitigated. Nations will strengthen
their scientific and technological capacities and will promote the sharing of scientific
and technological advancements. These, and other goals, will be achieved by adopting an
open, equitable, and non-discriminatory multilateral trade system based on the principles
of international law and sensitive to the evolving needs of sustainable societies.
