Economics and Ecology

          There are two diametrically opposite sides to the great debate between protecting the environment versus allowing for increased economic growth and prosperity regardless of ecological impacts upon our environment.  Many claim that maximizing profit while minimizing ecological damage is politically and structurally impossible.  On one side, there are economists insisting that it is too costly to impose policies that limit or prohibit pollution.  They claim that reducing pollution cuts firms’ profits, resulting in a lessening of the nation’s overall output.  On the other end of the spectrum are the environmentalists who claim that harming the environment through the emissions of pollutants and widespread habitat destruction decreases productivity in the long run.  The latter argument relies on the assertion that increasing productivity year after year—as economists would like to see happen—would actually only decrease productivity in the long run as resources are depleted.  Exploring the relationship between developed and developing countries allows us to see where the greatest problems lie.  From this relationship, we can better determine the policy actions that need to be implemented worldwide in order to satisfy both sides of the environmental/economic divide.

 

State of the Economies of the World

          While the economies of the countries of the world are seeing monetary growth overall, their environmental welfare is rapidly decreasing.  From 1965 to 1980, middle income countries such as Chile and Argentina experienced GDP growth at an annual rate of about 6.1%, while low-income countries such as India and China saw an average growth of 5.4%.  High-income countries experienced an average of 3.7% growth (World Development Report, 1993).  From 1980 to 1991, however, middle-income and high income countries dropped off to 2.1% and 2.9% respectively while low-income countries increased growth to 5.9%.  Viewed as a positive increase for these lesser developed countries, the externalities that are a byproduct of this growth are ignored.

          Economic growth at low levels of technology tends to be heavily reliant upon natural resources. Much of the environmental destruction in developing countries is facilitated by the interference (whether well intentioned or profit-motivated) of developed countries. In certain cases, developed countries act as mentors to help facilitate positive growth in impoverished and infrastructure-weak countries.  In others, profit seekers contribute to the problem by establishing manufacturing hubs in countries where labor is cheap, environmental protection laws are nearly non-existent, and resistance to industrialization is low. Worldwide, the total of cultivated land is estimated to have increased 466% over the past two centuries—the result of mass forest clearing and destruction of habitats.  Much of this destruction is occurring in developing countries, yet they see little of the economic benefits but experience all of the environmental costs.

 

The “Inverted-U” Relationship

Many economists assert that there is an inverted U-shaped relationship between measures of environmental quality and per capita income.  As income goes up they observe increasing environmental degradation to a point, after which there is a reversal of the trend and environmental quality improves thereafter (Arrow et al., 1995).  On the surface it makes sense to say, therefore, that as developing countries progress further and further along the path of development the state of the environment will eventually improve from the dire conditions that many environmentalists decry so vehemently (Grossman and Krueger, 1995).  However, this U-shaped relationship holds for only short-term effects without considering the longer run.  Additionally, the U-shaped curve applies only to certain pollutants and not to many non-renewable resources. 

It is these non-renewable resources that form the earth’s resource base that we rely upon.  While there is evidence that supports the idea that increased economic growth may be associated with increased attention to environmental protection, there is also evidence which refutes any claim that the Earth’s resource base is capable of supporting economic growth indefinitely .

In the event that non-renewable resources are not consumed completely, they become more costly to use each time one additional unit is consumed since each unit consumed lowers remaining available supply; increasing marginal costs of future use.   Even in a best case scenario where all other costs remain constant and demand is constant, the marginal costs raise overall price to the consumer. This price increase continues on in perpetuity until the resource is exhausted or demand for it decreases enough to allow it to regenerate at the rate nature allows. 

In a comparison between developing and already developed countries, developed countries are recognized as the more energy efficient of the two (Duraiappah, 1998).  This means that statistically speaking, every year developed countries are responsible for the least amount (measured in percentage share per country) of pollution emissions due to relatively clean technologies and (for a rising number of them) environmental policy regulation. 

However, every one of these countries was once underdeveloped.  So at one point, each emitted huge amounts of carbon, deforested at rates surpassing those of natural regeneration, and otherwise abused their environment wantonly.  Though it may be said that these countries are protecting their environments now, it is more accurate to say that they are protecting what is left of their environments after such large-scale destruction in the past.  Therefor, with regard to the developing countries, they are approaching the maximum point of their inverted “U” of development.  In other words, they are almost at the bottom point with respect to the state of their environment.  Soon, many rain forests and other natural non-renewable resources will be transformed into agricultural land and cities.  Once lost, these whole ecosystems cannot be replanted like a Christmas tree farm.  From newly extinct species to global warming, the effects will be spread far and wide across the globe. 

         

Paths of Development

          Both environmentally destructive behavior and intense population growth in these countries can be attributed mainly to low levels of technology.  With less technology, more manpower is needed for the same amount of output, resulting in demand for larger families.  In addition, little technological know-how leads to less efficient production and more waste.  With this in mind, many economists argue that developed countries are the least responsible for the environment’s problems worldwide since as economies improve along with technology, population growth tends to decrease (less labor-intensive work lessens demand for large families) and reliance on natural resources decreases (Duraiappah, 1998). 

Though true in many respects, this assertion does not hold in the sense that it is the developed countries that are forging the paths for others to follow. If one looks at current environmental trends in developing countries, it is clear that destructive behavior is ongoing. One well-documented example of this behavior is deforestation.  Rates of deforestation may not be the same as they were years ago, in fact they have reduced, but the same practices are being used to gross profit from the vast natural resources available to the people of these regions.  While developed countries introduce programs to regulate the deforestation of these developing regions, many of their inhabitants may argue that their livelihood is more important than any regulation brought before them.  While this may be difficult to comprehend from the ‘developed country citizen’ point of view, one can take a step back in history to see why these inhabitants feel they must practice environmentally destructive behavior.

          The original European settlers of the United States did to North America what is now being done in developing countries.  In one lifetime, approximately 85% of the primary, old-growth forest of the U.S. were destroyed.  That 85% is approximately the size of Europe itself.  (Mackenzie, 1998)  European settlers had no other way to amass capital than to take it from their natural resources, and inhabitants of developing countries are in the same predicament.  Following the path that was taken centuries ago by now developed countries, they are emulating an old formula for “development” that will bring the earth to environmental ruin.

          Upon obtaining independence, most developing countries have traditionally followed a model for development that is centered around one goal, transition from a backward agrarian economy to an industrial one. Industrially developed countries boast of better health care, security, infant mortality rates, etc, etc, - essentially a better “standard of living.”  Understandably, developing countries set this as their goal yet they take an oblique approach.  They follow an outdated model.  This model can be characterized by the attitude of the ruling government towards four main issues: physical capital, agriculture, trade, and the market.  For the purpose of this paper, only the first two issues will be discussed as it is they that most relate to environmental degradation and its link to economics.     

                The traditional model of development suggests that a developing country amass physical capital as rapidly as possible.  Methods of amassing capital include exploiting available resources or saving and investing what little money is available.  The intent is to give a country the resources needed to begin its process of building the infrastructure necessary to embark upon industrialization.  While this may sound positive, it is almost impossible to do when starting with the conditions that developing countries face.  They simply cannot save or invest what little money they have.  Thus they resort to exploiting their resources - resulting in environmental disaster. 

          Further clarifying the traditional model of development, government planners take a negative stance on agriculture.  They structure policies that protect industry and turn the terms of trade against agriculture.  In a race with other developing countries, government planners take any step they deem necessary to promote the growth of industry within their borders.   

Again, this is a problem for several reasons.  Some of the cultures within these borders are agrarian in their nature.  Taking a people from their way of life becomes yet another issue government planners must confront.  Even more importantly regarding the issue of industrialization, government planners often fail to realize the full economic potential of agriculture.  With the right planning and investment in technology, agriculture can be extremely profitable – even more so than countless industries. 

          In summary, developing countries tried to arrive at an industrial state by sticking to four beliefs they thought were necessary: a rapid accumulation of capital, policies promoting industry over agriculture, a response to import protection and state controlled markets (Schulz, 1983).  While many developing countries still follow this doctrine, it is clear that it isn’t the best possible one given today’s conditions.  Current economists tout an updated plan that boasts of the following:  physical capital accumulation in the terms of investing in education and training for citizens of a developing nation, the promotion of agricultural enterprises that have a promise of growth and profitability, trade outside of national borders and a reliability on the market as the dominating factor in making financial decisions.  While this plan may be better than the old, it cannot be given the dominating importance that the old one was.

          Repeatedly, developing countries have tried to “develop” by following the steps of the developed.  Repeatedly, they have failed.  A reliability on outside thought appears to be a major factor in decision making.  This would be a good place to start when analyzing current situations and making future plans.  If outside ideas have taken the industrialization process no further, and have caused environmental decay, why stick to them?  Developing countries should take a close look at the history of their region and mold a new style of development that is specific to their people.

Going where none have gone before gives developed countries greater responsibility to tread carefully as they forge on forward.  By leading developing countries along an environmentally sustainable growth path, perhaps many destructive practices can be avoided in the future.

 

Environmental Policy Options

          Due to the neoteric awareness of environmental issues as related to the economy, traditional economic models have not taken the costs of environmental degradation into consideration when calculating losses from productivity under abatement policies (Barrett, 1990).  All that is taken into consideration is the cost of abatement technologies.  This leaves the benefits of a cleaner environment unaccounted for.  It is more than possible that in the long run these benefits to society will offset and even exceed the costs of implementing abatement and other environmentally friendly programs worldwide.

          Assuming that this argument is accepted by the countries of the world, how can they be environmentally responsible while maintaining growth?  In terms of what individual countries can do within their borders, environmental policies can take the form of research subsidies, emissions taxes or tradable permits (Pekelney, 1993).  Benefits for each of these policies even out though they are distributed among society differently.  Subsidies are most liked by firms because they are simply given the incentive to research new technologies without command and control mandates ordering them to make changes.  However, the money for these subsidies must come from taxpayer’s pockets.  Essentially, taxpayers pay firms not to harm them.  With emissions taxes, firms are directly held responsible for their actions.  For every additional amount of pollutants emitted above a given level under this policy, the firms must pay taxes.  So the taxpayers and government benefit under an emissions tax (unfortunately, the thought of a “tax” is not popular with voters even when the tax will be to their benefit.  Contrarily, “subsidy” does not have such a foul ring to it and voters are much more likely to agree to this even though they will be the losers with such a policy!).

          The third policy option allowing for tradable permits is the best compromise.  Firms are allotted (or must purchase through an auction) a certain number of permits, each allowing for one unit of emissions.  Once allotted, these permits are tradable among other firms.  This policy rewards firms that don’t pollute by allowing them to sell the use of their permits to firms that do pollute.  The environment and society at large benefit by being exposed to less contaminants.

 

Policy Implementation and its Discontents

          Because the biosphere is communally owned, it is imperative to involve more than just a few countries in the abatement process in order to have a significant positive effect on the environment without having to depend on just a few countries to handle the abatement load alone.  However, as many economists and non-economists alike will agree, users of a communally owned resource tend to abuse the privileges extended to them through communal ownership by overusing the resource and not taking responsibility for the consequences.  This is the problem of ‘free-riders.’ 

          A prime illustration of this free-rider “tragedy of the commons” is the situation many fisheries are currently facing (Safina, 1995).  Overfishing and pollution have taken their toll by exhausting the seas’ supply of marketable fish.  Experts now believe that the fishing limit had been reached decades ago, though the results are just beginning to become evident.  Because there is no owner of the sea, per se, fishing companies have given no thought of there being a limit on the number of fish to be caught.  As a result, wild fish have been harvested at rates that surpass their natural reproductive rates.  As the population declines, fishing does not.  Too few fish have now been left in the sea to maintain spawning stocks.  Almost all of the 200 fisheries the Food and Agricultural Organization monitor are fully exploited (Norse, 1991).  The fisheries would only need a year or two to rebuild their fish populations, but fishermen have families to feed and mortgages to pay so they cannot afford to allow the fish populations to restock.  Even if an agreement were to be reached that restricts the amount of fish harvested (which is a policy now being implemented) per fisherman, there will always be free-loaders who take advantage of this slowdown to catch more fish themselves, driving the others out of the market.  This is an example of the ecological cycle being slower than the economic cycle, and the effects of this relationship. 

          When this “tragedy of the commons” is applied to world environmental policy, the free riders are generally the lesser developed countries which actually do the majority of the damage to the environment (Barrett, 1990).  There is no world government empowered to intervene for the good of all, so poorer countries free ride since it is in their best interest to reap the benefits of an environmental policy at the economic expense of others.  When all parties cooperate, the benefits are largest for the whole, but smaller for each individual country (since they have abatement costs to contend with).  Therefore, it is in each country’s best interest to free ride as long as others do not.  Unfortunately, if everyone thinks this way, there will be inaction all around.  The most effective way to combat this free rider effect is for countries to pressure the others into compliance, withholding trading or economic assistance if they continue to free load.

 

Environmental Externalities and Productivity

          Popular thought seems to hold that productivity growth will slow with the increase of environmental protection (Reppetto, 1997).  Proponents of this belief state that the cost to implement abatement programs and restructure factories to comply with strict environmental regulations will force competitive companies under by raising costs for firms and bringing prices up for consumers.  These economists are not taking into account that there are significant costs associated with a polluted environment (Barbera and McConnell, 1990).  To measure welfare of the nation, economists generally rely on GNP statistics, equating the country’s overall welfare with economic wellbeing.  This is based on the assumption that dollars are directly correlated with welfare and that maximizing GNP therefore maximizes welfare.

          For this to be true, the dollar cost of environmental degradation must be measured and accounted for within this framework.  How does one go about putting a dollar value to blue skies, open land, and clean rivers?  What price do we pay for mass deforestation, tainted well water, and crowded cities?  Unlike typical market goods such as computers or cars, no one is willing to save up their paychecks in order to purchase a plot of clear sky.  The environment isn’t simply a good to consume at will and reengineer back into existence.  It is a complex structure that humans rely on for survival, though they may never consider it.

          A typical 500-megawatt power station fired by coal doesn’t just produce 3.5 billion kilowatt hours of electricity per year.  Also produced as a byproduct of the process are:

          “…5,000 tons of sulfur oxides, 10,000 tons of nitrogen oxides, 500 tons of particulate matter, 225 pounds of arsenic, 4.1 pounds of cadmium, and 114 pounds of lead, as well as trace amounts of other minerals embedded in the coal” (Repetto et al, 1997).

 

          Omitting these huge wastes while calculating productivity is a terrible miscalculation.  To generate 5 billion tons of market goods each year, the U.S. uses more than double that amount of crude material.  That is a waste of 5 billion tons of material each year—not to mention the nearly two billion tons lost to the environment in the form of emissions and effluents that sully land, water, and air.  Regardless, economists continue to ignore these enormous externalities when accounting for the nation’s welfare.

          Factories emitting noxious pollutants are doing a disservice to society and should be held accountable.  Since firms and individuals maximize profit in dollars, without a value given to this externality, the damage incurred slips through the cracks.  Eventually, as ecological abuse becomes more severe there comes a need for less efficient industry-supplied substitutes (often produced at great societal expense).  In essence, the pursuit of short-term economic gain (as reflected in GNP statistics) often leads to longer-term economic loss though lost production due to depleted or exhausted resources.

 

Synthesis of Economics and Ecology

          A solution to these problems can only come through the realization that the environment and the economy are intertwined aspects of a bigger picture, rather than altogether separate entities.  Thus far, this is not a conclusion that economists and ecologists have come to agreement upon.  A successful synthesis between economics and ecology has yet to be reached, though it is evident that measuring ecology and mathematics on the same mathematical scale by giving a dollar value to the costs and benefits of protecting the environment is not quite making the mark.

          With all the evidence in support of the need to incorporate ecological concerns into the overall economic framework, finding an exact way to offset environmental externalities still eludes resolution.  The reason is deceptively simple.  As seen with the example of fisheries, the ecological cycle operates much more slowly than does the economic cycle.  With the rates of natural ecosystem regeneration much slower than those of consumption, it is no great wonder that some of nature’s subsystems are threatening extinction.  The ideal solution would be to find a way to equalize the rates.  Unfortunately, the economic cycle is driven by the need to maximize profit, while the natural cycle requires only the minimum of survival (Safina, 1995).  It is unrealistic to hope the environment will adapt to the human-made economic cycle by speeding up production.  Fish will not produce more offspring simply to keep up with our demand for exotic dishes, nor will trees in forests grow faster to replace the great number that are being cut down to construct cities.

          This leaves the economic cycle the task of adaptation.  With greater concern for short-term profit over long-term wellbeing, it may be difficult to convince individuals and firms to look towards the future and accept as certainty a surmise that one day there will be nothing left if they continue on as they are.  Behind each firm there are individuals whose lifetimes will be too short to experience this predicted ruin.  Since it is not in their own interest to accept the full costs they are creating for future generations, the economy continues to run along the same path of blissful ignorance.  Thus, since the nation’s growth remains strong, economists are satisfied that high GNP is indicative of a high level of societal welfare.

 

Where Do We Go From Here?

          How long will the economy continue to grow under this system of thought?  Even though the U.S. has seen a significant improvement in the effectiveness of environmental policy thus far, we are all under a time constraint.  There is only so much population and industry growth, land use change, and world development that the earth can withstand.  As population grows, most especially in developing countries that make up four-fifths of the world, development skyrockets as the quest for a higher standard of living complete with picket fence and cocker spaniel takes hold of more and more minds.

          The common belief that humans are somehow special and separate from the rest of nature contributes to a widely accepted utilitarian view of nature.  However, because of the scale of human consumption of ‘nature’s goods’, this view cannot be supported for long.  Over the years, this disregard for the impact of human actions upon the environment has resulted in large-scale destruction of natural subsystems (Mackenzie, 1998).  As the world population grows, there is increasing demand for energy to satisfy human desires.  This results in an ever-accumulating deficit of natural resources as they are depleted much faster than humans and nature permit them to regenerate.  Land is converted from forests, swamps, and grasslands to cities, suburbs, and industrial hubs.  Roads divide, cities crowd, and human waste destroys whole ecosystems.  This environmental degradation is threatening society’s ability to sustain itself through natural resources and ultimately threatens continued human survival.
