Lester R. Brown

Lester R. Brown is one of those few people who understands complex issues before his contemporaries and can then clearly explain his thoughts to enlighten the rest of us. Here is an excerpt from pg. 5-6 in my favorite book, 'Eco-Economy' by Lester R. Brown (2001):

The gap between economists and ecologists in their perception of the world as the new century begins could not be wider. Economists look at the unprecedented growth of the global economy and of international trade and investment and see a promising future with more of the same. They vote with justifiable pride that the global economy has expanded sevenfold since 1950, raising output from $6 trillion of goods and services to $43 trillion in 2000, boosting living standards to levels not dreamed of before. Ecologists look at this same growth and realize that it is the product of burning vast quantities of artificially cheap fossil fuels, a process that is destabilizing the climate. They look ahead and see more intense heat waves, more destructive storms, melting ice caps, and a rising sea level that will shrink the land area even as population continues to grow. While economists see booming economic indicators, ecologists see an economy that is altering the climate with consequences that no one can foresee.

As the new century gets under way, economists look at grain markets and see the lowest grain prices in two decades--a sure sign that production capacity is outrunning effective demand, that supply constraints are not likely to be an issue for the foreseeable future. Ecologists, meanwhile, see water tables falling key food producing countries, and know that 480 million of the world's 6.1 billion people (now 6.5 billion) are being fed with grain produced by over pumping aquifers. They are worried about the effect of eventual aquifers depletion on food production.

Economists rely on the market to guide their decision-making. They respect the market because it can allocate resources with an efficiency that a central planner can never match (as the Soviets learned at great expense). Ecologists view the market with less reverence because they see a market that is not telling the truth. For example, when buying a gallon of gasoline, customers in effect pay to get the oil out of the ground, refine it into gasoline, and deliver it to the local service station. But they do not pay the health care costs of treating respiratory illness from air pollution or the costs of climate disruption.

Ecologists see the record economic growth of recent decades, but they also see an economy that is increasingly in conflict with its support systems, one that is fast depleting the earth's natural capital, moving the global economy onto an environmental path that will inevitably lead to economic decline. They see the need for a wholesale restructuring of the economy so that it meshes with the ecosystem. They know that a stable relationship between the economy and the earth's ecosystem is essential if economic progress is to be sustained.

We have created an economy that cannot sustain economic progress, an economy that cannot take us where we want to go. Just as Copernicus had to formulate a new astronomical worldview after several decades of celestial observations and mathematical calculations, we too must formulate a new economic worldview based on several decades of environmental observations and analyses.

Although the idea that economics must be integrated into ecology may seem radical to many, evidence is mounting that it is the only approach that reflects reality. When observations no longer support theory, it is time to change the theory--what science historian Thomas Kuhn calls a paradigm shift. If the economy is a subset of the earth's ecosystem, as this book contends, the only formulation of economic policy that will succeed is one that respects the principles of ecology.

The good news is that economists are becoming more ecologically aware, recognizing the inherent dependence of the economy on the earth’s ecosystem. For example, some 2,500 economists--including eight Nobel laureates--have endorsed the introduction of a carbon tax to stabilize climate. More and more economists are looking for ways to get the market to tell the ecological truth. This spreading awareness is evident in the rapid growth of the International Society of Ecological Economics, which has 1,200 members and chapters in Australia/New Zealand, Brazil, Canada, India, Russia, China, and throughout Europe. Its goal is to integrate the thinking of ecologists and economists into a transdiscipline aimed at building a sustainable world.
