Lester R. BrownWorld on the Edge--How to Prevent Environmental and Economic Collapse by Lester R. Brown, WW Norton and Co. N.Y. 2011.

Early studies have concluded that human demands on Earth’s resources exceeded its natural systems in 1980 and in 2007 exceeded Earth’s “sustainable yields by 20 percent.” In contrast, economic date of about 2010 showed a “10-fold growth in world economy since 1950. The fourfold increase in world income was celebrated.

That is good news, Lester Brown tells us in 2011, until we realized that Earth’s recent environmental declines suggest inevitable economic and social collapse following the shrinking of Earth’s forests, soils, aquifers, fisheries and high temperatures

Brown’s Plan B focused on cutting global carbon emissions, stabilizing the human population at 8 billion by 2040, eradicating poverty, and restoring forests, soil, aquifers, and fisheries. Costs, he said, were 1/8 of the 2011 world military spending.

What were we thinking? He also predicted that by 2020 up to 60 million people would migrate from Sub-Saharan Africa to North Africa and Europe. CO2 emissions should be cut to 400 ppm by 2020 so we can reduce it to the 350 ppm recommended. In 2020 a worldwide carbon tax of $200 per ton could be offset by reduction in income taxes. An additional $200 billion could restore Earth’s national systems, by 2020 we should stabilize population and eradicate poverty--paid for by “updating the concept of national security. How different are questions for the world now? It’s already 2020.

Brown’s ideas could still help, if we could change our individual focus. CO2 emissions per passenger mile on high speed trains are about 1/3 those of cars and 1/4 of planes. Do we have to be slaves to saving time? We have been using more solar and building more efficient buildings, but we need to do more. The oceans are filling with plastic, People are desperate for food and safety on too many places for too many wrong reasons. In 2011 government were spending $500 billion per years to subsidize the use of fossil fuels. Simple requirements like rooftop solar, water heaters and energy efficient building.

Brown’s ideas are simple once fully realized. They could reverse the downward trend we have taken since 2011. Think wind, solar and geothermal, a tax on carbon. Raise gasoline taxes and cut income taxes. We could still do it--build a new economy--carbon free. Oystein Bahle of Exxon Norway noted that “Capitalism may collapse because it does not allow the market to tell the economical truth.
