Population Decline Will Change the Climate for the Better

Stephanie Feldstein, Scientific American - As the human population has doubled over the past 50 years, wildlife populations have plummeted by an average of 69 percent. We’ve already altered at least 70 percent of Earth’s land, with some reports putting that number at 97 percent... For those more worried about economics than life on Earth, the World Bank estimates that ecosystem collapse could cost $2.7 trillion a year by 2030. Deloitte recently estimated climate chaos could cost the United States alone $14.5 trillion by 2070 as we respond to the increasingly frequent and intense damage caused by extreme weather and wildfires, and the threats to communities, farms and businesses from droughts and unpredictable weather. While many assume population decline would inevitably harm the economy, researchers found that lower fertility rates would not only result in lower emissions by 2055, but a per capita income increase of 10 percent.
