Earth Day

From the ever optimistic economist Mark J. Perry:




Data Source for graphs: EPA

MP: Consider that since the first Earth Day in 1970, U.S. population has increased by 50.25%, miles driven has increased by 159% and real GDP has increased 203%; and yet air quality is better than ever.
In another post, Mark links to Use Energy, Get Rich, and Save the Planet, an editorial by the lonely libertarian on the New York Time's staff entitled :

As their wealth grows, people consume more energy, but they move to more efficient and cleaner sources — from wood to coal and oil, and then to natural gas and nuclear power, progressively emitting less carbon per unit of energy. This global decarbonization trend has been proceeding at a remarkably steady rate since 1850, according to Jesse Ausubel of Rockefeller University and Paul Waggoner of the Connecticut Agricultural Experiment Station.

...

Of course, even if rich countries’ greenhouse impact declines, there will still be an increase in carbon emissions from China, India and other countries ascending the Kuznets curve. While that prospect has environmentalists lobbying for global restrictions on greenhouse gases, some economists fear that a global treaty could ultimately hurt the atmosphere by slowing economic growth, thereby lengthening the time it takes for poor countries to reach the turning point on the curve.
