By Tom Randall – If animals were stocks, the market would be crashing.
To say the index of animals is underperforming humans is an understatement. More than half of the world’s vertebrates have disappeared between 1970 and 2010.
Humans are currently drawing more from natural resources than the Earth is able to provide. It would take about 1.5 planet Earths to meet the present-day demands that humanity currently makes on nature, according to the WWF (pdf).
If all the people of the world had the same lifestyle as the typical American, 3.9 planet Earths would be needed to keep up with demand. more> http://tinyurl.com/mdb9wjg
