Environmental Cost of China's Growth

When the Chinese government tried to calculate a national "Green G.D.P.," the formula showed the soaring economy in a more sober light. (Remember G.D.P. stands for Gross National Product, the total amount of goods and services produced by a nation's economy in one year.) This report is about China's attempt to balance economic growth with environmental responsibility.

The video report can be watched here. It is mostly interviews with experts, but very informative.
