New York Times: Over the last 8000 years, forest cover on the planet has shrunk from about 24 000 square miles to around 13 000 square miles, the advocacy group Global Forest Watch estimates. To call attention to the problem, the United Nations has declared 2011 the International Year of Forests. Various activities are planned to educate the public about the consequences of destroying the planet’s forest cover, including a film series, a commemorative stamp, and an interactive website.
