UNITED NATIONS INTERNATIONAL YEAR OF FORESTS 2011

摘要

Forests are biologically diverse systems providing shelter to people and habitats for animals.They are also the basis of more than 5,000 products — from aromatic oils distilled from leaves to medicines, fuel, food, furniture and clothing. Forests also prevent soil erosion, regulate climate and provide clean water. All are vital to the survival and well being of people everywhere — all seven billion of us!
