Forests

The world's forests are the natural habitats for millions of species of plants, insects, birds, reptiles and mammals. They also help produce clean oxygen. Because of illegal logging,forest fires and climate change, the world's forests are disappearing at the rate of 146,000 square kilometers a year.That's about the same size as Nepal. t one time, half the land on the Earth's surface was covered by forest.Today, it is about a quarter.The WWF spends US$40 million a year to protect existing forests and to plant new trees in deforested areas.

Oceans

About two thirds of the Earth's surface is covered by the seas which are home to millions of species of plants and animals.The sea is also an important source of food for all of us.Without the seas, we could not live.But, because of pollution and over-fishing, many marine species are in danger.The WWF has the largest marine conservation programme in the world, and works closely with governments to protect sea life.
