As the world’s population increases, there is growing pressure placed on its resources. Forests, in particular, are being destroyed at a rate of 11 million hectares a year (Brown, 2001). Land is being taken over by farmers for growing crops, and trees are being cut down for their timber. This destruction is causing many social and ecological problems, in particular famine, threats to native people and endangered species and loss of potential medicines. 2 The main problem caused by the use of forests is famine in various parts of the world. People who have traditionally relied on the forest as a source of food and a habitat for wild game, find that their food source is dying off and animals disappearing. Without a reliable source of food, these unique creatures may die out altogether. Slow-growing trees are not given enough time to regenerate as people move back to previously cultivated land before it ha had time to recover. The best forest cover is being lost, for example in Thailand where 10% of the rain forest is lost each year (Brown, 2001). Thin tropical soils are destroyed causing erosion and flooding. Gradual climate change is experienced in areas where forests have disappeared. 3 Another problem is that many species are now threatened with extinction and the ecological balance is altered. There are increasing problems in China in finding the bamboo that the giant panda eats. Denuded forests no longer support the rich diversity of flora and fauna that they used to. The cutting down of trees has forced people in developing nations to find other sources of fuel. In countries such as Ethiopia cow dung is now used instead of wood. This means that the dung can no longer be used as a fertilizer and as a consequence the soil becomes less fertile and crops become poorer and poorer (The Advertiser, 24 October 2004). 4 As more countries turn from Asia to the
