There is nothing new about people cutting down trees. In ancient times, Greece, Italy, and Great Britain were covered with forests. Over the centuries those forests were gradually cut back, until now almost nothing is left. Today, trees are being cut down more rapidly. A major cause of present destruction is the worldwide demand for wood. (67) In industrial countries, people are using more and more wood for paper, furniture and houses.There is not enough wood in these countries, therefore they have begun taking wood from the forest of Asia, Africa and other countries. Wood is also in great demand in developing countries. (68) In many area, people depend on wood to cook their food. As the population grows, the need for wood grows. But when too many treesare cut down, forests are destroyed. In reality, there is usually no chance to grow back. In this way, many millions of acresof forestsare destroyed every year. (69)The destruction of forests affects first the people who usedto live there. It also hasother effects far way. For example, trees help to absorb heavy rains. When the trees are cut down, the rain pours all at onceinto the river. (70)But finally, the loss of forests may have an effect on the climate of our planet. Together with increasing pollution, it could causetemperature to rise, and the climate will change around the world. No one would know exactly what effects the world have on our life. For many people the effects would probably be destructive. 66、 There is nothing new about people cutting down trees. ____________________________________________________ In industrial countries, people are using more and more wood for paper,furniture and houses.
