Poisonous chemicals and pollutants from various factories enter into the soil, thus causing soil pollution. 【2】 Soil erosion is a serious problem that causes degradation (退化) of soil and leads to floods. Trees and plant roots bind the soil and thus reduce soil erosion. Also they conserve rainwater and reduce sediment(沉积) deposits.

Trees produce oxygen. Trees play an important role in reducing the greenhouse gases. They consume carbon dioxide and produce oxygen. 【3】 A fully grown tree produces oxygen which is sufficient for 10 people for a complete year. Also, they act as filters of the air that we breathe.

Trees are of commercial importance. Trees fulfill the need of fuel for cooking in many areas around the world. Trees also provide timber for furniture and hundreds of household items. Wood pulp is used for making paper in industries. 【4】 Some trees are even used to make medicines.
