We are losing huge areas of forested land. Logging causes pollution of rivers. Animals, birds and insects are losing their homes. Many industries and businesses need timber. The new logging operations are good for the area because they provide jobs and money. We are very careful when we use fertilizers and chemicals. LANGUAGE FOCUS 03 Cause and effect Melinda says: When we cut down trees from a wide area, rain washes away the topsoil and causes erosion. This leads to pollution of rivers, as the fertilisers are washed away with the soil. When something makes something else happen, we call this cause and effect. In the first sentence, rain is the cause. Erosion is the effect. 76 QUESTLANGUAGE
