Sometimes they grow bigger. Sometimes they get smaller. The worlds biggest desert, Sahara, is in Africa. Right now, the Sahara desert is growing fast.Why is the Sahara growing? In some places, people farm too much. In other places, animals eat all the grass, or people cut down the trees. This makes the soil(土壤) weak. Weak soil lets the desert grow.Why is it a problem? People cannot grow food in the desert. People cannot build houses, hospitals, or schools in the desert. So people must leave their homes. They must live somewhere else. What can people do? They can plant trees. They can also farm less. These things make soil stronger. Maybe the Sahara will stop growing. Its a big problem. Many people must work together to solve(解决) it.()1.What is the main idea?A.
