Fighting growing desert

Why do we have desert today? Deserts are not always being1 here. Most deserts we have today were once green lands full of plant life. One of today's biggest deserts is in north Africa. However, in the first centuny BC2, farms in north Africa grew corn3 and weat, to made bread for the whole city in Broom4. How did this area become desert? Both weather and people can help formed the desert, hot weather or very little rain makes the land sun trike that nothing can grow. If people cut down or burn trees and plants to make a land clear for forming, the wind can blow the soil away. And turn the dry land into sand.

Another big problem is farming5 on land is not very good. this poor land can really quickly turn into desert if you farmed too much. one of the biggest course however is when people take that animal to the same field to feed over and over, and the field finally lose all their new treature. because of these problems,deserts are slowly taking over green land to many parts of the world including China. However we can't fight the growing desert.In some parts of China, people are working proving desert for expending6. In xinjiang for example,some farmers are trying use scientific7 farming methods8. These methods make it possible to use less land for crops9. So farmers then can plant trees on the rest of their land. One xinjiang farmer use only half of field to grow his crops last year
