Scientists1 are trying to make the deserts3 into a good land4 again. They want to bring water to the deserts, so people can live and grow plants there. They are learning5 a lot about the deserts. But more and more of the earth6 is becoming deserts all the time. Scientists may not be able7 to change the deserts in time. Why is more and more land becoming deserts? Scientists think that people make deserts. People are doing bad things to the earth. Some places on the earth don't get very much rain. But they still don't let the hot sun make the earth even8 drier. Plants don't let the wind blow the dirt9 away(吹跑). When a little bit10 of rain falls, the plants hold the water. Without plants, the land can become desert2 much more easily11.
