Some places on the earth don’t get very much rain.But they still don’t become deserts.This is because some green plants are growing there.Small green plants and grass are very helpful to dry places.Plants don’t let the hot sun make the earth even drier.Plants don’t let the wind blow the earth away.When a little bit of rain falls ,the plants hold the water.Without plants,the land can become a desert much more easily.
