In 1620, about half the USA was covered(覆盖) by forests. Today the forests have almost gone. A lot of good land has gone with them, leaving only sand(沙地). China doesn't want to copy(抄) the USA's example. We're planting more and more trees. We've built the " Great Green Wall" of trees across northern(北部的) part of our country.The Great Green Wall is 7,000 kilometres long, and between 400 and 1,700 kilometres wide. It will stop the wind from blowing the earth away. It will stop the sand from moving towards the rich farmland(农田) in the south. More "Great Green Walls" are needed. Trees must be grown all over the world. Great Green Walls will make the world better.
