The chance is that there will be only desert left if we do nothing to stop people deforesting the land .

如果我们不采取措施阻止人们砍伐森林，很可能将来会只剩下沙漠一片。

And brazil has done it without deforesting the amazon ( though that has happened for other reasons ) . The great expansion of farmland has taken place 1000km from the jungle .

巴西的成功并没有对亚马逊造成任何破坏（破坏另有原因），耕地开发在离丛林1000公里远的地方开展。
