中国式话
Look at this blue planet. This is our home. There are plains, mountains, rivers, lakes and oceans on our planet. There are all kinds of trees, flowers and grass on our planet. There are all kinds of wild animals living together with us. Don't you want to keep our planet beautiful? But sometimes we do bad things to it. We waste too much water. We cut down too many trees. We hunt too many wild animals for our food or clothes... We shouldn't do these things. We should save our planet, because we have only one planet.
