And people often produce harmful gases. It is destroying our Earth.

Trees are our friends. They can take away dust and change carbon dioxide into oxygen for us to breathe. But now, lots of trees are cut by people. There are less and less trees on Earth. 树木是我们的朋友。他们能带走粉尘和二氧化碳转化成氧气。但是因为人的砍伐，地球上树越来越少。Without trees, soil would be washed away. 没有树木，土壤就会被冲走了。When we are destroying our environment, at the same time, it is also bad for our bodies. 当我们正在破坏环境时，我们的身体也不再健康。Don’t throw any rubbish onto the ground. Don’t waste water. Stop using plastic bags for shopping. 不要把任何垃圾扔在地上。不要浪费水。停止使用塑料袋购物。 保护环境就是保护我们自己。Protect environment is
