it's getting dirtier and warmer now. Natural disasters happen more often than before. For example, there was an earthquake in Japan in January. People and animals are in danger. 
       Why does this happen? First, there are more and more people on the Earth. Second, people cut down forests and kill too many animals. Also, more and more smoke and waste cause climate change.
       What can we do then? I think everybody can do something to help save the Earth. For example, we shouldn't eat wild animals. We can also use both sides of paper and plant more trees. 
       I hope our Earth will become more and more beautiful.
