Although our environment is good now, but there are still many problems that need to resolve. Everyday throughout the world, millions of newspaper and paper bags are screwed and thrown away. All of you will surprise to hear this but this is the true. I think we should recycle more rubbish to reuse it again. Like using its to make toys or manything else. We can use old car tires to make shoes and sandals too. We can do things the same as these things instead of throwing rubbish into the rivers, lakes and seas, making the water unclean, throw out of the streets and public places like park, movie theater and many other places. If there are old clothes in your house, what will you do with them ? Throwing them away? There are many people in the world don't have clothes to wear, so pleased don't throw it away ! Give it to charities. I hope you will do some of my ideas to safe our environment. Our Earth will be more and more cleaner.
