The problems with the environment are becoming more and more serious．You may think it is the government's job to take action and it is difficult for the individual（个人）to protect the environment．In fact， there are several easy things that can be done to make a difference．

You can start your cation by learning to recycle． Although this appears really simple，there are many people who still throw glass bottles and metal cans（金属罐）into their common rubbish bins．Do you notice that our government has put many special rubbish bins in public places？They all have glass and metal recycling signs．If you spend a few seconds washing the cans and bottles and put them into the rubbish bin， you will be on the path to protect the environment．

One more big waste product is newspaper． Most people will take their newspapers and throw them into rubbish bins when they finish reading them．In fact，there are many other things you can do with an old newspaper． For example，newspapers are something useful for a perfect shine．

What else you can do is walking a bit more． Many people usually get into their cars and drive one block to get cola at the local shop．If you walk to the shop，you can not only spend less time，because you needn't try to find a parking place，but you will save money on oil． If you wish to save even more on oil，take the chance to share the same car with others．
