Even though trying to keep the Earth clean might not seem important, it is almost the most important thing.  First, people should recycle.  They can recycle anything from paper to cans.  The cans and paper can then be used to make something else.  So resources can be saved. 

Another thing people can do is to carpool.  Carpooling saves money and gas.  Gas is also a resource that should be saved because we might run out.  In conclusion, resources need to be saved by reusing and reusing.
