Garbage everywhere

When I see some rivers and forests, I see them filled with rubbish. Even they are covered with colorful packages of the garbage which were brought from people. I think that first thing we must do to save Earth is reducing rubbish. If we reduce garbage, there will be less producing of petbottles and papers. Then we are not necessarily consume our resources which will lead to saving Earth. Thinking about petbottles, we use them everyday and change them day by day. Although petbottles are made very tough and strong, we discard them away. We definately have to reconsider about this. Recently petbottles which will melt in water are invented for scientific research. This petbottles will experinment how discarded rubbish stack in rivers. Next year these petbottles will be floated. I hope they will contribute to the research so that humans can be aware about the way we throw away our garbage.
