We should use the "R theory," which stands for reduce,reuse,recycle and refuse. First,reduce means having less garbage than usual by eating snacks like bananas and oranges that are not in packets. Second reuse means using plastic bags and bottles again,possibly to keep things in. Third recycle means using old things to make new ones and using certain vegetables to improve the soil in our gardens. Finally, refuse means not using products that are harmful to the environment
