Save our planet, that’s the motto of environmentalists. Well, I think we all should be saving our planet too. Use as less plastic bag as possible because plastic trash is the most un-recicle-able trash. Of course we cannot live without poly bag or plastic bag, but we can make them reusable. I care about increasing pollution in this earth these days, so I want to encourage you to use twist tie to seal poly bags so they can be more reusable.
