Many people litter in many place. What we must do to stop that ?...Let me give my opinion. I think we must turn our trash become something handicraft. Thats will make our earth more clean plus we can earn money from that. But i think not all people can do that so i think we can build a place used for litter. That place must be clean and in that place has cleaning machine for wash the trash. People who can make handicraft from trash can get free the clean junk from that. So our earth not dirty again.
