i think the earth is in worse shape because people pollute. another reason i think the world is in worse shape is because people cut down more trees then what they need to do because they think they need infinite paper and fire wood. i think the world was better 50 years ago because there were more trees. another reason is because there was less pollution. finally my last reason is cars weren't as advanced to create smoke
