The world is going to need better care. We continuously throw away trash that can always be reused. The ocean already has a bunch of junk and trash. It is not good for underwater creatures. These creatures get caught in plastic and sometimes can't get out. The air is polluted way too much. It is not good for the environment. Someways to clean the Earth is to reuse plastic or other trash. This causes less trash to be created. Another way is to pick up trash you see outside, so it won't make its way to the ocean. If you don't want to those things, you can always just sort your trash correctly.  There are other ways to help out the Earth, like going to the beach and collecting the trash you see there. It is a friendly deed you can do to the Earth.
