Our viewpoint
When we litter one piece of trash, it affects pollution drasticaly.
Usually we would view that world as a beautiful place.
Sun shining everywhere, birds chirping, wind blowing through the trees.
We don't know that our one piece of trash add up to all of this.
The Actual World

Diseases are getting more and more visible.
The diseases thus get carried around spreading to different places.
People are getting to lazy in this world.
We are to lazy to get our trash and put it in the trash can.
