This is a picture that shows earth in a garbage can, to show that we just keep throwing things away and someday we will throw the entire earth in the garbage. Also, the outer space backround is saying that eventually, we will need a large garbage can to fit the earth and all the trash that we created and the only place it could fit would be in outer space because we will need a lot of room. Also, the green part of earth is representing all the pollution that we have created and it is intoxicating the earth.
