There's like a stag that walks around, that jump, that eats, he looks happy however a leopard comes from nowhere and watch the stag he is hiding when the stag looks in his way, then the stag who is eating hears a sound that makes him run away. The leopard goes out of his hiding place and sees that he just walked on a plastic cup, wich makes him unhappy, at the end a truck with passengers passes and throw a lot of rubbish, wich makes the leopard unhappy.

They shouldn't pollute the earth
They shouldn't throw rubbish
