One morning a rabbit is hopping on the grass. She meets a zebra.
Rabbit: Good morning Granda Zebra. What are you doing?
Zebra: Good morning little Rabbit. I'm eating grass.
Rabbit: I like eating grass too. But the grass is not good because there are a lot of chemicals on it.
Zebra: Yes you are right. We can't eat it.
Rabbit: We should tell people not to do that. Because animals and people are friends.
