I think sharing the world means: We are not the only people around. Humans are not the only things that are breathing. We have animals. From a long time ago, we humans are helped by animals and vice versa. Until now, animals are equals to humans. We sometimes have pets as companions. We give them a home and food and in return they are fun playmates. This is why we need to care for animals. We have to save the earth. Save everybody's home and preserve this world for the following generations.
