There are many kinds of animals in the world, but not only the humans. We live in the same world, and we should be friends. As everybody knows, the humans are the rulers of the world today, so we should protect our friends--the animals!

    But how can we protect them? First, I think we must stop killing birds and other animals, especially the young ones. Second, we have to protect the environment, to make the sky blue, to make the grass green, to give the animals a comfortable place to live. It's not only for the animals but also for ourselves. At last, we should tell more and more people why we should protect the animals and how to protect them, so that we can make everyone do this.
