There're different kinds of animals in the zoo. We see the zoo keepers give them        to eat. They don't have to       food by themselves. They just eat, walk and       all day. So many of       may think that the animals there       happy and lucky. But most       them are sad. Why? They're       free.
Animals like elephants, monkeys and tigers       live freely and happily in       or mountains. Tigers,        example, run, jump, play with their children       catch small animals for food. But now they have to stay in       rooms in the zoo. Their life in the zoo is      different from their life in the forests.
Now many of us think       animals should go back to forests and mountains so that       earth will become better.
