Years ago,many zoos kept all kinds of animals in small cages.
Small cages made it easy for people to see the animals,
but a small cage is not a good place for an animal to live.
Today zoos keep animals in different kinds of cages.
The cages are very big and open.
They usually have plants and a little lake.
The cages look like the animals'habitats.
Zoos help to protect all kinds of animals.
They protect animals in the zoo and they protect animals in the

wild.
How do they do thisZoos teach people how animals live in the

wild.
Zoos want people to help protect the animals' wild habitats.
Why should we protect animals'wild habitats?
Many plants and animals are going extinct.
Extinctmeans that every one of a kind of plant or animal has

died.
The dodo is an extinct bird.
There are no dodos anymore in the world.
Scientists saythat seventy-four different kinds of living

things
go extinct every day!
Zoos are working together to stop animals from going extinct.
