Once upon a time there was many different species of animals and each one was unique and they all lived together in harmony.

Many years later, Benjamin wished that the world could still be like that. Him and his friend were the last Tasmanian tigers left.

He lived in a zoo with nothing but hard floor and fences. A wild animal can't live in these conditions, so a few years later he died.

Now all the Tasmanian tigers are gone. They're an extinct species. Benjamin was a good boy so he went to extinct animal heaven.

I see all the other Thylacines and the other extinct animals like the dodo birds, passenger pigeons, great auks, and sea cows.

Let's make the humans think of an invention to stop extinction and keep track of the animal populations.
