WWF---Half the world animals have gone

[Catherine]

This is a disturbing report. The WWF study shows that half the animals in the world have disappeared since 1970. It is human activity that has caused this.

So we have changed the world, but not for the better.

If we act now we might bring some species back, but for some it is too late. What a mess we have created.
