It depends on the type on animal

Probably not very long because there are under 2000 left. :'(
we should have a plant because plants give us fresh air so we should not destroy it so have a plant take care of it we need to have an animal because they become extinct so we should have one and take care of it
They'll become extinct, and will never come back! :(
It has to do with the food chain. Say if T-Rex are extinct, the animals it eats over-populate and take all the food or water. Slowly, all the animals start to become extinct. Or, if a certain animal becomes extinct, the things it eats over-populate and the things that eat it normally become extinct.
Yes you can You take an egg or sperm sample and mate it with a similar animal to make it 1/2 of the endangered species then you keep doing this process until you have a creature that is 99.9999999% of the original animal
it erupted because we also not take care
Take away the ice or melt it.
an animal that will soon be extinct, very low in numbers
They aren't extict. Birds are dinosaurs.
