Did you know that it's almost guaranteed that every single species will eventually die out?

In fact, scientists believe that 99% of all animals that have ever lived are now extinct.

Sad, I know, but maybe extinction isn't as permanent as we thought.

Through advances in biotechnology, there are some animals that are on the cusp of resurrection.

It's time to learn about some unbelievable species that just might make a comeback.

You're listening. You're listening to be amazed.

You know how the ice caps are melting and we're all totally doomed?

Well, there might be an interesting solution to that. Bring back the woolly mammoth. These gigantic creatures could grow up to 12 feet tall and weigh 8 tons. That's the weight of 4.5 cars.

Herds of mammoth were once widespread across the mammoth step,

grasslands that covered Europe, Asia, and North America.

Okay, we all know they're neat.

But how will these Wombo-Wollies fight climate change?

Well, across the Arctic tundra, there's

Permafrost, ground that remains completely frozen for at least two years. But thanks to good

old global warming, Permafrost has begun to thaw. When permafrost melts, it releases

carbon into the atmosphere, further accelerating the effects of climate change that will lead to mass extinction.

Geophysicist Dr. Sergei Zimov theorizes that if the tundra can be turned back to grassland,

like it would have been in the mammoth's time, it could stop the permafrost from melting.

Introducing big grazing herbivores disturbs the ground and allows for deeper freezing of

permafrost during the winter.

When summer rolls around, the layer of grass insulates the permafrost keeping it from melting.

I guess we just need to find some mammoths. It can't be that hard.
