The real jurassic park - rebirth of extinct species

Would you like to see mammoths roam the Siberian wilderness again, or risk running into an auroch on your evening stroll?

It is more than twenty years since the movie Jurassic Park first fascinated the whole world, and now scientists are trying to make the fiction reality. Researchers around the world are busy trying to bring back species using advanced genetic technology. The animals range from rhinos and pigeons to dinosaurs, and the reasons for bringing them back range from curiosity to fighting climate change.

We will soon be able to revive lost animals, but is it really a good idea?
