Woolly Mammoths to Return
We could soon see woolly mammoths - or at least animals that are very like them - walking the earth once again. An American company called Colossal plans to use genetic engineering to add woolly mammoth traits to Asian elephants. They claim the resulting hybrid will look and sound like a woolly mammoth. They also say it will be able to live in the same environment under the same conditions that mammoths once did.
Woolly mammoths coexisted with early humans, and they mostly went extinct about 10 000 years ago, with a few lasting until 4000 years ago. They were similar in size to today’s African elephants, although they had very long tusks and a coat of hair.
Colossal claims the de-extinction of the woolly mammoth could help us fight climate change. The intended home for the mammoths is Pleistocene Park in Siberia, Russia. At Pleistocene Park, scientists are trying to repopulate the area with large animals that, through their natural activities, will change the tundra to grassland. If achieved, this will lead to less emission of greenhouse gases.
However, some critics think there are better ways to help the environment. For one thing, it will take a long time to raise enough mammoths to have any significant environmental impact. Others compare the project to Jurassic Park to point out that genetic engineering can have unexpected results.
