CAMBRIDGE, MASSACHUSETTS — Geneticists led by Harvard Medical School's George Church are seeking to bring the woolly mammoth back to life 4,000 years after its extinction, and have secured $15 million of investment, according to CNN. <br /> <br /> <br />Supporters of the idea believe their return to the Arctic could help recreate a grazing ecosystem, trampling down and compacting snow, which makes it less likely to melt and release methane and carbon dioxide into the atmosphere, according to the BBC. <br /> <br /> <br />Supporters also speculate that because ‘mammoths are like walking bulldozers’ they could be used to level forests and shrublands that have sprung up in the Arctic, which would mean sunlight-reflecting snow remains in those areas longer. <br /> <br />
