Scientists Propose Reintroducing Extinct Species to Slow Climate Change

Of all the varied and incredible possibilities presented by the controversial new gene-editing technique known as CRISPR-Cas9, perhaps the most intriguing are efforts to bring animals back from extinction. Candidates for de-extinction, as the process is known, include species like the passenger pigeon (the last one died in captivity in 1914), the dodo (last seen in 1662) and the sea cow (1768, a mere 27 years after it had been discovered by Europeans.)

These projects are not pipe dreams.

Dr. George Church, a molecular biologist at Harvard University who is working on such projects, estimates that a variation of the first new woolly mammoth (which disappeared some 4,000 years ago) may be born as soon as seven years from now. Like other proponents of de-extinction, he hopes the animals will play a key role in slowing or reversing climate change.
