De-extinction is a good idea. Using genetic science for reanimation may help adapt existing ecosystems to extreme changes in the environment, like global warming, and potentially reverse them, writes George Church in Scientific American. Bringing back extinct species, like the Woolly Mammoth, may also help preserve animals by restoring lost genetic diversity, adds Church.
De-extinction is a bad idea. The risks of using this scientific technology to revive extinct species like the Woolly Mammoth are too high, writes Jeff Laguerquist of CTV News, as no one knows if they will transmit diseases, put people in danger, or how they will interact with existing biodiversity. Therefore, it's better to answer these questions first before experimenting with reanimation, says Laguerquist.
