Hey Carol! It is so crazy to think that the scientific technology exists to actually resurrect the woolly mammoth, and to think they could combat climate change too! I sure hope that scientists are successful with this endeavor, especially within our lifetime, so that we could see the results. However, I do agree with many of the ethical concerns that you presented. We have no way of knowing how the reintroduction of this new species could impact the environment. Also, I don’t think this project would be worth the cost and effort if scientists were only able to recreate one hybrid species, and it would live the rest of its life in a zoo. I definitely think it will be interesting to see what happens in the future.
