This entire talk covers the process of cloning and resurrecting extinct species. Some of these species cloned are domestic animals, but other species were ones that recently died off thanks to us humans. The speaker then talks about resurrecting long extinct species. You'll notice at the end of the talk that there are some people in the audience who stand, and others who sit. My question is, where do you stand on this topic? Do you think it should be pursued? Do you think we can resurrect creatures such as the saber tooth tiger and the woolly mammoth? Personally I care more about the animals that are here now, the ones that are still endangered and probably will die if humans don't do something. I honestly think the funds would be better off towards conservation than pursuing something as expensive as de-extinction. If the scientists intend to return these species to the wild, they would have to change the present environment - possible endangering species that already live there - and ensure that they have a stable food supply. But the worst thing I can see happening are these animals becoming a curiosity or a billionaire's pet. But again these are my opinions and I'm curious to see what everyone else thinks on this topic.
