Scientists are thinking about bringing different species back to life. I think this is very stupid and irresponsible. I think if some species are extinct, they’re extinct for a reason. Why should we alter the world? This could change the food chain permanently if we bring an animal back that hunts another endangered species. Changing the food chain could destroy ecosystems. Are we ready for that? I think this is just going to create problems for us. We should just leave it alone.
