Some species like dinosaurs we should not bring back!!!!!!!!!! But others like harmless animals and birds, we should. If we brought these back, then life would be so amazing!!! and some species were accidently wiped off the earth, so I think that it would do us all some good to bring those guys back.
I am thinking of humans. I never said that we have to feed the extinct animals, or have them as pets. They would just run wild like everything else. Do lions and fish eat up our food? Do we suffer because of their existence? No and No.
True, although I believe that bringing back extinct animals is a waste of money, time and effort because they died out because they didnt have the traits neccessary to live. So why should we bring them back just to watch them die again?
When you say "fresh start" you must be forgetting what you said last round when you told me that they could just "Run wild" Also, think about what it would be like with a bunch of animals we barely know anything about running wild. That would be too chaotic.
