I'm not really sure I understand the whole "upset the balance of nature" If the animals are indeed brought back, it's not like we would be re-introducing them to the wild or anything. Anyone can see the nonsense in that. The only reason to bring any of them back would be scientific research. No one is going to try and re-introduce the t-rex to North America again, I mean seriously guys. Think. One argument that does make sense for not bring them back is if they carried a strain of some unknown virus that existed thousands, or millions of years of ago. Imagine, if a disease that existed ages ago, was re-introduced to todays world. We'd have no immunity. It makes for a very nasty situation. That's a pretty tough argument that I can understand, not the argument that "These species went extinct for a reason" Um, not really. A big rock came down and wiped the suckers out. It doesn't really say anything about the superiority, or inferiority of the animal. I mean after all, it was a damn big rock from space, not very many things survived it, not just the dinos. In other words, if we are speaking of dinosaurs in particular, they didn't go extinct because nature selected them to be extinct. They went extinct because they were
shit out of luck.
And yeah, I so want a pet t-rex. I'd name it fefe.
