You must admit though that humans will sometimes do misguided things with good intentions? There are many examples of us thinking that we fully understand a process, when in reality we don't. This can and has led to terrible consequences in the past. One concern I harbor is that perhaps with gene modification we will lose the genetic variability that allows animals to adapt and survive and evolve further. Variability also allows species to survive black swan events.
