Answer:
No.
Explanation:
Because we've already messed up nature enough. We were totally fine before we learned about it. Humans aren't extinct. Yet. But, genetically modifying other organisms (including ourselves) I think, is wrong. God or nature (whomever, it doesn't matter) didn't create these creatures for us to experiment on. We were supposed to live in harmony with these animals. So, messing everything up doesn't exactly help.
Have a great day!
