what are the Ethical Issues on genetic evolution

I know one, BT Corns. For the ethical issues: a) Human genetic evolution - most people view this negatively because of the idea that a mere human can modify or even create another human using genetic evolution is somewhat equated to "disrespecting God". It's as if saying, "Father, I don't like your creations of the natures in this world. I'll instead create my own." b) BT Corns - it's a 50-50 negative to positive issue. The negative is the "unnaturalness" of the food to be taken by the body. The positive would be the idea of sustaining the supply of food for our future through genetic technology.
