I voted for several. I think genetic engineering has a lot fo risks, and it has already caused a lot of damage to agriculture. GE foods have caused allergies in people and killed monarch butterflies in teh wild.
Still, I think tehre is a lot of potential good to come from GM. Possible fuels made from GM bacteria digesting waste prdocuts (ethanol from switch grass for example), and of course advances in medidcine are possible as well. It is all a matter of taking great care and responsibilty, and not moving forward for profit at the risk of humanity and nature.
