I'm pro GMO. I believe humanities next great leap is genetic engineering. Let me explain, when we invented fire, we learned to change matter at a molecular level, harvesting the ability to create and destroy chemical bonds, most of everything today that we have in modern society is directly attributed to fire. Cooked food, fire. Metal smelting, fire. Chemistry, fire. Plastics, fire. Aviation, fire. Gunpowder fire. Maybe you can start to see where I'm going with this, most of everything in your home can not exist without some form of manipulation with fire. We are a society driven by fire. Fire also has caused millions, if not billions of deaths. Without fire, we wouldn't have modern wars, intoxicated drivers, etc. Fire has caused almost as much damage as it has caused benefits...granted, this is arguable, but what's not arguable is that fire is ridiculously dangerous. And nobody from the early days of fire manipulation could have possibly predicted what it would eventually lead to. Space travel, for example.
With GMO's we have entered an absolutely new era, instead of manipulating matter at a molecular level, we have learned to manipulate life at a genetic level. In the same way that early Homo sapiens could not have predicted what benefit or harm fire could have brought, we are also practically clueless as to what genetic engineering will eventually bring about given enough time and curiosity. Will it be dangerous, absolutely. Will it be beneficial, absolutely.
Is, however, there any reason to hamper the ability to move forward into an age of science so great and vast that it's last legitimate rival was fire?
I put effort into trying to be thoughtful and respectful, and I have no qualms with people who don't think the way I do I believe opposing opinions are healthy. I would ask to be extended the same courtesy.
