Based on your information I can understand your distrust of GMO's and I agree that some GMO's are bad, but what about the GMO's that have done good? For instance, in some of the poorer countries families are unable to get the proper nutrition. Food is expensive and so they primarily eat rice as a means to stave off hunger because it is the cheapest food they can get. However rice has only a few essential vitamins in it, so in essence, they are still starving. Scientist created a GMO rice that is packed with various vitamins in it that is essential to growth and development and so it is allowing those who are eating it to get the essential vitamins for them to live healthier lives, especially the children who desperately need those vitamins for their proper growth. I understand there are bad GMO's out there, but there are good GMO's out there as well. GMO's that are more disease and weather resilient to ensure a viable crop. This enables farmers to grow more food so that the price of food either lowers or maintains its abundance so that families are able to feed their children. When the crops do not produce well then the prices go up disabling families from being able to afford to purchase enough food to last for the month. How do you think they lowered the famine rate around the world? Famine is not extinct but it is a far cry better then it once was because certain types of crops were genetically alter to be drought resistant. The past experimentation of GMO food were failures because of the scientist did not consider the long term effects of their modifications on the human body, but currently there are stricter policies on what can and can't be done in the GMO field and those GMO crops have to go through a much longer and extensive testing before it can be approved by both the FDA and USDA to approve them to hit the market. I am not saying that it is a perfect system.... sometimes things do get through that shouldn't, but it is not as dire as you believe it to be any longer.
As for seeds, Do you know why there are less Heirloom seeds available then they were 50 or 60 years ago? I can't remember exactly when, but governments (especially the US) began seed banks because the seed count on "natural" seeds began to significantly drop. It was getting harder and harder for farmers to afford to purchase seeds for their farms because the abundance lowered causing the prices to get higher. The governments (as well as the people) began to become concerned because at the rate it was going, there would be no food to grow in (I think) approximately 100 to 200 years. So as a result, GMO's were hitting the market harder and "natural" seeds started to fill the seed bank. Through GMO plants they were about to increase the food production and stave off the possibility of food shortage.
In the end, it is all up to the individual to decide whether they believe a GMO is safe to eat and I think that no only should GMO's be clearly labelled but information on what modifications were done to the GMO so that each consumer can make their own educated decisions on it. I don't think that all GMO's are bad or should be written off because they are GMO. Processed foods contain harmful elements in them and yet we all eat them whether we know it or not... how many times a month do each individual hit the local fast food restaurant? or buy a box of mac and cheese?
Thank you for your insight though. Oh and by the way, I know about Humulin. I'm on it. I'm type 1 diabetic.
