I don't think there have been any long term, in depth studies on whether or not GMO is safe for human consumption.
Let's not forget that the corporations pushing for GMO, like Monsanto are HUGE, mega corporations that have a lot of money and influence at their disposable. Even scientists and studies can be bought off.
If GMO didn't have such potential to contaminate non GMO crops, i would be much more ok with it, "Sure, eat your franken foods as long as i have access to non franken foods.."
However, clearly cross contamination whether accidental or secretly forced is a huge problem. Also, besides that, it seems that the intentions of corporations like Monsanto are pretty sinister in that they seem to have a plan to eventually replace all natural seeds and foods with GMO versions. Why, more profit, a GMO crop or seed, or whatever can be copyrighted and legally controlled.
This is why they have went to lengths to develop "terminator seeds". Seeds that produce plants/crops that do not reproduce viable seeds for the next crop. Why? So the farmer has to keep buying seed from them every year. If this is not akin to pure Evil, i don't know what is. Food and water are our most basic and important necessities and we should not be allowing huge corporations to tamper with these for their own nefarious, greed and profit driven ends. I really feel like yelling right now, but i won't.
Jerry, sometimes i wonder about you. On the surface you seem to be liberal and somewhat progressive, but at other times you just say the darnedest, pro government, pro system and corporations things. Hard to reconcile the two aspects sometimes.
