Scientists swore for decades that smoking was safe, until it was proven otherwise.
Scientists swore that thalidomide was safe, until it was proven otherwise.
Scientists swore that fen-phen was safe, until it was proven otherwise.
The list goes on and on. This is just a sample: http://prescriptiondrugs.proco...
So forgive me if I don't trust the "scientists". Do I believe that GMO in inherently bad? Of course not. It's simply a method. It's how that method is used that concerns me. When it's done for profit, then I am highly suspect of its safety. When it's done for strictly humanitarian reasons with no profits involved I'd be much more willing to be open to it.
Our history is rife with companies that would poison their own mothers if they could make a buck from it.
