Oh well, its just a different vision, so that can't really be argued.
bob: The logical question then would be, to what ends? Why is Green Peace playing politics, and what does it hope to accomplish. Who will profit from their influence? Again, they must have a concrete agenda which they consider worthy of pursuing, so that would be the first step in understanding them.
also, heavily tested by whom? The biotech companies themselves? The FDA (or similar agency), and if so are they under any sort of pressure to produce favourable results. Does it do its own research, or rely on the observations given to them by the biotech corps? I think the BST milk additive is a pretty good example of what happens when you have a huge apparatus in place, put their by a biotech firm (Monsanto in this case), in order to accomplish a specific goal and science be damned. The fact that the Canadian and British governments (I don't know about other nations, but I would assume they gave a similar verdict), have banned it, while the American government didn't is a testament to the power of the almight lobby group.
