Sir: Alice Q Swanson (letter, 31 July) informs us that "millions of acres" of GM crops are growing across the US and that to reach such an acreage took some four to five years. Interesting then that I have not noticed headlines about carnivorous two-headed butterflies or crops of giant nettles marching Triffid-like through New York.
Opponents of GM crops would no doubt claim that there has not been enough time to see the real and devastating effects. It is also equally valid, in the absence of proof either way, to examine the issue thoroughly before reaching conclusions which could have far-reaching effects for economies less endowed with the luxury of paranoid speculation on environmental matters.
