We clearly agree that there's a problem of implementation... and again - I think most of the problems that GMO is applied to have a lot more to do with exclusivity and monopolistic tendencies than they do with solving agricultural problems. Take your "change in weather tolerances/requirements." part of agriculture is in selecting varietals that adapt better to the particular microclimate of a farmer's plot. Been that way since Babylon. When you take something that wasn't originally there and introduce it, you run the risk of an invasive species. An invasive species that's genetically engineered to defeat the pests that keep the plant from thriving? definitely an invasive species... unless you introduce one of those lovely terminator genes, at which point we're back to square one.

If it takes ten years to breed a crop that can tolerate one zone hotter or colder or five years to genetically engineer a crop that can tolerate three zones hotter or colder, I'd rather go with the 10 year plan. There's a checks'n'balances thing that comes about through breeding that you don't get with GMO.

And that's my whole point, really - GMO has the potential to solve a lot of problems, but the current state of technology, from what I've been able to gather, doesn't have much of a leg up on traditional approaches once you eliminate the nasty Monsantoism of it all.
