GL, you would be surprised how successful GM crops can be in harsh environments where traditional agricultural techniques fail miserably. This of course ends in overpopulation and the associated poverty and problems.
IMHO, the biggest danger with GM crops has already been realised, in the form of one to two billion extra humans that would not exist if the technology did not!
I believe most of the soy in the USA, and perhaps even the world, is GM at this point. Nothing like using the world as a petri dish and potentially very useful technology for an egalitarian endgame..
I'd love to debate this further tonight but I need to hit the sack, it's been a loooong day! But one thing before I go, GM crops haven't totally been proven to be harmful (though several adverse things have come to light recently) but they haven't been proven to be 'safe' either. They haven't been around long enough and the jury's still out on that.
There was a report recently of GM crops self destructing lately, in WA I think it was, and there's an investigation into 'why'- but I haven't heard anymore on that yet.
