The basic fact, however, is that the big money has gone to making "pesticide" GMs, which are the only ones on the market. Where R&D is at with nitrogen-fixing, I don't know offhand. There is, however, hype in holding out the promise of plants that will need less water, less fertiliser, and will produce double yields of more nourishing food: a hypothetical free lunch.
Eating less meat was not an option P.K. endorsed, though S.S wisely pointed out the health bennies, and how much it would save the NHS.
as for GM food, i suspected that this would be the advocates' technique, to point to some potential future fantasy, while the real agenda is to sell more roundup, and much worse even, force farmers to rebuy seed every season. ~"When an inner situation is not made conscious, it appears outside as fate."
