Funny thing about the Monsanto cancer case is that they know that the problem is in the Roundup formulation (including surfactants that are required to get the glyphosate across the waxy plant cell wall barrier) yet Monsanto financed studies on purified isolated glyphosate to demonstrate it didn't cause cancer. Sneaky and dishonest, isn't that? Why not just do the study with the Roundup formulation?
> Mike DeVito, acting chief of the National Toxicology Program Laboratory: “We see the formulations are much more toxic. The formulations were killing the cells. The glyphosate really didn’t do it".

As far as Monsanto and GMO, modifying certain crops to make them resistant to weedkiller just so you can dump more weedkiller on the field... might be good for weedkiller sales, but I don't think 'feeding the world' is the goal here, more like 'maximizing product sales'. Dumping all that weedkiller into lakes and rivers also destroys the base of ecosystems, which is unwise.
