The trouble is they don't say what the new analysis is & whether they have chosen to look at the experiments that give them the result they want, or whether it is a true Meta-Analysis. If, for example, roundup has no effect, then you still wouldn't expect any experiments on birth defects to show a zero result. Half will show an increase, half will show a decrease and it's easy to pick & choose according to your agenda. I have no doubt at all that Monsanto would try to pick ones that don't show a positive effect, but I also know that a group called "GM Freeze" might have their own agenda too.
Don't get me wrong - I don't trust Monsanto one little bit, but GM has tremendous capacity to feed a huge amount of people and in fact (say, with GM spuds being immune to blight) to reduce the damage to the environment caused by fungicides or other chemicals.
