"up by 40%" only on a study of people living on or near farms where glyphosate is sprayed.
Actual probability you will get NHL from roundup if the figures are accurate (again, limited study results, no causation found), in the worst case, goes from 2% chance to 2.8% chance.
Amazingly, none of this considers the additives to roundup that aren't glyphosate, which everyone agrees are much more likely to hurt you. The case seems to hinge on the least harmful part of Roundup.
This whole case is a great example of a lack of scientific literacy and a whole lot of fear, combined with a dislike for large corporations, resulting in a whole lot of disinformation. Roundup might be bad for you, but we still don't actually know, because we have no causative proof.
