As for that Plos One study, take a look at who the authors are and where they work. They're all members of the pesticides action network and the last author on the paper is also a staff scientist for Friends of the Earth, another environmental NGO. Unsurprisingly, she had an article all lined up with The Guardian on the day the paper was released. The paper itself is nothing but a cludge of unrealistic assumptions and bad math.
