There have been many reports lately on the very harmful effects of Roundup on human cells. One article is linked here: http://www.environmentalhealthnews.org/ehs/news/roundup-weed-killer-is-toxic-to-human-cells.-study-intensifies-debate-over-inert-ingredients

There are many many more, easily found by Googling the ill effects.
Why is it that when we went last week to purchase weedkiller in leClerc, the only product available was yes -- ROUNDUP! Surely the French Agricultural boffins have the same access to this information as I do?
