Comment Glyphosate over--use (Score 1) 320
However, it's also gone beyond the original intended purpose (killing weeds), and is used as a desiccant. To make wheat easier to harvest, it is soaked in glyphosate to speed the drying process pre-harvest.
That's convenient for the farmers, but there are a lot of studies showing links between celiac'ism etc and glyphosate overuse. Notably, a lot of people with gluten intolerance seem to be able to eat wheat-products in Europe (where the roundup/glyphosate use is often banned), but get sick when eating it in the US.
