Last time roundup came up here I made the claim that it killed my dad (healthy guy, came from a healthy long lived family, he died about 15-20 years sooner than his relatives from the cancer that is associated with roundup, you can google "non-hodgkin's lymphoma roundup" and you'll see a zillion lawyers wanting to talk to you about it). Yet hackernews people shouted me down saying that it wasn't possible. I'm not an…
There's very little epidemiological evidence to suggest glyphosate is a human carcinogen. Millions of people are exposed to it, some in significant amounts on work sites. If there's any correlation between heavy occupational exposure to glyphosate and human cancer, it's very weak. Similarly: there's not a lot of first-principles logic to carcinogenicity of glyphosate. It's active in a metabolic pathway that animals d…
Glyphosate is hugely responsible for the conversion of massive amounts of land into corn and soy cropland, where reduced pollinator habitat actually reduces crop yields (or requires more agricultural abuses like migratory honeybees).
To say this is a useful chemical is misleading. It's designed to kill things and like all such chemicals, there are significant tradeoffs, regardless of whether it is directly carcinogenic to humans.
