Monsanto paid a bunch of scientists to "discover" that Glyphosate, the patented active ingredient in their RoundUp weedkiller is safe for humans, but the article was ghost-written by Monsanto employees without acknowledgement. The article claimed that Glyphosate does not cause cancer, but The World Health Organisation found that it does. Some people have trouble figuring out who is lying between the company making vast profits and the organisation tasked with keeping people healthy across the globe. RoundUp is used a LOT on genetically modified foods made by guess who to be "RoundUp ready" - resistant to RoundUp. These genetically modified foods were also found to be safe initially, but guess who funded that research who are only now, 25 years later, found to be ghost writing the articles instead of letting the scientists do their own work and draw their own conclusions.
