After glyphosate was classified as “probably carcinogenic,” internal Monsanto emails revealed that millions of dollars were spent on ghostwritten papers and PR campaigns to discredit critics. What does the glyphosate controversy show us about conflicts of interest in science?
This is the first video in a four-part series. Stay tuned for:
• What Explains the Different Glyphosate Safety Conclusions? (nutritionfacts.org/video/what-explains-the-different-glyphosate-safety-conclusions)
• Are Consumers of GMO Crops Exposed to Enough Glyphosate to Increase Cancer Risk? (nutritionfacts.org/video/are-consumers-of-gmo-crops-exposed-to-enough-glyphosate-to-increase-cancer-risk)
• The Effects of Glyphosate on Children and How to Reduce Exposure (nutritionfacts.org/video/the-effects-of-glyphosate-on-children-and-how-to-reduce-exposure)
This is the video from 2014 that I mentioned: Are GMOs Safe? The Case of Roundup Ready Soy (nutritionfacts.org/video/are-gmos-safe-the-case-of-roundup-ready-soy/).
