Dr. Greger does it again. I searched the site for environment to see if I could find some peer reviewed articles, and blam here it is:
This is why its not cool when your neighbors order chicken. Chickens are given arsenic drugs which then is transferred into the environment. Including vegan foods like rice. What goes around comes around. Whether you like or not your communities decisions impact your life and visa versa.
Brief summary: Arsenic drug -> chickens -> soil + water - > vegan foods like rice -> cancer.
Arsenic drugs are fed to chickens, which in turn the arsenic ends up in soil and water, which then makes it to the rice fields, next the rice plant absorbs the arsenic and vegans end up with arsenic in their rice, finally the arsenic leads to cancer.
Here's one of Greger's sources:
