Glyphosate, the main ingredient in RoundUp, is sprayed on millions of acres of non-organic crops around the world. Biologists have concluded that glyphosate has contributed to the 80 percent decline – and possible future extinction – of Monarch butterflies. The World Health Organization in 2015 classified glyphosate as a “probable” human carcinogen, triggering more than 100,000 lawsuits – and so far, three court judgments – against Bayer for allegedly causing their non-Hodgkin’s lymphoma and other cancers.
