The popular weedkiller glyphosate, the active ingredient in Monsanto’s Roundup, is on the run.

Congresswoman and Presidential candidate Tulsi Gabbard (D-Hawaii) last week called for a ban.

“We need to ban all products containing glyphosate, including Roundup,” Gabbard tweeted on February 16. “It’s poisoning our people, butterflies and other insects, the land and the water.”

And then again today, Gabbard tweeted: “Monsanto proves they’ll do anything to pad their pockets, including manufacturing ‘scientific studies’ to influence the EPA while destroying small farmers. They unleashed the scourge of Roundup on us and should be held accountable for the consequences.”

Also last week the Guardian reported on a broad new scientific analysis showing that people with high exposures to the popular pesticides have a 41% increased risk of developing a type of cancer called non-Hodgkin lymphoma.”

Last August, a jury in San Francisco awarded $289 million to a former school groundskeeper who said Monsanto’s Roundup left him dying of cancer.

But now comes the American Association for the Advancement of Science (AAAS).
