PCBs were eventually banned by the U.S.
government, and that meant Monsanto had to figure out what came next.
The company pivoted, in a big way, to agriculture.
One of its chemists developed a new chemical, glyphosate.
It was extremely effective at killing weeds.
And in the 1970s, Monsanto began selling it under the brand name Roundup.
Sales of Roundup were strong, but like other herbicides on the market, it had a limitation.
Once crops sprouted, Roundup didn't just kill the weeds, it killed the crops too.
So farmers could only spray it at certain times of the year, until Monsanto changed the equation.
In the early 1980s, company scientists genetically modified seeds to tolerate glyphosate, the active ingredient in Roundup.
And by 1996, Roundup Ready seeds were on the market.
Now, farmers could spray their seeds whenever they needed to.
The chemical would kill the weeds, but not the crops.
It was a game changer.
There was just one problem, a big one.
Almost immediately, there were safety concerns.
Animals exposed to glyphosate were developing tumors, and studies in the Midwest pointed to higher cancer rates among farmers who used Roundup heavily.
This was the last thing Monsanto needed.
That wasn't going to be easy.
If Monsanto said the product was safe, people weren't just gonna take their word for it.
