Roundup, and its important ingredient glyphosate, act on a biological pathway only found in plants. In the American legal system, science is basically irrelevant in a jury trial, though, so anyone can sue over anything. Only in an appeal will science in science and health lawsuits be important.Yet sometimes the science is so clear no jury outside California is so opposed to evidence that they will find harm. That is why Monsanto has prevailed for a fifth time against claims that a compound that only acts in plants magically caused someone's cancer. And the only financial victory anti-science activists and their predatory lawyers got was gutted on appeal, because judges looked at the science rather than emotion.
