Weedkiller manufacturer ordered to pay dying man £226m over claims it gave him cancer. Did it? And does this case prove anything?

What Monsanto was blamed for
The active ingredient in Roundup is glyphosate. In 2015, the year after Johnson’s diagnosis, the World Health Organization’s International Agency for Research on Cancer classified glyphosate as a Group 2A substance, meaning it is probably carcinogenic to humans. The category includes dozens of other industrial chemicals, as well as the emissions from high-temperature frying, the chemical exposure incurred in work as a hairdresser, and consumption of red meat.
