I’m only part-way through this but “Buried with Michael Sheen”, which is about toxic waste, is shocking: https://www.bbc.co.uk/iplayer/episodes/m002zkql/buried-with-michael-sheen

Monsanto were producing PCBs which are toxic and carcinogenic and dumping the waste in quarries in South Wales. After they were essentially forced to stop production in America in the early 1970s they increased production in Wales, knowing the risks and dangers.

Corporate greed at the expense of everyone else is not a new phenomenon.
