Lots of great suggestions already. Off the top of my head, one not mentioned so far is Ocean Warriors (2016) about Sea Shepherd chasing an illegal fishing vessel across international waters. It's quite gripping as a documentary, but also does a good job of highlighting the Tragedy of the Commons that is international fishing and the failure of governments to prevent it. https://www.amazon.com/Ocean-Warriors-Season-1/dp/B09238BH7L https://www.amazon.com/Ocean-Warriors-Season-1/dp/B09238BH7L
