Three excellent investigative series; the subjects aren't linked, but they're all long-form dives into three tricky subjects; cyberstalking, artificial intelligence, and environmental damage in the Amazon rainforest. Not an easy listen given the subject matter, but very necessary. All good quality, but 'Missing in the Amazon' is perhaps the most urgent; few podcasts I've listened to have quite the emotional punch of some of the scenes in episode 5. I'd rather not spoil, so go and listen.
