BBC Extinction: The Facts
by David Attenborough
This is a good alternative to Racing Extinction, because it is more recent, shorter, and more timely in that it explores connections between biodiversity loss and the COVID-19 pandemic and other emergent diseases. This documentary pretty evenly discusses all of the human-centered causes of extinction, including habitat loss and destruction, poaching and the animal products trade, pollution, and climate change.
This hasn't been released on DVD yet, but if you have a VPN that you can change to a UK server, you can still access it on BBC's website. Otherwise, you might want to stick with Racing Extinction for the time being.
Essential concepts: Biodiversity, extinction, emergent diseases, habitat loss, fragmentation, poaching, pollution, endocrine disruptors, climate change.
