Big Smile, No Teeth: We're running pell-mell towards a cliff-edge

Screen capture from the 'Our Planet' David Attenborough documentary on Netflix showing the moment one walrus falls off a cliff due to overcrowding caused by the lack of sea ice for them to rest on.

There are few things sadder than watching walruses walk themselves off cliffs to their certain deaths.

If you think this image is some kind of sick joke then you haven’t checked out Our Planet on Netflix, the new David Attenborough documentary series that boasts beautiful wildlife shots and the overall message that humans are leading the world to another period of mass extinction.
