Absolutely incredible film. Attenborough has led quite a life but he has also witnessed such terrible decline in the health of our planet. As someone raised to believe that God created earth for humans, I had to unlearn so much to realize the reality that humans are not the center of the world but rather the most powerful of all species, and I felt the weight of our exploitation, selfishness, and lack of responsibility. We truly are only one part of the world and I would say not the most important part, though we sure like to live like it. Let this film be a call to action so that generations to come won't be born into a more rapidly dying world.
