A wonderful and vitally important film reminding us that throughout and after the current pandemic, the most important crisis of all is still clear and present: humankind's destruction of the natural world. After tracing a trajectory of unremitting unsustainable a) population growth, b) atmospheric CO2 increase, and c) loss of wilderness and biodiversity, Attenborough does manage to leave us with hope and a chance to amend our ingrained bad (disastrous) habits. What a fantastic "witness statement" from a most remarkable lifetime!
