This week I watched David Attenborough's excellent documentary film A Life On Our Planet on Netflix. David himself describes the film as his witness statement of the destruction of the bio-sphere that he has witnessed in his lifetime. It is harrowing viewing but ends in an optimistic call to action about what needs to be done to stop ourselves from destroying the planet. It is mandatory viewing for everyone, especially for those with children or in positions of power or influence. It can't be said any clearer, either we change or we burn.
