This documentary invites viewers to follow environmentalist Mikael Rioux as he meets exceptional men and women behind innovative projects for the future of society. Earth Keepers profiles India’s Ashok Khosla, head of Development Alternatives, which is putting development back in the hands of local populations ; Canadian John Todd and his “living machines,” which mimic nature for waste water reclamation ; Sweden’s Karl-Henrich Robèrt, developer of the Natural Step method for managing municipalities and large corporations, based on a vision of the future ; and Kenya’s Wangari Maathai, whose Green Belt Movement has seen millions of trees planted by women who are taking the future of their country into their own hands. Earth Keepers is a quest to find concrete solutions to the problems facing our planet. Part survival guide, part hopeful vision, this positive, inspiring documentary is for all those who refuse to give up, despite the enormity of our challenges.
