Permaculture: Green Gold
John D Liu tells how “it’s possible to rehabilitate large-scale ecosystems”. In 1995 he filmed the Loess Plateau in China where “local people transformed an area almost the size of The Netherlands from a …desert into a large green oasis” and since then has been involved in “greening deserts” around the world. The film begins with world problems but if you get past this the solutions are imaginative and inspirational: from re-introducing “thought to be extinct” species in Jordan to reforestation and rehydration in Ethiopia.
