“Deserts are advancing and water is becoming scarce. It all seems hopeless… But one man has discovered how to make deserts green and our planet healthy again.”
“It is possible to rehabilitate large scale damaged ecosystems… Why don’t we do that?” – John D. Liu
John D. Liu filmed Hope in a Changing Climate, following the Loess-plateau in China where local people redeveloped the land from a terribly damaged area into a functioning ecosystem. This documentary follows Liu explain what he’s learned and what he thinks we should do to revitalize ecosystems.
The process looks something like this:
- Setting aside land for natural vegetation to return
- Exclude grazing in the first 3 years.
- Wait for native plants to return to the land.
- Allow the microbial communities to grow within the habitat.
- Encourage more organic matter, more biomass and more biodiversity.
“We need to redefine and revalue our belief systems. Money is a belief system. There’s nothing wrong with money, as it turns out. The problem is – what is money based on? If money is based on functional ecosystems, then the future will be beautiful. If money continues to be based on the production and consumption of goods and services we’ll turn everything into a desert.”
