Meet John D. Liu, the environmental film maker who says "it is possible to regenerate large-scale damaged ecosystems."
The documentary film looks at restoration projects in China, Africa, South America and the Middle East, who aim to rejuvenate eroded landscapes.
Permaculture teacher Geoff Lawton, who stars in the film states: "The world gets more and more complicated all the time but the solution to fix the major problems of the worlds ecosystems remains reasonably simple. We have to go ahead on a major scale now. Everybody can do their back yard but we have to change the major eroded landscapes into the functional ecosystems they should be."
Spreading the message of change
The key message here is that change is possible. Regenerative efforts that were previously thought impossible have now been proven in many places across the globe, but for these efforts to make a difference, we must implement them before we reach a crisis point where we are no longer able to feed a significant portion of the world's population and are faced with mass-migration.
In the final moments of the film, Lawton says "There's not too many people in the world in my view, it's just that most people don't realise they are acting in a very negative way in relation to the environment. We have to change everything around into a functional relationship."
