Bringing forest back to Earth -The Southern Lights project

»The older the tree gets, the harder you can manage. If you have an avocado tree, which is like 5 m tall and you still pick avocados it is not the same thing as if it's 25 m high and you can not pick them anymore … So you just leave this avocado tree. It will still producing, but you will not be able to manage it. So you just go to the new land. It depends where you are on the earth. In the Amazon it will goes faster as you are in the Alps. It's gona take way more time to go into a primary forest. That's the idea to take the evolution of agroculture to the primary forest, which is defined by the death. Natural death of adult trees.«
