> engineer. nature can plant trees instead. Trees, if left alone for a couple of years will naturally reproduce and plant themselves. The key bit is leaving the space alone. It is not something that really needs engineering on the whole. There is a small amount of places where trees would not be able to colonise if left alone - and we need to use the science of Ecology to examine why. it's here where geotechnology can come into play, but for the vast vast majority of the billions needed, we just need to leave alone . Now, saying that, there is a great benefit in getting children interested in nature and planting trees and so we shouldn't stop planting efforts for that sake. But there is a deeply troubling idea that we can engineer nature to save nature when it's nature that can save itself and us.
