What are some ways to prevent clear cutting?

If we really care about the CO2 in the atmosphere then we need to cut down less trees and re-plant those we have already taken out, then plant another 6 Billion more, yes that is a Billion with a "B". Land Clearing, deforestation and other issues is a huge calamity.

The Rain Forests in Africa, Amazon and other places also at severe risk. Trees take CO2 and turn it to oxygen, and if we plant 6-8 Billion trees we might solve the Climate Change, greenhouse problems. Indeed, we are losing 2-acres a minute as has been noted. Lots of issues out there indeed.

Studying this stuff in the online think tank and all the inter-related issues makes me worry about linear thought guiding our policies, when we need a multiple variable approach and non-linear thinking approach to truly be prudent. In fact we have the technology to use UAVs to fly over and plant more trees.
