Afforestation is part of the solution but even if we would plant a lot of trees and not use them, this solution does not scale. Current most optimistic estimates think trees can sequester 600 GtCO2 by 2050 max while most estimated think this is around 100 GtCO2 or less. We'll probably need around 1000-1500 GtCO2 of negative emissions.

So yes we need to plant more trees, but we also need to pursue other negative emission technologies such as ocean fertilization/ocean liming, soil carbon sequestration, direct air capture and enhanced weathering.
