I agree that ‘better’ is worth doing and we could wait forever for ‘perfect’ to come along while the world burns. However even doing these things won’t return the biosphere to it’s previous condition, we’ve extracted extreme quantities of energy from underground and dumped them into the atmosphere, and our ‘locked in’ climate change will not decrease with those measures alone. We need to restore balance and I can’t see a way of doing it short of significant carbon sequestration - vastly beyond what can be achieved by reforestation.
