> Stopping and even reversing deforestation is the single most efficient form of CO2 reduction/capture we have available. No it isn't. Reforestation might be the most aesthetically and ideologically pleasing option, but it's not the most physically effective one. Trees get you $25-$50/ton-CO2 removal costs; accelerated weathering gets you around $8/ton-CO2 [2]. Iron enrichment of the ocean can get you down to around $1/ton-CO2 removed. Focusing on pretty solutions in harmony with nature will lead us down the wrong path. Every great thing mankind has done has been the result of science, technology, and industry. We don't fly around the world by stupidly copying birds, and we won't get control of the climate by sowing plants.
