We will avoid huge economic costs, if we address climate change, and we will save lots of money in the long run, by moving to renewable energy.
Increasing carbon in the soil - which will remove it from the air - will also have big benefits. Each gram of carbon in the soil can absorb at least 8 grams of water (and as much as 20gm in some soils), and the biology that created the soil increases, with more carbon. And nutrients are held in the carbon, as well.
Carbon bonds with
everything. We can clean up brown fields with carbon, too.
