I would love to see an archeological dig in the terra preta soils - TopicsExpress



          

I would love to see an archeological dig in the terra preta soils in Brazil to reconstruct the pottery shards to determine what the charcoal retorts looked like that the ancient Amazonians used to create the rich soils that still exist today. Knowing how the Amazonians made their gasifiers out of pottery would provide the world with a low cost way to restore our soils, reduce poverty in developing countries, while simultaneously remove carbon from our atmosphere.
