I have seen a lot of You Tube videos promoting bio char. I have heard how great it is supposed to be. But I can't help but wonder how it can be good to burn all the materials and create tons of pollution in the air to make it? Can bio char offset the bad with the good.
This is the first article I have actually read that tends to make me think maybe bio char might not be so great, but maybe just another scientific fad.
