Im not suggesting it needs to changed, just that much of it is not based upon science, that is my main gripe. Anyone can infuse arcane methods with anything, I still want science.
there are far too many things nature and people of the old days do that cant be explained by science. that doesnt mean its BS. science isnt the end all.
as far as i know science has yet to figure out why terra preta is so fertile after so long, and why it "grows". that doesnt mean its BS.
dont be afraid to think outside the science box. theres a whole world out there to learn from.
