Slash and burn is not necessarily destructive. It has been
sustainable in the past when population density was lower and the
resting time between burns in any given place was long.
at least more of what is chopped down is kept when
using biochar and has a chance of improving the soil.
with slash and burn nutrients run off the top and then
whatever slight improvement is there is gone within a
few seasons.
