At one point not too long ago the US was producing up to 90% of our own oil supply, is that not the case anymore or am I misremembering that all together? To clarify, I don't recall if that was actually kep in country or the net import/export comparison, we may have been making enough to cover something like 90% but exporting that overseas. Anyway, 100% agree fertilizer has been a problem for a long time. As long as we treat food production as an broken loop where farms are dependant on outside resources rather than building sustainable farming systems we'll always be stuck trying to steal someone else's nutrients in the form of fertilizer.
