Food For Billions Of New Mouths

It requires the hubris of a TV faith healer to imagine there must be a way to double and redouble the productivity of an acre of soil endlessly as the population grows. The amount of energy from the sun is the same. The chemistry of chlorophyll is the same. How can we ignore the soils are getting worse each year from erosion and salinisation? How can we ignore that massive amounts of arable land are removed from production to serve other purposes? Surely we know much of the advances of the green revolution will reverse as oil runs out. If human ingenuity can solve any problem, why are we not seeing continuous improvement?
