Complexity and unsolved problems are at the very heart of the sustainability challenge, and at the very heart of M.S. Swaminathan's thinking and essays. In 1798, Thomas Robert Malthus offered the piercing insight that geometric population growth would inevitably outstrip food production, leaving society destitute and hungry.
