Climate change. Finite fossil fuels. Fresh water depletion. Rising commodity prices. Ocean acidification. Overpopulation. Deforestation. Feeding the world’s billions. We’re beset by an array of natural resource and environmental challenges. They pose a tremendous risk to human prosperity, to world peace, and to the planet itself. Yet, if we act, these problems are addressable. Throughout history we’ve overcome similar problems, but only when we’ve focused our energies on innovation. For the most valuable resource we have isn’t oil, water, gold, or land – it’s our stockpile of useful ideas, and our continually growing capacity to expand them.
