Despite great advances in understanding of photosynthesis in crops, photosynthesis research has contributed little to improvement of crop production in the past. Does it have a future role in the task of feeding a world of 8 billion? In this chapter I argue that modification of the primary carboxylase of photosynthesis (Rubisco) promises very significant increases in potential crop yields. Plant breeding over the past three decades has produced remarkable worldwide increases in the potential yields of many crops, most notably improvements in the small grain cereals of the “green revolutio…

Since the 2010s, the fertility rate of the United States has declined below replacement level, prompting projections of an aging population and workforce, as is already happening elsewhere in the developed world and some developing countries.
