The Department of Economic and Social Affairs at the United Nations projects that 9.7 billion people will inhabit the Earth come 2050. With one in eight people today not getting enough food, farmers will have to become more prolific in order to serve these additional billions. As nearly half of the planet's 10 global hectares of potentially productive land is already devoted to agriculture, any expansion will increasingly impact delicate ecosystems that are already declining. What's worse is the World Bank estimates that climate change could cut crop yields by more than 25 percent as the population continues to grow. Feeding this amount of people will require finding new ways of becoming even more efficient at producing food.
