As technology expands what is possible in our food system, inefficiencies can arise and make it difficult for policy to change as rapidly as our technology does.
Unclean water, poor sanitation, and lousy hygiene—and resulting diseases—combine with poor nutrition as the leading causes of young child mortality and stunting.

Failure to treat water as a strategic, valuable, and limited resource is a direct threat to the global economy; the health of our planet; and the well-being of both current and future generations of humanity.
About 70 percent of the water humans use globally is consumed by agriculture, and a full third of the greenhouse gas emissions we produce come from food production. 
In the book The Last Hunger Season, the intimate dramas of farmers' lives unfold amidst growing awareness that to feed the world's growing population, food production must double by 2050.
