2017] HUNGER AND EQUITY 205
outpaced population growth for quite some time now. We just do not use that food
to feed the people who are food insecure. Instead, an increasing percentage of grains
that would otherwise be available for human consumption has been diverted into
livestock production
and biofuels.
Biofuels currently claim 40% of the U.S. corn
crop, and 23% of the soy crop. Animal feed takes a comparable share. That leaves
only 20% of the corn and 50% of the soy available for human consumption. There
is no reason to think that increased production alone will change this dynamic.
The United States alone raised nearly 90 million cattle for food in 2015,
resulting in production of 23.69 billion pounds of beef.
Across the globe there
were roughly 1.5 billion cattle, 19.6 billion chicken, and 977 million pigs.
It takes
2 and 4 pounds of grain to produce one pound of chicken,
3.5 pounds of grain to
produce one pound of pork,
and 6 pounds of grain to produce one pound of
the highest caloric demands. Estimated Calorie Needs Per Day by Age, Gender, and Physical Activity

SFT4-GK8D] (last visited Feb. 9, 2017). With a global population of roughly 7.3 billion people, that
means current production is 2.117 trillion kcal/day. See Robert Schlesinger, The 2015 U.S. and World
Populations, U.S. NEWS (Dec. 31, 2014, 12:00 P.M.), http://www.usnews.com/opinion/blogs/robert-
schlesinger/2014/12/31/us-population-2015-320-million-and-world-population-72-billion [https://
perma.cc/JC8M-DG5A]. Divide that by 9.6 billion or 10 billion people, and the resulting production is
2205.76 or 2117 kcal/person/day—enough to meet the nutritional needs of a global population that
range from 1000 kcal/person/day per day for young children up to 2800 kcal/person/day for the most
active adult males. See Estimated Calorie Needed Table, supra.

http://www.fao.org/docrep/014/i2373e/i2373e.pdf [https://perma.cc/UDU5-ZYD2]. By 2050,
demand for meat and dairy products is expected to rise by 58% and 63%, respectively. This growth is
driven not only by population increase but also by changing consumption patterns linked to increasing
wealth. See id. at 79 tbl.15.

used to produce ethanol. Id. Another 45% of the corn crop went into animal feed. James Conca, It’s
