Who says U.S. farmers aren't feeding the world?

There have been some to push back regarding the notion that U.S. farmers 'feed the world.'  However, this adds some perspective for consideration:

“Syngenta (2014) reported that the demand for grain has increased almost 90% since 1980 and that each year 2.4 billion tons of grain is consumed annually through food, fuel and feed. The four main contributing crops include soybean and maize (feed), and rice and wheat (food). In South Africa, half of the maize produced is used for animal feed, of which 70% is for poultry (Goldblatt, 2012). Furthermore, any significant rise in the demand for meat results in a similar rise in the demand for grain because one kilogram beef requires seven kilograms grain to produce, one kilogram pork requires four kilograms of grain and a kilogram of poultry requires two kilograms of grain (Syngenta, 2014). It is thus evident that agriculture is mainly demand driven and the grain industry specifically will continue to play a vital role in the global economy. The challenge will be to meet the growing demand by means of increased production.”
