So how can China produce enough safe food for its growing population if they all start eating like Americans? The simple answer is it can't. It takes about 1 acre (half a hectare) to feed the average U.S. consumer. China only has about 0.2 acres of arable land per citizen, including fields degraded by pollution.
Significant agricultural investment has made it possible for Chinese farmers to produce high volumes of staple crops, enabling the country to achieve a roughly one-to-one ratio of grain production and consumption.
