If everybody in the world adopted the North American diet, there would be a shortage of land …. a new study has found. The researchers, from the University of Guelph in Canada, wrote about their study in the journal PLOS ONE.
Adherence to USDA guidelines would require one giga-hectare of extra land under current farming practices, the researchers concluded. One giga-hectare is approximately the size of Canada ….
Therefore, if everybody worldwide adopted the North American diet, we would need an additional farm the size of Canada. Otherwise, we would not have enough land for our dietary requirements.

Global lands are a limited resource. Therefore, there should be international coordination of dietary guidelines, the authors suggested.
Prof. Madhur Anand, director of the Global Ecological Change and Sustainability lab, said:
“This could be similar, at least in principle, to how greenhouse gas emissions are increasingly being coordinated internationally to address another major global problem: climate change.”
