Earth Policy Institute: Rising meat consumption drains grain harvest
The future growing of world's population will put a lot of pressure on food production as to answer for its increasing demand. However, the food demand will not just increase as will change its current pattern, given the changes world's population will undergo over the next decades will have a significant impact on the profile of the average diets around the world. In other words, it means that a higher than today's proportion of the grain production will be shifted from human consumption straight into animal production.
This topic is exactly what Earth Policy Institute's researchers address in a very interesting article, "Rising Meat Consumption Takes Big Bite out of Grain Harvest," made available through its website.
