Our meat eating habits as the reason why people still starve in the world?

"Cattle, pigs, chickens, and turkeys consume 70% of the United States grain crop; feeding these grains to farmed animals is extremely wasteful. In the process of cycling grains through other animals to produce flesh, eggs, and milk, we lose vital nutrients and billions of consumable calories. In The Mathematics of Starvation, Tom Spontelli notes that ranchers cycle 24,000 calories of grain into cattle to retrieve 1500 calories from flesh: a 94% caloric loss. Every time we sink our teeth into a cow’s flesh, we vote to keep sending 6,000 calories of the world’s grain (which could feed a child for 10 days) into a cow’s belly to ultimately retrieve only 375 calories. If we want to feed hungry people, we need to eat grains directly rather than feed vast quantities of grain to cattle. When we cycle grains through cattle we also lose 90% of grain’s protein, 99% of the carbohydrate, and 100% of fiber: We exchange heart-healthy grains for a coronary surprise and a ticket to obesity."
