Meat production is about ten times more water-intensive than plant-based calories and proteins, with one kilogram of beef, for example, requiring 15,415 liters of water. It is also an inefficient way of generating food; up to 30 crop calories are needed to produce one meat calorie.
肉类生产消耗的水资源约为植物热量及蛋白质的十倍以上，比方说生产一公斤牛肉需要消耗15，415升水。这种粮食生产方式也十分低效；需要消耗30植物卡路里才能生产出1肉类卡路里。
