Were we to eat soya, rather than meat, the clearance of natural vegetation required to supply us with the same amount of protein would decline by 94%. Producing protein from chickens requires three times as much land as protein from soybeans. Pork needs nine times, beef 32 times.
A recent paper in the journal Science of the Total Environment suggests that our consumption of meat is likely to be “the leading cause of modern species extinctions”. Not only is livestock farming the major reason for habitat destruction and the killing of predators, but its waste products are overwhelming the world’s capacity to absorb them. Factory farms in the US generate 13 times as much sewage as the human population. The dairy farms in Tulare county, California produce five times as much as New York City.
Freshwater life is being wiped out across the world by farm manure. In England, as I reported last week, the system designed to protect us from the tide of crap has comprehensively broken down. Dead zones now extend from many coasts, as farm sewage erases ocean life across thousands of square kilometres.
