As tax season ramps up, we’re bound to hear proposals aimed at making the revenue system simpler and more efficient. A perennial is the “sin tax.” Rather than tax earnings—when we really want people to earn money—why not tax things we don’t want people to do? Add duties to cigarettes, alcohol, and carbon dioxide to slow people’s smoking, drinking, and polluting, and you’ll do them and the world a favor while raising revenue for schools, hospitals, and roads. But why stop there? It’s time to add one more sin to the list of habits that should be taxed: excessive meat consumption.
When it comes to gorging on meat, Americans remain at the top of the global league tables. U.S. consumption of beef per person has actually declined over the past few decades, from 52 kilograms a year in 1970 to 41 kilograms in 2008. But chicken consumption approximately tripled over that period, to 44 kilograms per person, and overall meat consumption climbed from 105 to 122 kilograms a year—considerably more than the average personal weight (although some of that meat is thrown away or eaten by pets). By comparison, Indians consume less than 5 kilograms of meat per person.
At the other end of the consumption scale, all that meat production also makes for more expensive staple foods for the world’s undernourished. About one-third of the world’s cropland is given over to growing feed for animals. Including pastureland, livestock production occupies 30 percent of the land surface of the planet. Some of that land could be used instead to cultivate crops for human consumption. If you are concerned that growing corn for ethanol is raising food prices, you should be even more concerned by the larger impact of factory livestock farming.
Greater meat production also has negative environmental effects. Livestock accounts for about 8 percent of global human water use (the proportion is a little higher in the U.S.) Wheat takes about 1,000 to 2,000 cubic meters of water per ton of crop; rice takes approximately double that. Taking into account the water demands of feedstock, cattle take between 13,000 and 20,000 cubic meters per ton of beef (although chicken does considerably better at around 4,000 cubic meters per ton). Land-based meat production is also a big factor behind declining fisheries worldwide. Millions of tons of fish each year are crushed into fish oil and dry feed to be fed to farmed fish as well as to pigs and chickens. And the effluence those animals produce creates “dead zones” in rivers and coastal areas.
