It may be delicious, but the evidence is accumulating that meat, particularly red meat, is just a disaster for the environment – and not so great for human beings, too.
By 2050, scientists forecast that emissions from agriculture alone will account for how much carbon dioxide the world can use to avoid catastrophic global warming. It already accounts for one-third of emissions today – and half of that comes from livestock.
That's a driving reason why members of a United Nations panel last month urged its environmental assembly to consider recommending a tax on meat producers and sellers. By raising the cost of buying meat, it would ultimately aim to reduce production and demand for it.
Maarten Hajer, professor at the Netherlands' Utrecht University, led the environment and food report that recommended the meat tax.
Never miss a local story.
"All of the harmful effects on the environment and on health needs to be priced into food products," said Hajer, who is a member of U.N.'s International Resource Panel, which comprises 34 top scientists and 30 governments. "I think it is extremely urgent."
But, he added, "Food is very political."
In countries where meat is a cultural mainstay and income inequality already breeds a lack of food access, it could be a difficult argument. Taxing sugary drinks this month in Philadelphia caused an uproar among lobbyists, some groups representing the poor and even Bernie Sanders, who argued that the tax was regressive. The response to limiting meat, which is certainly more beneficial to a diet than soda pop, could be mutinous.
But, governments must soon move to limit major carbon producers, Hajer said. Food companies will naturally be part of that.
The idea of a meat tax has developed over the past 25 years as a "completely obvious" measure to economists and environmentalists, Hajer said, as knowledge of the environmental toll of meat emerged.
Agriculture consumes 80 percent of water in the United States. For a kilogram of red meat, you need considerably more water than for plant products.
Governments are starting to take notice. China, which consumes half of the world's pork and more than a quarter of its overall meat, announced new dietary guidelines last week that advise the average citizen to reduce meat consumption by half. That country's meat consumption has increased nearly five-fold since 1982, even though their population has only increased by 30 percent during that time.
Denmark went a little further in May. The Danish government is considering a recommendation from its ethics council that all red meats should be taxed. Red meat accounts for 10 percent of all greenhouse gas emissions, and the council argued that Danes were "ethically obliged" to reduce their consumption.
"For a response to climate-damaging food to be effective, while also contributing to raise awareness of the challenge of climate change, it must be shared," council spokesman Mickey Gjerris said last month.
Phasing out meat and simply eating less would knock down agricultural carbon dioxide emissions considerably — particularly in developed, meat-loving countries.
Laura Wellesley, a research associate at international policy institute Chatham House, said she thinks a global tax could be achieved in the next 20 years. She has studied attitudes about meat consumption among the four most carnivorous countries: China; the United States; Britain and Brazil.
Meat production contributes an estimated 14.5 percent to annual greenhouse gas emissions. That's more than emissions from every car, train, ship and airplane combined.
Countries such as the Czech Republic and Poland have dramatically reduced their agricultural carbon output, as much as a half. But countries that are expanding their meat-lovers' impulses are doing so at much larger jumps. Brazil’s carbon output from food production has increased by 47 percent from 2000 to 2012 — that’s an increase of 150 million tons of carbon dioxide. In China, a 35-percent jump from 1994 to 2005 means 220 million more tons of carbon dioxide. So, Estonia’s 58-percent cut from 2000 to 2012, while commendable, is less than 2,000 tons.
Meat production contributes an estimated 14.5 percent to annual greenhouse gas emissions. That's more than emissions from every car, train, ship and airplane combined. Of that, 65 percent is enteric fermentation (or, cow, sheep and goat farting) and manure, according to a 2014 Chatham House analysis. Feed constitutes one-fifth of that, followed by land-use change, energy use and post-farm activities.
The methane produced by cattle digestion alone is what leads many researchers to call for a reduction. Following carbon dioxide, methane is the second most prevalent greenhouse gas in the United States. A third of that overall is from cattle digestive processes.
On the whole, pigs and poultry contribute 10 percent of total livestock emissions. The rest is cattle, buffalo, sheep and goats – but mostly cows.
There are loads of countries with malnutrition, as opposed to America’s obesity problem. But Wellesley said reducing meat consumption was equally important to boosting meat access to the world’s poorest in ensuring Earth is sustainable for human habitation.
Further, a meat tax could help establish healthy, flexitarian diets that could be consumed by everyone. In the United States and Britian, people eat three to four times the healthy level for meat. Americans ate 120 pounds of meat in 2009, compared with four pounds in Bangladesh. We could be in trouble if those in populous, economic centers, such as China and Brazil, act like the West. China is a "grave concern" to experts, Hajer said.
Along with a tax, a meat cutback could be achieved by making plant-based diets more appealing and less expensive. People in the West often think that vegetarianism is a diet for wealthier folks, Wellesley said.
