To fix global warming, how about a meat tax?
Many people think with either their wallets or their stomachs. Taking advantage of that can be used to reduce greenhouse gas emissions.
A tax on meat and milk would likely mean we'd buy less of the foods that contribute to climate change. And that's good for the environment, said a study published in the journal Climate Change.
"This tax is not at all a matter of forcing people to become vegetarians but merely moving toward a slightly more climate-smart diet," said one of the study's authors, Stefan Wirsenius of the University of Gothenburg, Sweden, in a press release.
Tacking about $82 onto the cost of beef for every “ton of carbon dioxide equivalent” would reduce Europe's beef consumption by 15 percent. By taxing all meats and milk, Europe's greenhouse gas emissions would be reduced by about 7 percent, according to the study.
“A ton of carbon dioxide equivalent” is the amount of a greenhouse gas needed to equal the heat-trapping power of one ton of carbon dioxide.
The greenhouse gas produced by cattle is methane, a gas 20 times more effective than carbon dioxide at trapping heat. Cows produce methane in their stomachs. The gas then exits the cow through both ends, mostly as belches, but some as flatulence.
Many cattle are fed on corn and other fodder fertilized with nitrogen. Some of that fertilizer is broken down by soil bacteria and turned into nitrous oxide, another greenhouse gas. Discovery News recently reported on farming methods that can reduce the amount of nitrous oxide produced.
