Nice biased environmentalist metaphor, isn’t it?
You know we see these sorts of stories all the time, and because they’re just people using causes to attempt to change our behavior, we don’t pay them the attention they deserve. But, if any of the things associated with what you’re about to read were to become law, suddenly choices and amounts of beef could easily be rationed to “save the planet”. Add a little health care legislation and it’s a lock.
When it comes to global warming, hamburgers are the Hummers of food, scientists say.
Simply switching from steak to salad could cut as much carbon as leaving the car at home a couple days a week.
That’s because beef is such an incredibly inefficient food to produce and cows release so much harmful methane into the atmosphere, said Nathan Pelletier of Dalhousie University in Canada.
Pelletier is one of a growing number of scientists studying the environmental costs of food from field to plate.
By looking at everything from how much grain a cow eats before it is ready for slaughter to the emissions released by manure, they are getting a clearer idea of the true costs of food.
The livestock sector is estimated to account for 18 percent of global greenhouse gas emissions and beef is the biggest culprit.
Even though beef only accounts for 30 percent of meat consumption in the developed world it’s responsible for 78 percent of the emissions, Pelletier said Sunday at a meeting of the American Association for the Advancement of Science.
That’s because a single kilogram of beef produces 16 kilograms carbon dioxide equivalent emissions: four times higher than pork and more than ten times as much as a kilogram of poultry, Pelletier said.
If people were to simply switch from beef to chicken, emissions would be cut by 70 percent, Pelletier said.
Another part of the problem is people are eating far more meat than they need to.
“Meat once was a luxury in our diet,” Pelletier said. “We used to eat it once a week. Now we eat it every day.”
If meat consumption in the developed world was cut from the current level of about 90 kilograms a year to the recommended level of 53 kilograms a year, livestock related emissions would fall by 44 percent.
The way things are going it wouldn’t surprise me one day to see PSAs like the Chik-fil-A commercials saying, “Eat More Chikin” and cut emissions by 70% – it’s the law!
