Methane emissions are a big deal!

Cows eating

Rising methane levels may be thwarting climate change efforts. A 2017 study attributes about half of the increase to cows and other ruminant livestock which produce methane as they digest food.

Those microbes produce methane as their waste, which wafts out of both ends of cows. The manure that cattle and other grazers produce is also a site for microbes to do their business, producing even more methane. Now consider that there are 1.4 billion cattle in the world. You can see why so much of the methane being produced is from livestock.

“Methane emissions are a big deal. About a sixth of the warming that we’ve had since the start of the Industrial Revolution has been caused by methane,” said  Stanford University professor Rob Jackson, who chairs the international emission tracking organization known as the Global Carbon Project.

Methane is a far more powerful greenhouse gas than carbon dioxide. According to the U.S. Environmental Protection Agency, a molecule of methane will cause 28-36 times more warming than a molecule of carbon dioxide over a 100-year period. Recent data shows that methane concentrations in the atmosphere have risen from about 1,775 parts per billion in 2006 to 1,850 parts per billion in 2017.

So, one way to reduce that is to just stop eating beef, right? That’s what researchers near and far believe, including Paul West at the University of Minnesota.

“As an individual, one of the biggest effects that we can have [to reduce greenhouse gas emissions from agriculture] is changing what we’re eating to eating a smaller amount of beef,” said West.

Why stop there? we ask.  To have the greatest impact, we all need to cut out animal products from our diets as quickly as possible. We can’t afford to only take small steps anymore.

It’s worse than we thought. A new study showed that livestock cause the emission of even more methane than previously thought. Methane is a greenhouse gas 30 times more powerful at warming the atmosphere than carbon dioxide. Previous estimates of the global livestock industry’s methane production had been underestimating their total output, according to a new study by the Joint Global Change Research Institute.

Grass-Fed Beef – bad for us and for the planet

Recently, some people have been touting grass-fed beef as eliminating all the problems associated with meat, or as an equivalent alternative to going vegetarian. Don’t fall for it. Grass-fed beef is still bad for us, the environment and, of course, the cows.

Let’s take a look and see what some leading veg-authors have to say on the subject and then make a few observations of our own. Read more

The High Price of Pork

transport pigWhen it comes to pork, there’s a high price to be paid by the workers, by the environment, and perhaps worst of all, by the pigs themselves. The scale of the problem is enormous. We raise 120 million pigs each year in the US, and many millions more are raised around the world.

The environment pays a high price for concentrated factory-style pig farming. Factory pig farms produce huge amounts of manure – much more than can be used as fertilizer. This manure is stored in lagoons that can leak or break open after a good rain, and cause massive amounts of water pollution as the runoff enters the lakes and streams. This results in massive fish kills and food chain disruption. Methane, a greenhouse gas much more damaging than carbon dioxide, is given off from these lagoons, contributing to global warming, and the intense smell reduces the air quality in the surrounding neighborhood to an often unbearable degree.
