Today’s Thursday, so presumably we can all enjoy a hamburger without being made to feel guilty by the virtuous soy-eaters who are saving the planet (thanks Environmental Working Group). But what happens when the weekend is over, Monday morning appears in all it’s miserable beginning-of-the-week glory and we’re choosing lunch? According to many schools, universities, hospitals, retirement complexes and workplaces, Monday is the day when you can make a difference!
Simply by replacing that ham and cheese with a nice alfalfa and hummus wrap, we can all sleep safely knowing that our hummer driving and air-conditioning set at 65 degrees isn’t harming the environment – after all, we went meatless today! So what’s the real impact of Meatless Mondays?
If you believe the hyperbolic text of the EWG’s recently released report, animal agriculture is the root of all environmental evil. Yet buried on page 21 is the admission that animal agriculture only accounts for 4.5% of the US’s carbon footprint. The EPA has a somewhat smaller, but similar figure at 3.1% of total emissions. The original Meatless Mondays claim appears to have been derived from a paper from Carnegie Mellon that concludes:
Shifting less than one day per week’s worth of calories from red meat and dairy products to chicken, ﬁsh, eggs, or a vegetable-based diet achieves more GHG reduction than buying all locally sourced food.
So let’s do the math. Removing poultry and horses from the EPA’s animal agriculture total of 3.1% gives a red meat/dairy impact of 3.05%. Divide that by 7, and the impact of one meatless day per week is equal to 0.44% of the US carbon footprint – and that’s assuming that the US population of 311 million people all adopt this lifestyle change.
0.44% is minuscule. A tiny fraction of the impact that we could make on the carbon footprint. But if we put it in consumer-friendly numbers, it’s like taking 5.7 million cars off the road each year, or planting 4.5 billion trees. Sounds far more compelling now doesn’t it? But how does that compare to the impact of powering the MacBook upon which I’m currently writing this post during a 3 hour cross-country airplane flight, followed by a 90 minute drive home? Not to mention all the other environmentally-damaging actions I’ll execute before the day is out.
In a world where we have a wildly tenuous grasp on the immediate or long-term environmental consequences of the majority of our actions, we really need to assess the environmental impact of simply existing as a human. Forget demonizing specific foods, or pretending that one single action can save the planet – we need to understand and quantify how all our choices have consequences – and act accordingly.
