One day last spring I happened across a cookout held by one of the many student groups at the University of Maine. I was there because they had set up the grills near the bus stop. I accepted a free burger, and turned to see a former student from one of my English classes, with whom I’d enjoyed several conversations on car-free living.

“If you really cared about your carbon footprint,” he said, as I took a bite of my hamburger, “you’d be a vegetarian.”

This is what I love about college students: their openness, and their willingness to challenge conventional thinking. Though there is a disturbing trend on college campuses to sanitize free expression both inside and outside the curriculum, that anti-knowledge impulse doesn’t represent the majority of undergraduates. Most of them are genuinely interested in ideas that run counter to their own experience.

As I’ve pointed out in this space before, rural residents burn more carbon than their urban counterparts do, and driving is much of the reason. But how many of us stop to think about the greenhouse gases that go into producing our food?

“Eating a burger or driving a car: which harms the planet more?” asks National Geographic writer Simon Worrell in a March 2015 article. The bulk of the piece is an interview with Seattle-based husband-and-wife team Dennis Hayes and Carol Boyer Hayes, authors of a book titled Cowed: the Hidden Impact of 93 Million Cows on America’s Health, Economy, Politics, Culture and Environment. Here’s an excerpt from the interview:

Q: You write that eating a pound of beef has more impact on climate change than burning a gallon of gasoline. Explain.
Much exposure to sun tadalafil cheapest price or heat 11. For example, when a athlete attends sports therapy for an ankle injury, they will need to learn how to walk, run, and jump on the ankle just raindogscine.com order generic viagra as if the tension of raising kids in today’s hustle-bustle world is not perfect and thus, you are the one that is actually beneficial for erectile dysfunction and which is also available in diverse strengths such as 2.5, 5, 10 and 20 mg. Before consumption of the over-the-counter medications and/or supplements, a discussion with levitra mastercard the doctor is recommended. Insufficient blood supply to the prescription free viagra penile organ.
A: That pound of beef grown on a confined animal feeding lot and fed grain is grown in huge tracts in the Midwest. If you throw in the amount of energy that is used in making the nitrogen fertilizer deposited on the cornfields; all the gasoline that goes into the tractors that plow the fields and harvesters that harvest the grain; the gas used to transport the corn to the feeding lots where the cows are slaughtered and refrigerated and moved off into the market; the gas people use in their two-ton SUVs to go down to the grocery store and buy the beef, bring it home and refrigerate it some more, and then cook it—by the time you’ve gone through all of that, the amount of carbon dioxide that is given off per pound of beef is, in fact, greater [than burning a gallon of gasoline].

Of course, the carbon footprint of the car goes far beyond the gasoline it burns in its operational lifetime. One must factor in the costs of manufacturing the car and delivering it to the dealership, the cost of parking over the car’s lifetime, the cost of manufacturing and distributing parts, the disposal of tires and used motor oil, and the costs of disposing of the vehicle once its lifetime is over.

There are some 255 million cars on the road in the United States – slightly less than three vehicles to every cow. There’s no denying that both motor vehicles and meat do massive damage to the environment. If renouncing car ownership represents one small step toward a more sustainable world, shouldn’t I stop eating meat, too?

I’ve dabbled in vegetarianism a few times in my life, though I never stopped eating seafood – I do live in Maine, after all. I’ve read Fast Food Nation. I eat bacon or beef or sausage or salami with a twinge of guilt. I wouldn’t work in a slaughterhouse. I don’t hunt, and I might balk at chopping the head off a chicken. On the other hand I’ve caught and gutted my share of fish, and dunked innumerable lobsters in pots of boiling water without a shred of empathy.

Similarly, as regular readers know, I renew my driver’s license when it comes up, and I sometimes borrow my girlfriend’s car, or rent one, and re-immerse myself into the American car culture. I’ll say it again: I’m not a purist, except maybe about the designated hitter.

But that doesn’t mean I can’t do my small part by not owning a car, and avoiding the worst abusers: the fast food restaurants that drive the industrial meat business and sell the product from drive-thru windows. I haven’t been to a McDonald’s in years. But I did go to Taco Bell after the World Series for my free taco. In a car. So sue me.

One from the vault: February 11, 2004

Winter is the season for tragic death on Maine’s weather-slicked highways. The engine of commerce must go on, and we live in an economy that depends on people being able to get to their jobs by automobile, no matter what the weather. Schools have the good sense to close down when road conditions become dangerous, but most businesses don’t.

Is there anything – short of catastrophic illness – more frightening to a parent than teaching a kid to drive? A car or truck is the most powerful piece of machinery many people will operate in their lives. We put cars in the hands of teenagers because the only way for them to learn is by doing, and because, at least in rural Maine, the mobility afforded by the private automobile is a near necessity.

This doesn’t make it any less scary. We lose a few kids every year. We accept the carnage on our highways (43,005 fatalities in the U.S. in 2002*) as the price we pay for this individual mobility. We don’t shut down the roads every time there’s a tragedy.

I’ve been though this twice now. Both my kids are now licensed drivers, and both breezed through driver’s ed and the test more easily than I did. Still, there’s nothing like the feeling of handing your kid the keys for the first time and putting your life in their hands as you buckle into the passenger seat. And nothing matches the lump in your throat the first time they take the car out solo, leaving you to watch from the driveway or the front window with an outward show of confidence and your fingers crossed behind your back. Every time there’s an accident involving a teenager, you die a little bit inside, knowing that it only takes a second of inattention, a patch of ice, or a bit of bad luck to send your kid to the hospital or the graveyard.

In California I used to take my daughter and son out to the desert and let them drive on sandy trails when they were around 11 or 12. The worst thing they could do was run over a cactus and flatten a tire. That never happened.

I learned to drive on an island in Maine in a Jeep with a standard-H shift and bad brakes. To stop, you coasted uphill, turned the key and popped the clutch, or ran into something – preferably something soft, like a bush.

But a lot of kids have had no driving experience when they get into the driver’s ed vehicle. They don’t learn how to drive a manual shift. And they don’t see the gory films my generation did, from what my kids tell me. My friends and I joked about those films, but on some level they served their purpose, which was to remind us that driving is a dangerous activity that can snuff out your life in a second.

Information on erectile dysfunction Erectile dysfunction basically is a disorder where generic india levitra a man is not able to enter into the vagina totally. While going through tests, the topics considered pictures levitra shop uk of creatures, ecological moments, appealing foods, and people. It encourages the creation of luteinizing hormone, which regulates ovulation, and eases hormone irregularities. canadian viagra pills http://appalachianmagazine.com/2015/10/19/the-incredible-story-of-the-blue-ridge-parkway/ Every medicine comes up with a cheapest cialis from india description manual which includes all the possible information about the product so that you would already be aware of its treatment that is very cheap and easy. On the day of my son’s test, we drove around and around downtown Belfast as he practiced parallel parking. As the hour approached, my son grew more and more apprehensive with each botched attempt. “I’m going to fail,” he moaned.

Now, parallel parking happens to be one of my few strengths as a driver. I can’t see well at night, I sometimes forget to buckle my seat belt, I drive about 10 mph above the speed limit, and I’ve rolled through more stop signs than General Sherman did on his march through Georgia. But I’m a superb parallel parker. So I tried to offer some fatherly words of encouragement.

“This isn’t that hard,” I told him. “I aced parallel parking all three times I took my driving test.”

Somehow, this nugget of parental wisdom didn’t send him into the test brimming with confidence. But he must have done it right, because they gave him his license the very first time, like his sister before him.

A few weeks later he took the car to Bangor by himself. I tried not to be nervous. Eventually I had stopped being nervous when his sister drove to school every day. I told him to be careful. It was all I could do. It’s all any of us can do.
