Take a walk
When we walk we stop killing. We take our place in nature and restore our humanity.
There is only one way humans are made to move. They are made to walk. There are many other ways to get around. You can canoe, for instance. Or paraglide. Or jog. But these modes of transportation are not the staple of human mobility. Walking is unavoidable, a necessity for those with two working legs.
The entire scheme of nature, and the human’s place within it, is built around the understanding that humans use their legs to move. It’s a great unspoken assumption. The earth expects humans to walk.
Wildlife expects humans to walk, and it has trouble with other forms of transport. North American drivers kill 1 million animals each day, nearly 12 animals per second. Four hundred million animals are killed by drivers in North America each year. Almost 2 million deer are killed on North American roads yearly.
According to the National Institute for Urban Wildlife and U.S. Fish and Wildlife Service, 50 to 100 million birds are killed each year by vehicles. Research reports that roadkill is a significant factor in the decline of amphibians. Motorized transport dramatically reduces insect populations.
Though humans invented vehicles, we have trouble understanding them, too. The 210 million vehicles on North America’s 4.5 million miles of roads cause 47,000 human deaths a year. But, how many mammals, birds, amphibians and humans would be hurt or killed if humans only walked?
A walker is not likely to “run over” a gopher when she walks. If she waded into a stream, she’s unlikely to step on a fish. All creatures, in this sense, understand walking. Walking is a primal transport, expected by the world’s animals and the land itself, evidence of an ancient arrangement between humans and their world.
Walking serves as a bridge between other humans and other animals. Humans tend to walk between 2 and 5 miles per hour — an average of around 3 miles per hour. Dogs walk at speeds between 2 and 4 miles per hour. Camels walk an average speed of 3 miles per hour. Horses and mules, when walking, operate at speeds of 3 to 4 miles per hour. Elephant walk at 4 miles per hour. The old friendships between humans and some animals partly depend on a shared walking speed. A walking pace is the speed of community.
Though we don’t walk with many other animals, we could. Many other animals share a similar pace: bears, mice, ants, snakes, cats, aardvarks. The ordinary human can keep pace with a puma, a zebra, a rhinoceros or an American president.
Yet, humans are obsessed with the top speeds of each living thing. Many sources announce, for example, that the elk has a top speed of 25 mph. Very few note the walking speed: between 3 and five 5 mph.
As part of that obsession, humans find ways to travel faster every year. Usain Bolt’s recent Olympic sprint averaged 23 mph. When he sprints, he is unique, and alone. When he walks, any walking human can keep pace. Top speed emphasizes difference.
Mechanically assisted types of transport alienate humans from their planet, and from one another. The fastest humans, currently, ride in the space shuttle traveling at 18,685 mph in orbit; 18,685 mph is an unearthly speed. Top speeds separate us from one another and alienate us from the earth. Lower speeds unify us and bind us to our planet.
For those who like speed, there is a price to pay. One cost is tension. The mind, when you drive, is consumed, for the most part in the exercise of managing extra speed, paying attention, watching for potholes and pedestrians. Even jogging requires more attention than walking.
Researchers report that the faster you travel the more tension you experience. A number of studies report, for example, that when speed increases, negative emotions intensify. This factor alone plays a large role in what has been termed “road rage.”
Another cost is a diminished sense of context. When you walk, your field of vision is nearly 180 degrees, 140 degrees of which feeds your awareness. The Optometrists Association of Australia reports that human field of vision “is reduced with increasing speed.” For example, at 62 mph, field of vision contracts to 40 degrees.
Higher speeds cause peripheral vision to “smudge,” which hampers object recognition, and lowers response times. Motorists traveling 25 mph or faster have more difficulty determining whether a pedestrian is ready to cross a street, and in consequence have more difficulty deciding whether they should slow down.
In other words, speed impedes thinking and decision-making. Thought depends on perception, but speed impairs it. Things “come out of nowhere.” Collisions become inevitable. So walk.
Begin. Choose a walk of a reasonable length. Start with once a week. A 5-minute drive from your home, at average city speeds, amounts to a 25-minute walk, one way. Select a quiet route, as thought speaks with a quiet voice. You should be able to hear the sound of your own steps as you walk. Connect it to a light errand of some kind — picking up a quart of milk or meeting someone for joe. Plan some extra time, if you can. It’s great to walk, but walking slowly is delicious. Choose a beautiful day. Dress in layers, so you can adjust your body temperature with your step. Wear comfortable footwear. And walk.
Because walking is a cure. When we walk we take our place in nature. We untie our minds and improve thought. We restore our humanity. So, walk. After all, it’s what we were designed to do.

Farmers’ sand-frac nightmare
Some parts of rural America are being ruined by an unstoppable new mining industry -- and it's spreading
Frac sand piles up at a processing plant in Chippewa Falls, Wis. (Credit: AP/Steve Karnowski) If the world can be seen in a grain of sand, watch out. As Wisconsinites are learning, there’s money (and misery) in sand — and if you’ve got the right kind, an oil company may soon be at your doorstep.
March in Wisconsin used to mean snow on the ground, temperatures so cold that farmers worried about their cows freezing to death. But as I traveled around rural townships and villages in early March to interview people about frac-sand mining, a little-known cousin of hydraulic fracturing or “fracking,” daytime temperatures soared to nearly 80 degrees — bizarre weather that seemed to be sending a meteorological message.

Environmentalists are focused oil and gas, but a bigger carbon disaster may be brewing in the Pacific Northwest
A coal mine owned by Arch Coal Co. (Credit: AP/Matthew Brown) Coal is without question our dirtiest fuel source: When burned, it dumps toxins like mercury and nitrogen oxides into the air and packs an outsize punch when it comes to carbon emissions. Since America has a lot of it, though, we’ve tended to use a lot: Historically, around half our electricity has been generated by coal combustion plants. But as a result of sustained anti-coal activism, low prices for natural gas, and new EPA regulations on power plant emissions, Americans are using a lot less coal than we used to, and the future of the sooty stuff in this country is looking dim. So the U.S. coal industry is pinning its hopes on China. While historically most of our exported coal has gone to Europe, U.S. exports to China increased 176 percent between 2009 and 2010, and that number is likely to keep rising as the Asian market for coal continues to expand. The prospect of shipping coal across the Pacific is even more appealing considering that Western states like Wyoming and Montana have vast coal reserves in the Powder River Basin, one of the largest coal deposits in the world.

Is it ethical to drive stick?
More drivers are buying manual transmissions -- a boon for auto sentimentalists but bad news for the environment
(Credit: cristapper via Shutterstock) Ever since I first watched my dad drive his chocolate brown Datsun 280 ZX back in the early 1980s, I’ve been inculcated to believe that driving — true driving — can only be performed with a stick shift. From that childhood experience, I came to see the manual transmission as a birthright passed down from my grandfather, to my father, and eventually to me via a series of tense, stall-filled lessons when I turned 16. In my case, after ripping apart the transmission one too many times, my dad went barking drill sergeant on me, eventually teaching me that a stick requires a special kind of focus, and that I needed to ease up more slowly on the clutch in order to get into first gear on those damn inclines. Through the experience, I learned to consider my stick-shifting skill a special talent with transcendent value.

An eco-pioneer’s final words
The visionary author of "Ecotopia," who died in April, warns of dark times ahead, but sees a path through the decay
To all brothers and sisters who hold the dream in their hearts of a future world in which humans and all other beings live in harmony and mutual support — a world of sustainability, stability, and confidence. A world something like the one I described, so long ago, in “Ecotopia” and “Ecotopia Emerging.”
As I survey my life, which is coming near its end, I want to set down a few thoughts that might be useful to those coming after. It will soon be time for me to give back to Gaia the nutrients that I have used during a long, busy and happy life. I am not bitter or resentful at the approaching end; I have been one of the extraordinarily lucky ones. So it behooves me here to gather together some thoughts and attitudes that may prove useful in the dark times we are facing: a century or more of exceedingly difficult times.

"Last Call at the Oasis" paints a haunting, even poetic, portrait of the global water crisis. Will anyone listen?
Here’s the short version of humanity’s relationship with water, as delivered by hydrologist Jay Famiglietti in Jessica Yu’s compelling and often gorgeous documentary “Last Call at the Oasis”: “We’re screwed.” Yes, we should all install low-flush toilets and plant gardens that require less watering, but conservation is simply insufficient to cope with a global fresh-water crisis that involves many interlocking factors: overpopulation and overdevelopment, depletion of groundwater, climate change, and widespread contamination.
