Living Downstream links environment and cancer

There was once a village along a river. The people who lived there were very kind. These residents, according to parable, began noticing increasing numbers of drowning people caught in the river’s swift current. And so they went to work devising ever more elaborate technologies to resuscitate them. So preoccupied were these heroic villagers with rescue and treatment that they never thought to look upstreams to see who was pushing the victims in. Living Upstream is a walk up that river. Author, environmentalist and cancer survivor Sandra Steingraber, Ph.D., was raised in a family that seemed prone to cancer. She was diagnosed with bladder cancer at age 20. Her mother was diagnosed with breast cancer when Steingraber was in high school. Her aunt died of the same form of cancer that Sandra had, and many of ther close family members also struggled with the disease. But there is no question that cancer does not run in Steingraber’s genes—she was adopted. Clearly, this family was struggling with toxic influences surrounding them in their daily lives. Living Downstream , first published in 1997, both tells the tale of Steingraber’s ongoing battle against cancer and her life’s work linking the effects of our toxic environment on cancer and our health. A documentary film adaptation of the book coincides with last month’s release of an updated edition of the book, tracking recent scientific revelations in the connection between a healthy environment and human health. Find a public screening of Living Downstream , the movie, or purchase a DVD at LivingDownstream.com , and follow Steingraber’s ongoing search for answers and journey of cleaning our environment of carcinogenic influences in Walking Upstream .

Viable renewable energy storage via giant gravel batteries

Energy sources like the sun and wind have the capacity to provide endless amounts of clean energy if we could only figure a way to properly store them when the sun isn’t shining and the wind isn’t blowing. A team of engineers from Cambridge University think they might have a solution: a giant battery that can store energy using gravel. Elevating the idiom “you’ve got rocks in your head” to a whole new level, these scientists hope to solve the sustainable issue plaguing renewables . About his battery Jonathan Howe, founder of Isentropic states that: “If you bolt this to a wind farm, you could store the intermittent and relatively erratic energy and give it back in a reliable and controlled manner.” Howe in order to prove his theories is designing and constructing a small pilot plant that could store 16MWh at full capacity, this could be enough energy to serve the electrical needs of thousands of homes. WorldChanging , in an article, describes how two properly outfitted silos of gravel 7 meters tall and 7 meters in diameter would be all that is needed for storage and retrieval of the renewable energy. Surplus renewable energy storage is a looming issue requiring a sustainably elegant solution, Isentropic’s battery may just prove to be one.

The aftermath of a car-free experiment

Kurt Hoelting’s The Circumference of Home is less remarkable as a memoir of the author’s radically car-free year than it is as perspective on his return to “civilization.” A conversation with Hoelting as his book hits the shelves reveals that his take-away may be more practical and far less radical than a year of limiting his movement to a 60-mile radius by bicycle, kayak and foot. “I am using my car again, but a lot less than I did before,” he admits. “I certainly better understand the transportation alternatives, and a much greater willingness to use them. I travel now by bicycle or public transportation whenever it is a reasonable alternative, and my definition of what constitutes a ‘reasonable alternative’ is much enlarged. “It is difficult to make use of alternatives when you don’t know they are there, and especially if you are not open to them to begin with.” The commercial fisherman, wilderness guide and meditation teacher has once again resumed travel outside his immediate home region. “I drive a Prius, so using the most efficient technology available also plays into the fomula in an important way,” he notes. “And when I do use a car, I carpool as much as possible.” “… Apart from a family emergency, I have maintained my commitment to not flying on jets, which are the biggest source of personal carbon emissions for people who travel a lot, dwarfing the emissions from the use of our cars,” he continues. “A single flight to Europe from Seattle, for example, is responsible for roughly the equivalent emissions (per passenger) or driving an SUV for six months, or a hybrid car for a full year. When I travel to Alaska now for my summer guiding season with Inside Passages, I take the ferry from Bellingham both ways rather than flying. When I travel east, I take the train and use the time for work en route. It is not a trip I can realistically take very often, so I don’t travel outside the region as much as before, and I try to cluster my engagements when I do.” Ultimately, Hoelting reports the changes to his travel patterns were much easier than he had anticipated. The real benefit, he adds, is an increased sense of engagement and belonging within his own home region —”an extraordinary opportunity to wake up to the richness of what is right on the ground beneath our feet.” Glossary: Hybrid fuel technology , Emissions

How sweet the taste of chocolate lip balms

Three things to know about chocolate: Buying organic or fair trade chocolate ensures you are not contributing to child slavery and unfair labor practices . Mainstream chocolate makers haven’t quite caught up with fair trade sourcing yet (although some progress is being made ). You can savor the taste and smell of organic chocolate all day long with Eco Lips’ new line of Dagoba organic chocolate lip balms. I’m not big on flavored lip products, but as an advocate for fair trade and organic chocolate, I felt compelled to report on this important new development (ahem) in the world of chocolate lip balms. Eco Lips , a company known for its certified organic lip balms, has collaborated with Dagoba Organic Chocolate to create three lip balms that soothe your lips with organic ingredients while soothing your senses with the taste and smell of chocolate. Organic cocoa in your lip balm? If that sounds a little odd to you, you’re not alone. The new balms are a little too sweet for my own taste, personally—but the rest of my family thinks the review samples we tried are just fine, thank you very much. And there’s no denying these balms moisturize and heal chapped lips like champs. The new line comes in three flavors: roseberry (raspberry, rosehips and dark chocolate—my personal favorite and the most chocolatey); mint (a brisk mix of mint, rosemary and dark chocolate); and lavender (lavender, blueberry and dark chocolate). One of them will surely be the balm for your chocolate-craving soul—and lips. (Photo credit: Eco Lips ) Glossary: Organic , Fair trade , Fair wage , Sustainable

Walt Whitman on Nature

“After you have exhausted what there is in business, politics, conviviality, and so on – have found that none of these finally satisfy, or permanently wear – what remains? Nature remains. ” Walt Whitman
