Think the barrels normally used for rainwater harvesting are ugly? You’re not alone: that’s the response University of Akron art education professor Elisa Gargarella heard from friends in response to her own home rain barrel. Rather than put the barrel away, though, Gargarella found inspiration in her friends’ distaste: if people find them ugly, why not make them beautiful?

Sounds like the approach an artist would take, right? Gargarella went a step further, though: as the director of Arts LIFT, an arts apprenticeship program for urban youth, she made beautifying rain barrels the centerpiece of this summer’s program. She also added an environmental education component: the ten teenage apprentices spent time learning about water-use issues, listening to lectures on water conservation, and even taking a tour of the local sewage treatment plant.

GreenTalk Radio host Sean Daily talks to Stephanie Thornton of the EPA about their WaterSense program. Much like the EnergyStar program, WaterSense seeks to help Americans to save water and protect the environment by creating product efficiency standards that manufacturers must meet in order to receive the WaterSense certification label on their products.

Today we are an oil-based civilization, one that is totally dependent on a resource whose production will soon be falling. Since 1981, the quantity of oil extracted has exceeded new discoveries by an ever-widening margin. In 2008, the world pumped 31 billion barrels of oil but discovered fewer than 9 billion barrels of new oil. World reserves of conventional oil are in a free fall, dropping every year.

As I note in my latest book, Plan B 3.0: Mobilizing to Save Civilization, discoveries of conventional oil total roughly 2 trillion barrels, of which 1 trillion have been extracted so far, with another trillion barrels to go. By themselves, however, these numbers miss a central point. As security analyst Michael Klare notes, the first trillion barrels was easy oil, “oil that’s found on shore or near to shore; oil close to the surface and concentrated in large reservoirs; oil produced in friendly, safe, and welcoming places.” The other half, Klare notes, is tough oil, “oil that’s buried far offshore or deep underground; oil scattered in small, hard-to-find reservoirs; oil that must be obtained from unfriendly, politically dangerous, or hazardous places.”

This prospect of peaking oil production has direct consequences for world food security, as modern agriculture depends heavily on the use of fossil fuels. Most tractors use gasoline or diesel fuel. Irrigation pumps use diesel fuel, natural gas, or coal-fired electricity. Fertilizer production is also energy-intensive. Natural gas is used to synthesize the basic ammonia building block in nitrogen fertilizers. The mining, manufacture, and international transport of phosphates and potash all depend on oil.

Still have bottled water as a regular item on the grocery list? Or just pick up the occasional bottle when you’re out? It’s so convenient…

As you probably know, that convenience comes at an environmental and social price: documentaries such as FLOW and Thirst, organizations such as the Sierra Club and Environmental Defense Fund, and even a few of us lowly bloggers, have reported on the costs created by water’s transformation from a freely-available resource to a multi-billion dollar commodity. That bottle of water you buy now contributes to the world’s third-largest industry.

As the earth warms, the melting of the earth’s two massive ice sheets—Antarctica and Greenland—could raise sea level enormously. If the Greenland ice sheet were to melt, it would raise sea level 7 meters (23 feet). Melting of the West Antarctic Ice Sheet would raise sea level 5 meters (16 feet). But even just partial melting of these ice sheets will have a dramatic effect on sea level rise. Senior scientists are noting that the Intergovernmental Panel on Climate Change (IPCC) projections of sea level rise during this century of 18 to 59 centimeters are already obsolete and that a rise of 2 meters during this time is within range.

As I note in Plan B 3.0: Mobilizing to Save Civilization, assessing the prospects for the Greenland ice sheet begins with looking at the warming of the Arctic region. A 2005 study, conducted by the Arctic Climate Impact Assessment (ACIA) team, an international group of 300 scientists, concluded that the Arctic is warming almost twice as fast as the rest of the planet. It found that in the regions surrounding the Arctic, including Alaska, western Canada, and eastern Russia, winter temperatures have already climbed by 3-4 degrees Celsius (4–7 degrees Fahrenheit) over the last half-century.

In testimony before the U.S. Senate Commerce Committee, Sheila Watt-Cloutier, an Inuit speaking on behalf of the 155,000 Inuits who live in Alaska, Canada, Greenland, and the Russian Federation, described their struggle to survive in the fast-changing Arctic climate as “a snapshot of what is happening to the planet.” She called the warming of the Arctic “a defining event in the history of this planet.” Read the rest of this entry »

Lester R. Brown - Earth Policy Institute

In the May issue of Scientific American Lester R. Brown, President of Earth Policy Institute, discusses how food shortages could be the weak link that brings down civilization.

In this feature article, “Could Food Shortages Bring Down Civilization?” Brown notes that the biggest threat to global political stability is the potential for food crises in poor countries to cause government collapse. Those crises are brought on by rising demand and ever worsening environmental degradation.

“In the twentieth century,” Brown says, “dramatic rises in grain prices results from poor harvests. They were event-driven and short-lived. In contrast, the recent escalation in world grain prices is trend-driven, making it unlikely to reverse the rise in food prices without a reversal in the trends themselves.”

Earth Day provides us with an opportunity to both reflect and act on our desire to use the planet’s resources in a sustainable manner. As we’ve noted in numerous posts, water may be the one resource we should focus on more, individually and collectively. No doubt, many of you have water-saving activities planned; a few of you may already be at work installing low-flow shower heads, faucet aerators, or even rain barrels.

Rain water harvesting makes a lot of sense: the initial investment can be quite low (especially if you do it yourself), and your plants love rain water.  Unfortunately, as Rachelle Carson Begley once noted, an awful lot of commercially-available rain barrels are, well, ugly.
