Just two years after being leveled by a tornado, Greensburg, a tiny town in the middle of Kansas has become a model for green rebuilding.

Nearly 95% of the town's homes and other buildings were destroyed by the storm, as seen in this photo, taken a week after the tornado hit.

The green rebuilding of Greensburg, Kansas cannot be attributed to an unlikely enclave of progressive thinkers in the American heartland. Rather, says Daniel Wallach, (right) founder and Executive Director of Greensburg GreenTown, the fact this has happened in a small, deeply conservative town makes it even more significant.

FEMA (the Federal Emergency Management Agency) was quick to respond to the Kansas tornado that flattened Greensburg, in part to improve their public profile after the Gulf Coast hurricanes. But Wallach says the agency had to be persuaded at length to buy into the green vision that the community shared.

There's an extensive photo gallery of the damange caused by the tornado and the new buildings that have emerged in its wake on one page of the Greensberg GreenTown website. Another page hosts their design competition for eco-friendly homes. "The Chain of Eco-Homes"  has attracted 150 entries, which can be viewed and voted for online. The winnign design will be built as part of the town's ongoing effort to promote itself as "a living science museum" on green consrtruction and muncipal planning.

Global warming has moved from a looming problem to an imminent crisis, warns environmental writer Bill McKibben, and the international campaign to demand action rests on a simple three digit number.

The urgency that underscores the 350 campaign is tied to the newly realized effects of the well-documented one degree increase in the temperature of the world’s oceans. Noted environmental writer Bill McKibben says that until recently, it was believed that was not enough of a difference to trigger the cascading changes that are now being documented.

Even if humankind is successful in tempering the worse effects of global warming, McKibben says it will take generations to bring atmospheric carbon levels back down to 350 or less.

  Bill Mckibben is the author of The End of Nature and numerous other books on environmental issues, including the newly published Bill McKibben Reader. He’ll be talking about the 350 campaign  on Friday, October 2 at Sonoma County Day School in Santa Rosa.

Wave power off the Sonoma County coast is a potentially carbon-free source of electricity, but it faces big questions about environmental impacts and economic viability.

You can read more about the project on the Water Agency's website.The image at right shows one prototype of a low-profile generator which could be deployed in an array of dozens of individual units, as illustrated below, to power a sizable area.

The Sonoma County Water Agency's first informational meeting about the wave power studies was held in Gualala on September 9th. Most of the people there, reports Richard Charter, knew nothing about the project before that meeting.


Two other study projects on the Northern California coast have received permits from the Federal Energy Regulatory Commission (FERC), both issued before the Sonoma County Water Agency's application was approved. Cordell Stillman (left with Water Agency boss Randy Poole) says both sites were sought by PG&E, but other than that, they are quite different in status and approach.

While the entire concept of wave-generated electricity is in its very earliest stages, Richard Charter  (left) observes that it holds some benefits from an environmental perspective, but it is hardly a clear or easy solution to meeting future power needs.

Preserving biological diversity isn’t the only reason for protecting endangered plant species—in some cases, its good for our health, too.

United Plant Savers emerged in the 1990s, primarily in response to the depletion of naturally occurring supplies of popular medicinal herbs, explains Executive Director Lynda LeMole. Until that time, most of them were harvested by hand, in a process known as “wild-crafting.”

While herbal medicine is most commonly associated with the orient, eastern practitioners have long had a keen appreciation for certain medicinal plants from North America, especially American Ginseng, seen being harvested at left.

Commercial cultivation of many medicinal herbs is complicated by the challenges in replicating their natural growing conditions, particularly for those, like American Ginseng, that are found on the forest floor. Even here in Sonoma County, where conditions favor a wide range of crops, many sensitive herbs will not thrive. That's another factor complicating the preservation of the "at risk" herbs on the list below.

There is a full list of botanical sanctuaries (including three  in northern California) among the  resources at the United Plant Savers website.

Lynda LeMole, Executive Director of United Plant Savers, will be the featured speaker tonight at the Science Buzz Café  in their new home at the Youth Annex adjacent to the Sebastopol Community Center, at 7 pm.
