This just makes me sad...

CAMBRIDGE, Mass., Oct. 29 (UPI) -- Two-thirds of the plants writer Henry David Thoreau chronicled at Walden Pond in Massachusetts have disappeared due to global warming, a U.S. study contends. The Harvard University report said some of the hardest-hit plants include lilies, orchids, violets, roses and dogwoods. Plants that have thrived in the warmer temperatures include mustards, knotweeds and various non-native species.

"Some plants around Walden Pond have been quite resilient in the face of climate change, while others have fared far worse. Closely related species that are not able to adjust their flowering times in the face of rising temperatures are decreasing in abundance," Charles C. Davis, assistant professor of organismic and evolutionary biology in Harvard's Faculty of Arts and Sciences, said Monday in a news release.

The report said about 27 percent of all species Thoreau recorded in the 1850s around Walden Pond in Concord, Mass., are now locally extinct and another 36 percent are so sparse extinction may be imminent.

One of the arguments most frequently employed by those who want to delay action to stop global warming – whatever their ultimate motives may be for arguing against solving the most urgent environmental crisis of our time – is that implementing the solutions will cost too much money. As gas prices soared higher and higher this argument resonated with a lot of folks, hence there was broad support for opening our coasts to more drilling – even after offshore drilling had been thoroughly discredited as a means for making us more energy independent or lowering gas prices.

The reality is that we can’t afford not to implement solutions like much higher fuel efficiency standards, strict caps on emissions, and drastically increased investment in renewable energy. These are real solutions that will be good for the whole planet, not dangerous distractions that are only good for oil companies’ bottom lines. But given the tough economic times we're living in, the "it will cost too much" argument might gain even more traction -- except that it's completely untrue. And there is new data to prove it:

California’s energy-efficiency policies created nearly 1.5 million jobs from 1977 to 2007, while eliminating fewer than 25,000, according to a study to be released Monday.

The study, conducted by David Roland-Holst, an economist at the Center for Energy, Resources and Economic Sustainability at the University of California, Berkeley, found that while the state’s policies lowered employee compensation in the electric power industry by an estimated $1.6 billion over that period, it improved compensation in the state over all by $44.6 billion.

We must do away with business as usual, and start building the green economy of the future. If we have any future as a species, this transition isn’t just necessary but downright inevitable. We simply can’t drill or mine or dig our way to a sustainable future. Sure, that means that a lot of companies that are making a killing now will either have to change their business model or become obsolete in the marketplace as the cost for them to do business outstrips what people are willing to pay for their goods and services. But it will also mean a healthy planet for future generations and a healthy, sustainable economy as well.

After all, the market turmoil we’ve experienced recently points up the drastic need for a new economic model in this country, and green has always been Wall St.’s favorite color…
