Pombo and mercury

So, last week, the GOP leadership of the House Resources Committee -- in particular, Richard Pombo (R-Calif.) -- released a report (PDF) claiming that mercury has not been linked to deleterious effects on human health, and that most mercury in the U.S. environment comes from natural sources.

The science overwhelmingly contradicts Pombo. Amanda touched on this in the latest Muckraker. Today, Chris Mooney delves further into the details, in this column and this follow-up on his blog. To summarize: A substantial portion of the mercury load in the U.S. environment comes from coal-fired power plants, and mercury stunts children's neurological development. (Mooney also points to a new study (PDF) claiming that mercury-driven diminishment of child IQ costs the U.S. some $8.7 billion in lost productivity every year.) Fetuses are particularly at risk, which is why dozens of states advise pregnant mothers to avoid several kinds of fish. To claim otherwise, Pombo has to distort research by the EPA and the National Academy of Sciences and draw heavily from industry and conservative think tanks.

It's hard to know what to say about this. It isn't a "values" issue like, say, stem cells or family planning. The modern right has distorted science on those topics plenty, but at least in those cases they are defending deeply held religious or moral views. At least there's some sort of principle involved, however risible the methods.

But there's no principle here. No principle, and no legitimate scientific doubt. It's simply an attempt by national legislators to cloud public debate on behalf of one of America's biggest polluters (and GOP contributors) -- at the expense of unborn children. I don't really go in for the overstatement that characterizes many public environmental campaigns, but this does seem a pretty clear case of choosing money over children's health. It isn't the first time, but it is particularly brazen and transparent.

Oxymora, Actually

WC stuff

Another week, another Sustainability Sunday on Worldchanging. Joel Makower brings intriguing news of the Solar High-Impact National Energy (SHINE) Project, "an ambitious and aggressive, three-pronged initiative to make solar both cost-competitive and a significant part of America's energy mix within 10 years." SHINE will be officially released tomorrow, and I'll blog more on it then, but Makower offers a nice preview. Green Car Congress' Mike Millikin brings word that the auto companies realize that the enormous growth of the global automobile market is unsustainable with current technology, and provides a nice, concise roundup of the alternatives on offer (hydrogen, hybrids, etc.).

Speaking of WC, sounds like they got some new funding, new partners, and new plans. Congrats!

100 Least Wanted

What do invasive plants and animals have to do with homeland security? The March 2005 issue of National Geographic reports that "terrorists could use invasives as weapons to 'disrupt and demoralize the U.S. government and its citizens over time.'" This according to Parameters, the U.S. Army College quarterly.

Dubious about the connections between national security and some turtles and weeds? How about economic concerns? "Attack of the Alien Invaders" also reports that "invasives cost the U.S. alone more than 140 billion dollars yearly." For example, the Caribbean tree frog, called a coqui, has "dampened [Hawaii's] 80-million-dollar nursery export business." Lost revenue aside, these little buggers can sound like "a thousand car alarms shrilling in your garden all night." Bummer.

And then there are possible health implications, such as the 2003 case of monkey pox, which jumped from infected African rats to pet prairie dogs to more than 70 people in six states. Luckily, no one died, but this illustrates how alien species can introduce alien viruses and the need for someone to stay on top of this issue. [See Grist's article on conservation medicine in Main Dish.]

But the most obvious concern around invasive species is their impact on local ecosystems. Non-indigenous animals can eat and compete with natives species -- sometimes wiping them out. Invasive plants can choke out natives, which can also impact the animals dependent on those plants as food sources. Check out the Global Invasive Species Database for "100 of the World's Worst Invasive Alien Species," which has been reproduced in the current issue of National Geographic.

Rentable hybrids

Why, it seems like just the other day that Umbra wrote about eco-friendly car renting and car sharing options. Now, here are the johnny-come-latelys at the New York Times with a long story on that exact subject. I am sooo sick of the NYT ripping us off! It's like, dude, get your own stories.

Product service systems

You know what's cool? Product service systems.

What are product service systems, you ask? How can they revolutionize the way we think about ownership and affluence? How can they dramatically reduce our ecological footprints?

These are good questions. However, I'm too lazy, and it's too Friday, to answer them here. Instead, I'm going to do the bloggy thing and point you to a bunch of stuff you should read. Meet back here for discussion.

• For a long and reasonably comprehensive description of PSS stuff, download this UNEP report (PDF).
• You could browse around the Product Service System Information Network's website.
• You could read this Worldchanging post, which, as is their wont, is packed with further links.
  
  Or, if you find all that stuff too taxing...
  
  
• You could browse through Treehugger's PSS category, replete with fun pictures and snappy descriptions of real-world PSS examples.

I'll write more about PSS some time, when it's not so damn Friday.

Wind

Speaking of Jim Motavalli, he has a nice primer in E Magazine on the history and current challenges of the wind power industry. Good reading.

Doctors, vets, and scientists unite in brave new world of conservation medicine

Mosquitoes have Hawaii all abuzz. Photo: WHO/TDR/Stammers. On an airport runway in Hawaii last fall, a sparrow nearly became a canary. State officials testing captured birds got one positive result for the West Nile virus, which had yet to arrive from the mainland. Hawaii and Alaska remain the only states in the U.S. that haven’t […]

Dam

Hydropower a major greenhouse-gas producer, researchers say Although hydroelectric power is often heralded as a green alternative to fossil fuels like coal, scientists now say that in terms of greenhouse-gas production, hydro projects may be just as damning. Ahem. New research reveals that the initial flooding involved in creating hydroelectric dams releases large amounts of […]

People, People Who Breed People

Better make room — world population to hit 9.1 billion by 2050 There will be 9.1 billion people on this li’l planet of ours by 2050, according to revised U.N. population figures released yesterday. That’s a 40 percent increase from today’s mere (!) 6.5 billion. While population in developed countries is expected to remain largely […]
