Eat Less, Save The World

800px-L%E9gumes_01.jpg Yup, it's that simple. Nineteen percent of total energy used in the US is tied to producing and distributing food. Too much food. Three times more than we actually need.

Cornell researchers suggest we eat less. The average American consumes 3,747 calories a day. That's 1200-1500 calories more than recommended. It's the reason we're fat and unhealthy, while our planet is lean and unhealthy.

The problem is that American diets are larded in animals and in junk food. Both use more energy to produce than healthful staples like potatoes, rice, fruits, and veggies.

By eating less junk and less meat, the average American would have a massive impact on fuel consumption and his/her health.

The authors suggest moving towards more traditional, organic farming methods for meat and dairy. They suggest crop farmers reduce pesticides and use more manure, cover crops, and crop rotations for better energy efficiency.

Changing the way we process, package and distribute food would help too. Although apparently the single most dramatic improvement in energy use would come from you and me consuming less processed foods. On average, American food travels 1,500 miles before it gets eaten.

Try the Modern Commandments: 1) Buy local. 2) Support organic and sustainable farms. (Stop whinging about the price, you're going to buy and eat less.) 3) Eat mindfully and savor every nourishing bite.

Horse Virus Spreading to Humans

Horses.london.750pix.jpg Heads-up on new developments on a new disease. Australia's biggest outbreak yet of the highly virulent Hendra virus is underway. The disease is transmitted from fruit bats to horses and from horses to humans.

It was identified in 1994—the last year there was a major outbreak. One human trainer and 14 horses died then, reports the Sydney Morning Herald. A second infected person recovered.

Now changes in symptoms in Queensland horses are suggesting a new strain. Perhaps one capable of human-to-human transmission.

New Scientist reports that two veterinary workers became infected roughly four weeks ago and remain hospitalized. Fifty more people who may have had contact with horses will undergo a second set of tests.

So far this year at least seven horses are infected. Five have died. Thirty-six more will be tested for a second time tomorrow.

The classic symptom of Hendra virus in a horse is severely labored breathing, frothy nasal discharge and swollen muzzle. The animals often die within days.

But this year's horses are suffering from neurological symptoms, including paralysis and loss of balance.

Human symptoms include a severe flu-like illness, headache, high fever, and drowsiness, which can progress to pneumonia, convulsions, or coma.

The Hendra virus has not been identified outside of Australia. Every outbreak since the first has been successfully contained to only one horse. Between 1994 and now, one other person was infected and survived. Though, confusingly, the US Centers for Disease Control reports that two out of three human infections prior to this year were fatal.

Bad Air Killing Eastern US

800px-Gavin_Plant.JPG Thinks it's just China? Well, every major ecosystem type in the eastern US is being degraded by air pollution. That's right: Adirondack forests, Shenandoah streams, Appalachian wetlands, and the Chesapeake Bay, to name a few.

A new report [pdf] is the first to analyze the combined effects of four air pollutants across a broad range of habitat types.

Most studies focus on one pollutant. And why not? Things always look so much better that way.

But the sulfur, nitrogen, mercury, and ground-level ozone that are released into the air from smokestacks, tailpipes, and agricultural operations fall back to Earth sooner or later. Ooops.

And because the eastern U.S. is downwind from gynormous pollution sources, it receives the highest levels of deposited air pollution anywhere in North America.

That's bad news for wildlife, forests, soil, water, and, guess what?, economies.

Beijing Spectators Risk Heart Attacks

beijing200.jpgResearchers at Northwestern University warn that pollution in Beijing is so extreme that it could trigger cardiac arrest and strokes in spectators and athletes.

Advice from the docs:

Stay indoors during traffic rush-hour periods. "Indoor air pollution levels are always much lower than outdoor, so staying inside will limit your exposure," Budinger said. He cautioned that Beijing's definition of mild pollution would be a pollution alert day in the U.S.

So that's all good advice for the millions who will be descending upon Beijing for a few weeks, but what about the people who actually live there?

Oh yeah, them: The 750,000 Chinese people that die prematurely from pollution every year—and that the Chinese government doesn't want you to know about. Are they just supposed to stay inside all day every day?

For a good overview of some of the emergency measures Beijing officials have taken to prepare for the Olympics, go here. Hope they keep it up after the party ends. For everyone's sake.

Commemorating Bush's Sh*t

263388397_6feb4ae850.jpg My favorite news of the day. And one reason my heart will always be in San Francisco.

A measure has qualified for San Francisco's November ballot renaming the Oceanside Water Pollution Control Plant the George W. Bush Sewage Plant.

In recognitionof the crap Bush left behind in Iraq. And everywhere.

A quagmire named for the Begetter-of-all-Quagmires.

The Blue Marble Gets a Moon

And we get to see it in orbit around the Earth. Thanks to NASA's Epoxi spacecraft, en route to Comet Hartley 2 in 2010. The film was shot from 31 million miles away. An alien's p.o.v.

Such a pretty world. Why don't we take better care of it?

How Long Will You Live? Depends Where You Live

The American Human Development Project's new report measures the well being of US citizens based on education, health, and income. Unsurprisingly, being an American is much better for some than others.

Of the ten states with the highest median earnings, six are in the Northeast while the rest are just south of there. A whopping 46% of Texas' 29th District (East Houston) never graduated from high school, compared to a drop out rate of only 5% in California's 30th District, which includes Beverly Hills and Malibu.

How well off are you? Test yourself here. Want more? Watch this.

The report may be telling us what some of us already know about our abysmal health care system—that we spend more per person than any other nation only to die younger than basically all of Western Europe—but when the life expectancy of residents in Kentucky's Fifth District is 73 years (same as our national average was in 1978), hard numbers are still sobering.

LEDs Just Got Brighter

800px-Verschiedene_LEDs.jpg

Light-emitting diodes, or LEDs, are four times more efficient than incandescent lights and greener than compact fluorescent bulbs (think: mercury). They also last up to 15 years before burning out.

So why aren't they everywhere?

Because they're expensive—created on a pricey layer of sapphire.

Until now. Purdue University researchers report a novel technique using cheap metal-coated silicon wafers to make LEDs.

Cheaper is better. Widespread LED use could cut electricity consumption by 10 percent.

That could help us heed Al Gore's call to produce all global-warming-free electricity by 2018.

The LED findings appear this month in Applied Physics Letters, journal of the American Institute of Physics.

LA's Lean, Green, Dating Machines

purplecars.jpg

Leave it to LA to find a way to combine efficiency, sex, and eco-street cred. In the city of instant gratification, there's now an easy way to determine if that cute guy at the gym will build a LEED-rated home with you: green speed dating!

Jenean Smith, founder of the Green Speed Dating website, came up with the idea while brainstorming ways to raise money to install solar panels at a rural school in Nicaragua. "One day—I have no idea why—I said, you know what the world really needs? Green speed dating!" She set up an event in Santa Monica, where for $20 participants could spend three minutes on green mini-dates. Eco-conscious Angelenos couldn't get enough. "There's all these green singles' sites that don't have enough people on them, and there's regular speed-dating where you don't know who you're going to meet," says Smith. "People liked that this was a green event for a good cause."

And how did the LA speed-daters evaluate their potential partners' green-ness? By asking what they drove, of course! One lucky guy narrowly escaped having to admit he owned an SUV; another found his bicyling habit made him a little too green for most dates. NPR caught some of the oh-so-awkward car convos; listen yourself here.

Okay, okay, so only in LA would cars be the focus of a green dating event. (To each his own: Portland, OR offers bicycle speed dating.) But the cause is indeed worthy, and word of the site is spreading fast. California readers take note: This could be your summer of green love.

African-Americans Genetically Prone to HIV, AIDS

New research shows that Africans and African-Americans bear a gene variant that helps protect them from malaria, but also makes them more vulnerable to HIV infection. The variant increases susceptability to HIV by 40 percent, says the San Francisco Chronicle.

The genetic trait is found in 90 percent of Africans and 60 percent of African-Americans. Thus far, it has protected against malaria by disabling a protein that some strains of malaria use to enter red blood cells. However, that same protein that's disabled in Africans to prevent malaria can actually protect against HIV by soaking up virus cells before they can invade white blood cells. With this sponge-like protein disabled, Africans lose a key pre-infection barrier.

This finding helps explain, in part, the high HIV infection rates among Sub-Saharan Africans and Americans of African descent. On the flipside, there is a genetic variant among people of Northern European heritage that actually makes them immune to HIV infection. Scientists think the mutation was passed down by ancestors who survived the Black Plague. In one test, a man's blood was exposed to 3,000 times the amount of HIV needed to infect a cell, but infection still didn't occur. The HIV virus simply had no gateway of entry.

Both the European and African genetic traits are currently being studied to see if they can shed light on a cure to HIV.
