In South Korea, it’s easy to tell a toned, avid cyclist when you see one. You’ll know by his killer ninja looks.

Underneath the cyclist’s sleek helmet: a bandanna. Below the rim of the bandanna: steely sunglasses. Wrapping from the bandanna to cover the rest of the face: a hard face mask.

All in all, the cycling outfit looks like something straight out of a ninja movie. But what battles are there for a modern day bicycle ninja to fight? Just as in a Hollywood film, these ninja lookalikes toil to protect the young and the old from a common threat. And as it turns out, that ninja-like mask and outfit isn’t just for show. It protects bicyclists from a very real enemy.

What enemy do bicycle ninjas fight? Air pollution from car exhaust. Air pollution levels in Korea’s cities are serious and sometimes fatal.

There is a strong and increasingly clear connection between car exhaust and life-threatening lung conditions. In South Korea, the number of deaths from lower respiratory conditions nearly doubled from 1992 to 2002. Worldwide, the World Health Organization estimates that 3 million people a year die from diseases related to air pollution. And this isn’t just in far-off countries. It includes Americans, Chinese, French, South Koreans, etc. In South Korea, asthma in particular is becoming more common. Currently, 3.9% of the population as a whole suffers from asthma. This number grows to around 12% for young children and the elderly.

Therefore, South Korea’s ninja cyclists are fighting a worthy battle. Forgoing the car, they ride together, emitting no pollution and encouraging others to do the same.

Where do South Korean Bicycle Ninjas Do Battle?

South Korea, while not a bicyclists haven, does offer some wonderful bike routes and options. Three of the best include:

• Rice Paddies. There’s nothing like cycling through the rice paddies in the morning. Though I wouldn’t say that I’m a full fledged bicycle ninja myself (I lack the proper ninja attire), I regularly enjoy bicycling through the rice paddies to the north of my house. Smoothly paved bike lanes with well-marked bicycle signs designate these and other rice paddies in South Korea as a great bike route.
• The Cheonggyecheon greenway. A newly restored 6 km greenway runs alongside the Cheonggyecheon stream in the heart of Seoul’s urban jungle. It’s a marvelous place for a stroll as well as a bike ride. Just relax and peddle slowly; the Cheonggyecheon stream is also a favorite walkway for pedestrians, and as Mark Seall’s article earlier this week showed, it’s important not to traumatize pedestrians with your ninja biking skills.
• Secondary and tertiary roadways. South Korea is full of farming roads, small side-roads, and other paved surfaces with few cars. Bicycling along these roads, I’ve found, is by far the best way to discover hidden temples and forgotten neighborhoods.

There are many other wonderful areas to explore by bike. Meanwhile, you’ll know that you’re taking a humble but important stance against air pollution.

Bike on, bicycle ninjas. Bike on.

May 6 was World Asthma Day. Since car exhaust can lead to asthma as well as global warming, we thought it would be a good day to highlight the importance of not idling your car or truck engine.

What makes idling especially bad for health is that drivers tend to idle in gathering places - by sidewalks, schools, playgrounds, homes, and offices. Breathing in pollution close to the source is more dangerous than farther away.

Take a look at the evidence.

Tailpipe Exhaust May Cause Asthma

Tailpipe exhaust from both gasoline- and diesel-burning vehicles contains the pollutants that produce ozone when combined with sunlight and heat. Ozone occurs mostly during the summer months. A warming planet means more hot days, and thus more ozone.

Breathing in ozone irritates and inflames your lungs, and repeated exposure can reduce lung function. There’s a lot of evidence that ozone makes asthma worse. But the Children’s Health Study in California found evidence that ozone causes asthma. The study also found that children can suffer irreversible lung damage as adults from breathing smog.

On top of that, diesel exhaust contains particulate matter (soot). This has long been known to cause a variety of health problems, including aggravated asthma (see CARB report on health effects [PDF]). But as with ozone, there is evidence that diesel exhaust particles may cause asthma, and not just worsen it.

California kids aren’t the only ones to suffer from tailpipe-induced asthma. A 2005 NYU Medical Center study showed that asthma symptoms among children in the South Bronx doubled on high traffic days.

Conversely, reducing ozone can improve asthma rates. During the 1996 Summer Olympics in Atlanta, the city closed downtown to private cars for 17 days. During this time, daily peak ozone levels dropped more than a quarter and hospitalizations for asthma fell by almost one-fifth.

Fight Global Warming, Save Money

There’s no reason to idle your vehicle engine. As I explained my previous post:

• Today’s engines don’t need a warm-up period.
• If you’re stopped for more than 10 seconds, it uses more gasoline to idle than to restart.

Many cities, including New York, have laws against idling, but they’re rarely enforced. We need better enforcement, but we can make a difference with our own actions and behavior.

So in honor of World Asthma Day, switch off that idling engine. You’ll curb global warming pollution, save money on gasoline, and help everyone to breathe better.

Despite all the talk about solar energy, it only generates a measly .1% of electricity in the US. Meanwhile, national demand for electricity is growing by 2% annually. Considering that solar technology has been in use for decades, why is it not more widespread?

Cheap Fossil Fuels

Even though sunlight is free, fossil fuels in the US have been widely available at a very low cost. There are extensive coal fields all across the country. Nationally, coal produces about 50% of our electricity, with a majority of it being used for base load. That means that coal plants produce a steady stream of electricity a majority of the time.

Natural gas however has skyrocketed in price over the last 6 years. It is widely used to generate electricity during peak times, typically on warmer days when we are cranking up the air conditioning. Natural gas plants can start up quickly and come to the rescue when needed, but the cost of fuel has gotten quite high recently.

Solar energy is very capable of producing peak electricity and is ideally suited for for it. Solar radiation is what causes us to need air conditioning in the first place. The utility companies have started taking notice of solar energy’s potential to generate electricity during peak demand.

Real Cost Pricing

When we turn on a light, we don’t pay the real cost of generating that electricity. The federal government absorbs some of that cost through subsidies and the environmental cost is rarely taken into account. For example, asthma is linked to the burning of coal, but I don’t pay for asthma attacks when I pay my electric bill. A carbon tax is one method for accounting for some of these hidden costs.

Scale and Price of Solar

Remember how much cell phones cost when they first hit the market? When larger manufacturing plants are constructed, the cost per unit typically decreases compared to smaller plants. Germany, Japan, and California have all stimulated the solar market. Photovoltaic solar panels have already come down in price by 90% over the last 20 years.

Stable Solar Energy Policy

The US had impressive solar energy incentives under the Carter administration, which quickly vanished when Reagan took office. There is currently a 30% commercial tax credit for solar energy, but it is set to expire at the end of the year.

There are purchase agreements for 3.2 gigawatts of concentrated solar power during 2007, but solar power plants cannot be constructed before the tax credit expires. The coal, nuclear, and oil industries have stable energy policies and the same is needed for solar energy to thrive.
