China announced today the removal of tons of algae from the waters of the Olympic sailing venue. Some scientists blamed China's industrial waste and pollution for feeding the algae population.
The algae clean-up is the latest in an on-going effort to make Beijing hospitable for its Olympic competitors. With poor air quality looming, many top athletes have expressed health concern over competing in the games. Haile Gebrselassie, the world record holder in the marathon, refused to participate citing concerns over the impact of pollution on his asthma.
As populations and demand for energy continue to rise around the world, it's easy to wonder if athletics competition in the United States could begin to suffer due to high levels of pollution.
According to the United Nations, China and the United States are the top two carbon polluters in the world, combining to account for more than one third of all carbon emissions. The photo that accompanies this article was taken from images produced in 2008.
At the time of this writing, more than 30 cities in the United States have declared an Air Action Day. Air Action Days are called when the air quality index reaches an unhealthy level. You can see how your city compares by going to the government's air quality Web site, www.airnow.gov.
Last week, the G-8 Summit leaders pledged to share a "vision" for a low-carbon economy, saying they will work to cut carbon emissions in half by 2050. The move has been sharply criticized by environmental groups, however, because they say the pledge lacks teeth.
With no firm international commitments by the leaders of the eight most powerful countries in the world, can we really expect our air quality to remain hospitable for athletics competition?
