The Summer Olympics in Beijing are just about three weeks away, and to attempt to lower pollution levels as much as possible before the games start, China is removing half the cars on the road.   The Associated Press reports:

Under the two-month plan, half of the capital’s 3.3 million cars will be removed from city streets on alternate days, depending on whether the license plate ends in an odd or even number.

The plan came into effect yesterday, apparently creating slightly clearer skies and lighter traffic.   In addition to the traffic limitations, China is adding 3,000 buses to the roads by the time the Games start, which will increase the daily bus capacity from 12.5 million to 15 million people.   Beijing has also opened new subway lines, which are anticipated to carry 1.1 million people every day during the Olympics.

The moves to dramatically lower pollution come as some premier athletes have stated they will not participate in the games due to the poor air quality.  As well, the AP notes,

Already, many competitors are choosing to train away from Beijing, and International Olympic Committee President Jacques Rogge has said outdoor endurance events lasting more than an hour will be postponed if air quality if poor.

Experts are unsure what effect the measures will ultimately have, but we can remain optimistic that conditions get better and do not impede any of the games.   Especially the trampoline event.   Best event ever.
