BERLIN, GERMANY - MARCH 29: A cyclist drives past a parked car and its exhaust pipe on March 29, 2005 in Berlin, Germany. Many German cities are close to violating EU-regulated emission limits of so-called fine particle dust, which mostly comes from diesel engines and worn tires. The German city of Munich recently exceeded its limit, and other cities, including Berlin and Frankfurt, are likely to do so soon. While other countries in Europe, such as Italy and France, have been dealing with the growing problem, Germany has lagged behind. An estimated tens of thousand of Germans die every year because of the medical consequences of breathing in fine particle dust. Several German automakers recently announced they will introduce particle filters for their diesel cars sooner than originally planned. (Photo by Sean Gallup/Getty Images)
