JAKARTA, INDONESIA - NOVEMBER 11: Bike To Work group members conduct a tree planting program on November 11, 2007 in Jakarta, Indonesia. There are currently around 3,000 members of Bike To Work (B2W) in Jakarta, most of whom ride their bikes to work every day. Its membership unfortunately pales in comparison to the 3 million motorcycles and over 2.5 million private cars that travel on the city streets every day. Jakartans breathed "clean air" for only 45 days last year, according to the Cities Environment Management Agency. (Photo by Dimas Ardian/Getty Images)
