One major problem that continuously plagues Beijing is the battle to clean up the city’s pollution. There rating is worst than Los Angeles. Despite our spending only three days in Beijing we couldn’t help but feel overwhelmed by the densely polluted air. I felt like, I could literally reach out and grab puffs pollution in my hands. Don’t be surprised to see people walking or riding bikes with designer style surgical mask. It’s not to protect people against “SARS,” but to help them breathe. In order to ebb the tide of pollution, Beijing has launched a program to bring back bike riding to curtail car traffic.
