Pollution is so bad in the Brazilian city of Sao Paulo that authorities plan to stop 2 million cars from entering the downtown area today. Under an anti-pollution plan announced last week, 500 police and employees of the government's environmental protection agency are scheduled to block off the city's 200-square-block central district before the morning rush hour, permitting only buses and official vehicles to enter the area until 9 p.m.
