San Francisco is poised to close up to 40 of its busy 68 bus routes due to the financial strain caused by the coronavirus pandemic. This is according to an agreement arrived at during the San Francisco Municipal Transport Agency (SFMTA) meeting last week. According to the organization, the fares in the city have dropped by 90%, making it infeasible for most buses to continue operating. This announcement means that commuters will have to revert to using personal cars, a situation that could spur air pollution to new levels.
