7 trillion tiny pieces of plastic wash into San Francisco Bay every year, new study shows

The trash rules are a good start, but allow cities to estimate how much they have reduced their trash, and need more oversight and enforcement, said Sejal Choksi-Chugh, executive director of San Francisco Baykeeper, a conservation group.
