The city of Los Angeles has 10 million people, 8 million cars, and a heck of a lot of pollution — pollution that disproportionately affects low-income communities of color. Francisca Porchas, an organizer with the Clean Air, Clean Lungs, Clean Buses Campaign, is working to change that. As InterActivist this week, Porchas chats about the city’s car culture, her trip to New Orleans in the wake of Katrina, why she hearts the people of Tuvalu, and more. Send her a question of your own by noon PST on Wednesday; we’ll publish her answers to selected questions on Friday.
