Dozens of environmental groups from California and Arizona rallied in front of the Environmental Protection Agency’s San Francisco office a day before the city's Earth Day celebration and March for Science.
The groups' leaders met with Alexis Strauss, the EPA’s regional administrator for the Pacific Southwest, to express their concerns about climate change and its impact on low-income communities and communities of color.
They're also demanding that EPA Administrator Scott Pruitt step down.
Bradley Angel, the executive director of Greenaction, a health and environmental justice group, helped organize the march.
“The purpose is for the people most affected to say, ‘We're already dumped on and sick, and our people are dying. We need more protections, not less.’ This is resistance against Trump and his policies,” he said.
