These celebs stood up for the planet at the March for Science

If you didn’t know already, people of the planet are piiissed. And that includes celebrities, who attended the March for Science yesterday in cities around the country. From January’s Women’s March to last week’s Tax Day March, citizens of the world — including the brightest stars — are standing up and speaking out on the issues they care about en masse.

And yesterday’s March For Science was no different. Part Earth Day celebration, part protest of the Trump administration’s proposed rollbacks of environmental protections, tens of thousands of climate-conscious demonstrators flooded the streets of over 600 cities worldwide in support of the study of science and scientific inquiry, particularly as it pertains to climate change.
