Marching for Women’s and Human Rights

Hundreds of Chapter members and supporters joined with tens of thousands to march for women’s rights, our safety, our health, our families and our communities.  The march was held the day after the inauguration of Donald Trump and signaled to the Trump administration that we are gravely concerned about the impacts of climate change and the implications of an Administration that promotes climate skepticism, advancement of fossil fuels, an extractive economy, racism, bigotry and sexist oppression.
