"The March for Science (formerly known as the Scientists' March on Washington) is an international series of rallies and marches held on Earth Day. The inaugural march was held on April 22, 2017 in Washington, D.C., and more than 600 other cities across the world. According to organizers, the march is a non-partisan movement to celebrate science and the role it plays in everyday lives. The goals of the marches and rallies were to emphasize that science upholds the common good and to call for evidence-based policy in the public's best interest.
Particular issues of science policy raised by the marchers include support for evidence-based policymaking, as well as support for government funding for scientific research, government transparency, and government acceptance of the scientific consensus on climate change and evolution. The march is part of growing political activity by American scientists in the wake of the November 2016 elections and the 2017 Women's March."
