The March for Science (formerly known as the Scientists' March on Washington)[6] was 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.[7][8][9][10][11] According to organizers, the march was a non-partisan movement to celebrate science and the role it plays in everyday lives.[12] 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.[11][13] The March for Science organizers, estimated global attendance at 1.07 million, with 100,000 participants estimated for the main March in Washington, D.C., 70,000 in Boston, 60,000 in Chicago, 50,000 in Los Angeles, 50,000 in San Francisco,[14] 20,000 in Seattle, 14,000 in Phoenix, and 11,000 in Berlin.[15]
A second March for Science was held April 14, 2018.[16] 230 satellite events around the world participated in the 2nd annual event, including New York City,[17] Abuja, Nigeria,[18] and Baraut, India.[19] A third March for Science took place on May 22, 2019, this time with 150 locations around the world participating.[20]
The March for Science organizers and supporters said that support for science should be nonpartisan.[21][22][23] The march was organized by scientists[1] skeptical of the agenda of the Trump administration,[22] and critical of Trump administration policies widely viewed as hostile to science.[24] The march's website stated that an "American government that ignores science to pursue ideological agendas endangers the world."[21][22]
Robert N. Proctor, a historian of science at Stanford University, stated that the March for Science was "pretty unprecedented in terms of the scale and breadth of the scientific community that's involved" and was rooted in "a broader perception of a massive attack on sacred notions of truth that are sacred to the scientific community."[26]
