On April 22, scientists and science aficionados will gather for the March for Science, a series of demonstrations planned at more than 100 cities worldwide in support of a number of scientific causes.

About 100 groups have announced their partnership with the march, including the Alliance for Science, American Federation of Teachers, Genetics Society of America, American Association for the Advancement of Science (AAAS) and American Psychological Association.

The march has drawn support from a wide range of groups and causes, including those concerned that President Donald Trump’s administration has appointed people who are opposed to climate science, basic research and environmental programs. It also comes amid a campaign to urge scientists to run for office, in part to protect those programs and promote scientific approaches to public policy. The march’s mission statement states that it “defends science and scientific integrity, but it is a small step in the process toward encouraging the application of science in policy.”
