Seattle will join the global March for Science on Saturday, April 22, starting at Cal Anderson Park and ending at the International Fountain at the Seattle Center.

“We want to inspire optimism in science again and say that this powerful tool is yours to help illuminate and improve the world,” says march co-founder Miles Greb in a news release. “That will take both the efforts of protecting the hard-earned knowledge science has given us and fostering a new generation of scientists and science enthusiasts.”

A celebration of science, with featured speakers and events, starts 10 a.m. in Cal Anderson Park, followed by a march to Seattle Center at noon.

Speakers will includes Washington First District Rep. Suzan DelBene, Seattle Mayor Ed Murray and Michael Fox, former climate change advisor to the Environmental Protection Agency’s Region 10, who resigned March 31 “to protest anti-science developments at the agency,” according to the news release.
