WASHINGTON — Thousands of scientists and their supporters, feeling increasingly threatened by the policies of President Trump, gathered in Washington on Saturday under rainy skies for what they called the March for Science, abandoning a tradition of keeping the sciences out of politics and calling on the public to stand up for scientific enterprise.
Mona Hanna-Attisha, a pediatrician who helped expose lead poisoning in Flint, Mich., and who addressed a rally before the march, called the protest the beginning of a movement to ensure that governments do not dismiss or deny science.
“If we want to prevent future Flints, we need to embrace what we’ve learned and how far we’ve come in terms of science and technology,” Dr. Hanna-Attisha said in an interview.
The demonstration in Washington was echoed by protests in hundreds of other cities across the United States and around the world, including marches in Europe and the Asia-Pacific.
