April 29th, 2017, the 100th day of Donald Trump’s presidency, more than 300,000 people marched in support of science. “Climate, Jobs and Justice” was what over quarter million people stood up for on that day. 200,000 people marched in Washington DC alone. People in as many as 370 different Sister Cities came out in force, supporting scientific research and principles in the face of the Trump Administration’s magnification of the strange and illogical denial of science by members of the Republican Party.
