In what he calls "maybe the most important words I have ever spoken," acclaimed science educator Neil deGrasse Tyson makes the case that the recent rise of science denial in The United States represents an unprecedented threat to the foundation of our democracy.

When his impassioned plea was released in April 2017 as the short film "Science In America" by Redglass Pictures, Tyson struck a nerve worldwide. The video has accumulated over 65 million views on Facebook, was used to open the 2017 March For Science on the mall in Washington, DC, and became a rallying cry for a movement to bringing science back to center of American public policy.
