It's not every day that you see hundreds of scientists in white lab coats taking to the streets, but that's what happened Tuesday in the Canadian capital of Ottawa. The scientists and their supporters marched outside Parliament chanting, "No science. No evidence. No truth. No democracy."
It was a mock funeral at which protesters said they were mourning the "death of evidence." They charged Prime Minister Stephen Harper with muzzling government scientists and slashing environmental research.
One of the triggers of Tuesday's protest was a high-profile fight over an unlikely place—a little-known research facility deep in the Canadian forest. Reporter Ari Daniel has the story.
