You don't need a scientific calculator to know that the March for Science was a massive success.
Stretching across the United States — as well as globally from the North Pole to New Zealand — the March for Science saw tens of thousands of people take to the streets on Earth Day in many cities, adding up to totals much higher nationwide.
Here are a few photos that begin to capture just how huge crowds nationwide became throughout the Earth Day celebration.
