World Population Day: records high

404 participants pose for a photo during the "Next Einstein" competition which set a Guinness World Record for the "largest gathering of people dressed as Albert Einstein" in Toronto, Canada, March 28, 2017. World Population Day falls on July 11th every year. It was first observed on 11 July 1987, when the world population reached 5 billion.
