Earth Day
Earth Day has been marked on April 22 every year since its
inception in 1970. This year, organizers are calling for three
days of climate action, from
April 20 to 22, but expect the entire week running up to Earth Day—sometimes
called Earth Week—to be a time when environmental issues take centre stage. Earth
Day became an international campaign in 1990, when environmental activists
asked one of the original organizers, Denis
Hayes, to help create another event to spotlight the
ecological challenges facing our planet.
