Tomorrow, April 22, marks our annual celebration of the planet we live on. But did you know that Earth Day was originally conceived by an American senator as a teach-in – a practical, participatory, action-oriented day of learning about the environment? In 1990, Earth Day went global and is celebrated in more than 175 countries each year; in 2009, the United Nations officially recognized International Mother Earth Day on this date.

Since Earth Day also coincides with a holiday for most Canadians this year, why not plan to spend some time with nature tomorrow? You can find an event near you, or just get outdoors and enjoy some fresh air. Try to learn or notice one new thing about the world around you, and then share that knowledge with others.

Happy Earth Day!
