Earth Day began in 1970, when Sen. Gaylord Nelson brought environmental concerns to attention after years of ignoring how we affect the planet. Earth Day has been celebrated on April 22 for the past 41 years. In 1990, the U.S. holiday went national, and is now celebrated by 175 countries. In 2009, the United Nations recognized the date as International Mother Earth Day.
The holiday has expanded to what we know as Earth Week, mainly due to efforts by universities to provide more activities and awareness functions that could not be completed in a single day. One of the main goals of Earth Week is to educate others on how to be eco-friendly.
There are no requirements for celebrating Earth Day or Earth Week, except for a commitment to do right by the earth. Make some changes to your daily habits, like starting a compost bin or repurposing items instead of throwing them away. If each of us make one or two small changes, the whole planet will feel the impact.
