Girls with painted faces and placards with a message on environment on World Earth Day (April 22). Earth Day is celebrated in over 190 countries worldwide with this year’s theme of encouraging people to plant more trees to save Mother Earth. In 1970, the year of our first Earth Day, the movement gave voice to an emerging consciousness, channeling human energy towards environmental issues. Forty-six years later, we continue to lead with groundbreaking ideas and by the power of our example. The movement continues to inspire, challenge ideas, ignite passion and motivate people to action.
