Earth Day, observed each year on April 22, serves as a celebration of the birth of the modern environmental movement.Started in 1970, Earth Day was sparked by the country's burgeoning understanding of how contemporary industrial practices were negatively impacting the environment.The celebration was designed to bring awareness to many of the dangers affecting the environment — air pollution, water contamination, habitat destruction, and so on — and to encourage people to take action in protecting their surroundings.
