For those who wonder how effective Earth Day really is and how to participate, the 'A Brief History of Earth Day' infographic provides a great starting point.
This infographic informs readers of how Earth Day became a globally recognized day of eco-awareness. For example, it shows that in 1969, Gaylord Nelson was impacted by the enormous oil spill in Santa Barbara, California, and on April 22, 1970 he began to raise awareness. This translated to 200 million people in 141 countries by 1990, and thus Earth Day had become a viral concept. Political figures became involved, bringing nations together under a flag of friendliness towards Mother Nature. The infographic moves on to explain how people can save money with small changes to their daily lives, and help the environment at the same time.
