Earth Day was established in the 1970s as a way to raise awareness about the impact humans have on the planet. It continues to be a globally recognized holiday that encourages communities to enjoy nature while engaging in efforts to protect it. Officially, Earth Day is April 22, but events celebrating Mother Earth are planned all week long in Orange County. Guided nature hikes, beach cleanup events and oceanfront yoga are just some of the eco-friendly activities offered.
