On June 5, 1972, the unitednations established World Environment Day to inspire awareness and action for the protection of our planet. This day reminds us that we all share the responsibility of caring for Earth. Of the more than 5,000 planets discovered beyond our Solar System, Earth is the only one where we know life exists. It is here that everyone you love, everyone you know, everyone you’ve ever heard of, every human being who has ever lived, lived out their lives. Earth is the cradle of life. Let’s protect the only home we know.
