Join students, faculty, and staff in our campus and millions of people around the world and take part in Earth Hour, the annual symbolic lights out event from 8:30 to 9:30 p.m. local time. 

You can celebrate Earth Hour at home, invite your friends over for a "black-out party" or join events in our area and share your pictures and experiences with us via our Facebook Page: https://www.facebook.com/pg/WCMSustainability
