Today is the 40th anniversary of Earth Day. Come out and celebrate with the KU Environmental Action Club. There will be environmentally friendly vendors, biodiesel vehicles, live animals, live music, entertainment and more. You can also get free t-shirts with a donation to a local non-profit agency. This is taking place behind Schaeffer, on the library’s front lawn, from 8:00 a.m.-6:00 p.m. Don’t miss this event!
