Apr 16, 2015 — By WSU News Services — Celebrate Earth Day from 11 a.m.-1 p.m. Wednesday, April 22, on the RSC's north patio. You can do a lot for the Earth. Start with bamboo and bring it to life. Bring home your own bamboo plant, complete with a planter and rocks. Also, don't miss out on the zoo exhibit and groups promoting the essence of Earth Day with activities, information and more. The more you know, the more you can do.
