Party for the Planet

Earth Day is here again to remind citizens to protect our planet’s resources. The annual celebration at Como Park Zoo and Conservatory invites guests to participate in environmentally themed activities and exhibits. Think you could live small? Explore a 110-square-foot tiny house and learn how easy it is to make energy efficiency improvements to large and small homes. Listen to zookeeper talks and view programs on gorillas and polar bears. This weekend also marks the final days of the Spring Flower Show. (10 a.m.-4 p.m. Sat.-Sun. Free. Como Park Zoo, 1225 Estabrook Dr., St. Paul. 651-487-8200. comozoo conservatory.org.)
