Saving the environment is a tall order, but small steps taken by individuals can make a big impact. Writer and gardener Russ Klettke will present "Best Practices for Your Backyard" at 6:30 p.m. Tuesday at the 47th Ward office, 4243 N. Lincoln Ave.

Klettke will tackle topics including urban flooding, rain gardens and the "whys and hows" of native plants and trees, providing concrete steps for greening yards, porches, apartments and condos.
