Khalana McDonald, BeJanai Reed, Ana Sicay, and Klara Shawky help clean up the Los Angeles River during a Green Living Youth Program event sponsored by Ivy Terrace, the LEED Platinum affordable housing complex in Los Angeles where they live. This resident engagement program offers weekly get-togethers focused on sustainable living, including energy conservation and recycling, and participating households receive free green cleaning products and workshops for adults.
