April 22 is Earth Day and if you live in Los Angeles, you can enjoy it at the Wilshire Center located at 3700 Wilshire (at Oxford). Everyone is encourage to ride their bicycles to the event, they even have a bike valet for cyclists. If you don't have a bike or it's too far to ride, then please take public transportation, or at the very least car pool and lessen your carbon footprint.
Bring your old electronics to recycle, like old TVs, computer monitors, and small electronics. There will be live music, dancers performing traditional dances of Korea, El Salvador, and Bangladesh, food from the local farmer's market, gardening demonstrations, drumming lessons for kids, and you can adopt a tree (or two or three). All this will start at 11am and go until 3pm, so plan a play date while doing something good for the earth.
