No points for guessing: young people who've absorbed "Green" messages via TV think it's cool to describe themselves as Green, but they're not as serious about it as older Granola Greens.
Attention, young readers! Liz Klimas and I have just challenged you! Defend your honor! Here are some things you can do: Walk instead of driving. Eliminate something electronic or online from your life (use the non-electronic alternative). Carry your lunch in a metal box instead of buying take-out in a styrofoam box. Play an outdoor game instead of an electronic game. Read a book instead of watching TV. I dare you!
