We are all about saving trees, but if you’d like to spread the good-n-green word by posting an Ideal Bite tip in a public place, we encourage you do so on recycled paper. Thanks and Happy Biting!

If 10,000 LA Biters take one 3-mi walk roundtrip (to a friend's house, the market, the bar, etc.) instead of driving, we'll avert the weight of nearly 10 Priuses in CO2 from entering the environment.

The 150 entertainers for the Live Earth concert, such as Madonna, the Police, and Kanye West, were encouraged to skip the private jet and fly commercial to their gig - 99% of them complied.

Rock-’n’-Roll Wall of Fame

The Bite:

If you see exec producer and founder of Live Earth concerts Kevin Wall walking the streets of his 90210 hood, give him a high-five (or hold up your lighter). After seeing An Inconvenient Truth, Kevin got Al Gore on the horn and created last summer's 24-hour, seven-continent concert series, which conveyed Al's SOS (Save Our Selves) global warming message to more than 2 bil people. This fall, Kevin's planning events at major universities to encourage students to vote on environmental issues. And the Wall fam walks the talk, literally: On weekends, they leave the hybrids at their partially solar-powered home and get around on foot. Rock on, Kevin.

Wanna Try?

We hear Kevin and his brood mountain-bike and hike at neighborhood park Franklin Canyon Park, 2600 Franklin Canyon Dr., Beverly Hills.
