I met 2-year-old Eliyah Keller at the Sarasota Naturally street fair. He was sporting a t-shirt that said, 'Be green. It's cool!' Start 'em young. Growing up in the '70's during the energy crisis and inflation, I was taught when you left a room you turned off the lights...and fans...and radios...and TVs. You never left the refrigerator door open. And, living in Michigan, we always turned the heat down when we left the house. It was all about saving money. Amazing how behavior like that sticks with you. Years later, I still follow those rules.
