School has started again, which means its group visit season at the Wells Reserve at Laudholm. Those schools fortunate enough to have bus rental money are sending classes our way, and our team of educators are taking the kids out on the trails, down to the beach, and through the science and history of this 360-year-old place.

For a long time, I didnt understand what environmental education was. Im a perennial skeptic, particularly when it comes to claims from my own liberal brethren, so, over the past ten years of my environmental career, Ive always taken my colleagues proscriptions with more than a grain of salt. What finally convinced me to start applying their lessons was, of course, that grand old motivator of cynic and sucker alike: money.

Highway diesel fuel costs about 8% more per gallon than unleaded, but my Volkswagen diesel goes 20% further on a gallon than the unleaded model. Then, after some careful data collection on my daily turnpike commutes, I discovered that if I set the cruise control to 74 miles per hour (down from 80), I could get nearly 50 miles per gallon. Another 20% increase in MPG, for just a 7.5% decrease in speed? I wonder what I could get at the speed limit, and if I would still pass every Prius I see.

Even though Maine is awash in fresh water, I still feel the urge to conserve. So I live by the old camp maxim: if its brown, flush it down; if its yellow, let it mellow. My wife is not nearly as keen about our House Toilet Rule as I am. I need to show her the water bill. (Or not. It likely costs 2 cents a flush& Im being ridiculous.)

My six-year-old wants to be a veterinarian when he grows up (what six-year-old doesnt?), and over dinner recently he put two and two together  eating meat means animals die, Dad. So now hes converting the entire family to vegetarianism. I love steak, and pork, and chicken, and seafood; this has been very difficult. But so far, his accusatory looks have cut our carnivorous episodes by more than half, and our food budget similarly. (Lobsters, despite PETAs best efforts, are still a part of our summer dinners, though.)

Recycling. Oh, recycling. Ive had such doubts about recycling. Where does all that stuff really go? Can milk cartons (with the last drops of milk in them) really commingle with beer bottles, cardboard pasta boxes with plastic windows, and paper credit card statements? We continue to throw everything we can into our blue bin and trust that somewhere, someone is getting paid to sort it all out. I have made one change in the past year: all the refundables now go into a CLYNK bag tagged for our elementary schools PTA. Drinking during Pats games now contributes to my boys educations. Pass the kale chips.

I readily admit that Im no green guru. Ive clung to a certain consumerist way of life, despite arguments and evidence and guilt. But I have changed, gradually. Moneys been the best incentive; in difficult economic times, weve all scaled back where we can. Its been comforting, and also thrifty, to realize that the lessons of environmental education do work. Ten years of colleagues have been right: going green, every way you can, makes dollars and sense.
