A conservationist goes about life reducing pollution and habitat destruction quietly and without fanfare. One year at work I had a new boss who asked me if I was a tree hugger.
When we met he asked which filing cabinet our records were in. I pointed to a stack of DVD-R's. When the company asked us how they could save $ and still send out holiday greetings I responded "e-cards". When he'd enter my project office the overhead lights were off but my area was lit with a small table lamp with a curly fry bulb. When out doors watching work from my truck the truck would be off unless I was moving from place to place. Stuff like that. Yet to me all that was just normal. Waste not, want not, right?
The trash truck goes by my house once a week but only stops at my house about once a month. My environmentalist do gooder neighbors can's are over flowing weekly.
When the guy asked me if I was a tree hugger I pointed north and said "about 5 miles that way a gigantic coal powered generator sends polluted air towards my athsmatic son and I'm just doing what I can to reduce the number of loader buckets of coal get dumped into the furnace each day".
Now, I know envirionmentalists who place their pajamas in the clothes dryer to warm them before bed. They look down on me for using plastic straws while they waste more plastic in one day than I do in a week. When my house is chilled I add clothing. They turn up the furnace. When I vacation it's to fix a shed or visit a park on my bicycle. They fly in airplanes coast to coast or ride on gigantic cruise ships to tropical islands then tell me my full sized pickup is ruining the planet.
It's one thing to be a good steward, but just do it and shut the front door about it.
