All of the little things we do for the environment, good or bad, add up and make a difference. With that said, recycle, turn off lights you aren't using, walk when you don't have to drive, take shorter showers, etc,
For now, I am just going to focus on the showers since it is a peeve of mine. My wonderful wife tends to take 20 minute showers and it drives me a tad crazy. All of that water going down the drain, wasted. I have tried nagging, the shower length does not change. I think I may have a solution,
I think I am going to get a shower timer like the digital duck timer that suction cups to the shower wall and counts down a time set by the user. I will start off with 10 minutes and subtract one minute every two months until I can get her down to a reasonable 5 minute shower.
Or you can opt for the less techy approach (which I think is pretty cool) that uses the old sand timer on a suction cup for the shower wall.
