Sorry, no big Earth Day post - too busy with work, the job search and other things.
Just a quick tip that is one of the easiest/painless changes you can make. Don't let the water run while you're brushing your teeth. This saves an average of 3,000 gallons a year. Same goes for shaving, washing dishes, etc.
If you want to go one step further - when running the water to get hot water for dishes or shaving, fill up your Brita pitcher, coffee pot, tea kettle, dog bowl, etc.
Though recycling gets all the press, the theme (in order of effectiveness) is - Reduce, Re-use and Recycle. And with money so tight these days, reducing consumption is top of mind for a lot of people. If the environment benefits as a result of cutting back, so much the better.
