Forget the big stuff. Only legislation, Washington, and Lobbyists will change the big ticks. As for day to day stuff, my thoughts are as follows:
1) If you commute, try to do part if not all via bike. This is true if you are in Carbondale, Vail, San Francisco, or Denver. Do it 2-3 times a week. Kayaking is NOT an aerobic sport, so you'll trim some of those love handles anyways.
2) Recycle, recycle, recycle.
3) Keep your thermostat on low/off when you aren't home, and wear a sweater when you are.
4) Screw AC. Get a swamp cooler or attic fan.
5) Get rid of the fancy SUV. Do you really need it? Most SUV's go offroad less than 90% of the time, and AWD is better than 4WD with truck tires anyways. My dream was a brand new Toyota Tacoma V6 TRD with shell and roof rack. My next car will probably be a Honda Element or Subaru Outback (insert hippy joke here).
6) Go Biodiesel if you can.
7) Purchase wind-credits from your local electricity provider
Keep the hot water heater only as warm as you need it for dishes and showers. 10 mins of hot water is enough, and if you take longer showers, you're wasting water to begin with.
9) Donate to your local environmental non-profit and skip the movie theater for a night.
10) Install energy efficient lightbulbs in your house.
11) Check for drafts in windows and doors, and fix them. Same goes for extra insulation in your attic.
12) Buy local. Sounds stupid but less transportation costs, and less "carbon footprint" in the food you eat means less energy consumed. Plus it is hippy-friendly anyways.
