Sort of a continuation of the economic doom thread in the G-Spot.
Like most of you (I hope), we recycle glass, plastics, metals, and paper.
We also have a worm farm and some chickens to deal with kitchen and garden waste. When possible we choose products with the least packaging. We have replaced our old wood-burning stove with a pellet-burner. We shower no more than three times per week, and those showers we have at work. We bike or walk to work, grocery, doctors, post-office etc...and only use our 660cc car when the distance or weather is not practicable for biking or walking. We only heat our central living area, and use hot water bottles at bedtime for warmth in those other areas. Naturally we have those highly polluting energy-saver bulbs. A 40 watt 'daylight' bulb is an awesome thing to behold in the middle of winter ;). We sell or give away stuff that we are pretty sure we will no longer use. We plan many of our meals around "what's left in the fridge". We buy locally grown, in season and organic where ever practicable. We turn stuff off if we're not intending to use it for at least the next our. We have an attic ventilation system which captures heat lost or gained through the ceiling to both warm and dry the house. We say a big "NO" to junk mail in our letterbox. We prepare our own meals from fresh produce 6 days of the week, but buy fast foods for ~one day each week. We make or modify much of our own clothing and gear, and buy virtually ALL of our casual clothes from second hand shops (fun shopping!!). We dehydrate most of our backpacking meals, though not sure how the electricity cost of dehydrating compares to buying freeze-dried. All of our electricity is from hydroelectric sources (this is something many people in the world don't have a choice over, and it comes with it's own environmental costs) and our pellet burner fuel comes from the sawdust left from the forestry industry.
Most of all, we are always looking for ways to improve our existence on this little fragile planet. This includes joing clubs where we meet up with and go hiking with like-minded people. This allows us to not only car-pool to our destination, but meet a diverse range of folks that you might not have otherwise got to known...
