My lifestyle for sure is "greener" now that I no longer contribute to the waste of gas from field circus. Also, I no longer pick up rags, which saves on the trees that no longer get cut down, the pollution no longer placed in the air and water from the rags not produced because I no longer pick them up, and the gas not used in delivering them. And I no longer contribute to the non-recycling practiced at the Kingdumb Hell. Anyone else notice that those dumps never have recycling bins?
And, by being more "materialistic", I buy better quality. Now I have better things that are going to last much longer, preventing them from ending up in landfills or wasting energy making new crap. I got LED light bulbs throughout, meaning fewer or no blown bulbs to pollute your drinking water with mercury or waste energy making them and shipping the squiggly things from China. (And less wasted energy running them--when I made the switch, I calculated that I was wasting some 55 watts per bulb-hour, out of which only something between 10 and 15 was accounted for by bulb inefficiency. What was the other 40-45 watts doing to the environment?).
I also have better appliances. A new toaster that is professional quality (no worrying about a fire). A high-grade water filter that takes fluoride out (and doesn't leak or require monthly cartridge changes, keeping filters and cartridges out of the landfill). Nicer utensils that will not be ruined so easily. And, flashlights, lanterns, and batteries that will not end up polluting the landfills the first time the lights go out and they fail. Using NiMH batteries prevents batteries from entering the landfill, and those Eneloop batteries can be used like alkalines in my devices (again, preventing batteries from entering the landfill, pollution from making and delivering the batteries, and devices from being damaged by leaky alkaline batteries from entering landfills).
I am now finding out that being "materialistic" sometimes ends up saving you money (and time, and trouble) down the road. Less wasted time replacing things that don't wear out. Less mercury in your drinking water from the squiggly thing I don't buy because I got LED's, not to mention not wasting money and time replacing them. Fewer dead batteries reaching the landfill because I use rechargeables. Fewer clothes being tossed because the ones I buy are more durable. And, when the dollar becomes toilet paper, I will find myself with things that still have 10 or more years of life--instead of having them wear out or break within a few months.
