I have other things in mind, as well, but if I mentioned them, I might be de-railing tent's thread and I really don't want to piss him off ( ), so I'll leave it up to him.
I deliberately left this wide open figuring it would wander around depending on the POV of all respondents. Mostly, the fun part is for the individual to examine their own need-want world. It's just a guess, but it might slow down some of our overt (and ridiculous) consumerism. Oh, you can't piss me off. I don't get pissed off - ever. People can keenly disappoint me now and then, and I might say something about that from time to time, but I refuse to waste energy being pissed off at anything or anybody.
What disturbs me about rampant consumerism isn't the waste of valuable materials, it is the waste of needed assets (cash) and time. Most of us generate an income that allows our needs to be met - if we don't get stupid with kidding ourselves that a lot of what we say we need, is really just a want.
Just for the record, there is very little material that is "non-renewable". We may not have the technology at present to convert all materials into useful forms, but almost everything is renewable. In fact, all of our 'garbage' residing in landfills is a savings account for the future. At some point, those landfills will be mined and what is garbage today will be a rich resource tomorrow. It just waits for the technologies to catch up with us.
But there is no reason to take easily used materials and turn them into less-usable forms just to fulfill wants. We will never stop consumerism, but we can slow it down and make it a little easier for future generations. So how do we slow things down? It's up to each of us. I'm not into sanctimonious superiority self-denial crap. If I NEED something, I'll figure out some way to have it, and what I need will be different than what anyone else needs. The idea is to be thoughtful and honest with ourselves about defining need -vs- want. I could be wrong, but I suspect that most of us could live with a hell of a lot less than we routinely acquire.
I find it interesting that we have people who routinely complain about being a "slave" to the system, and yet they have enough excess capital to own a computer, pay for internet service, and have the luxury of time to sit and bang away on a keyboard - complaining about being a slave. ?????? There is a disconnect there of some kind...
OK. That's enough for the moment. Hopefully, we'll get a few more different viewpoints going...
