The law of supply and demand does not manifest itself at light speed. I don't think it's a given that an economic feedback loop would operate in time to prevent an ecological disaster. Especially when numerous interventions, political or otherwise, are utilized as stop gap measures that forestall the immediate negative consequences to the consumer but only worsen the ecological consequences for humanity. Population blooms and crashes happen all the time, I don't know that humans are necessarily immune to it. From a systems perspective it is entirely possible that the negative feedback loop that can prevent resource depletion is entirely overwhelmed by numerous positive feedback loops that 21st century humans are more attuned to.
Roman roads were not equaled until the 19th century. Aqueducts were built to a tolerance that was not achieved again until modern times. Indoor plumbing was lost for over 1000 years. 2000 year old breakwaters made of Roman concrete surpass anything we have today. Current Portland cement lasts about 50 years in salt water. The Greeks had nearly built a steam engine before their civilization collapsed and their knowledge wasn't surpassed until the 17th century.
With a decay in current infrastructure we would lose technological knowledge at a rapid rate. There are scientific advances today that perhaps a few dozen people in the world understand. The level of specialization in modern society is such that most of the technology that people use is not understood. Most people can't fix their own bicycles. If modern day support, money, and infrastructure is removed, we would lose a vast amount of knowledge within only a generation. I dunno, I think the perpetuation of knowledge is much more than figuring out how to power a solid state hard drive.
it's going to happen anyway, but there's no reason to start dying off before the resources are exhausted.
Well, that's a pretty decent point. The only thing I can really offer in response is that learning to do more with less has a number of personal benefits outside of some utopian idea that if everyone does it we'll be able to sustain our existence forever.
It seems that people can put three things toward any problem: time, skill, or money. Most people work so much and with such a specific set of skills that they have neither the time nor the skill to solve anything else.So they throw money at it. Having more time or a wider array of competencies sacrifices efficiency for resiliency, but I would say that in an economy of increasingly scarce resources (which seems like where we're headed) resiliency will probably have a pretty high value. Now whether one, today, can tell themselves that it's more fulfilling (of greater value) to have the time and skill to fix problems on their own rather than throw money at it (or petition the government to throw money at it) is probably pretty variable and likely requires a fair amount of self-reflection.
I will say that spending less money (and I'm conflating this with consuming fewer resources which maybe isn't completely accurate but I think so) does not necessarily entail poverty or a lower standard of living. People have numerous types of capital (social, intellectual) such that the people living below the poverty line (around 11k I think in the US) which I suppose I am one of are not necessarily impoverished. The truly impoverished are probably like that for a greater variety of reasons than the fact that they have less than 11k to spend on things.
And I think you're right. The world as a whole will not voluntarily go back to pre-Industrial times. But the individual can do things today such that when it's forced on them (should it happen in their lifetime) they are potentially less affected or less vulnerable.
It's interesting to see the amount of vitriol heaped upon Taco Cowboy. I don't think he was telling you that you should be forced to change your lifestyle. He was questioning it. Which is pretty much all slashdot does-question things. And keep in mind, I'm not responding only to you but to the whole host of responses above yours as well.
I think many humans assume that they (as a species) are exceptional and exempt from the laws of nature. This belief has been strengthened by our stunning growth, progress, and dominance since the Renaissance and through the Industrial Age. But there are two catalysts for this growth that are important to consider:
The size of the world literally doubled when Columbus discovered the New World. This doubling provided a vital but transitory safety valve for an overpopulated Europe. The planet will likely not double again.
Fossil fuels began to be used and are now burned at a rate greater than 10,000x their rate of formation. This gave the world a temporarily greater carrying capacity that has subsequently been utilized. It allowed for advances in transportation, resource extraction, globalization, and agricultural production that cannot be sustained without an easily transportable, energy dense fuel source.
But in our dominance, we have also changed the environment that allowed such things; we have taken the opportunity of cheap, abundant energy to not only massively increase our population but to increase the amount of energy per capita required to exist. We clothe ourselves, we build houses and insulate them, we install central heating and air conditioning and connect these sort of human-technological adaptations by a vast network of roadways and railroads and airports. Genetic adaptation in some sense becomes unnecessary given the rate at which cultural adaptation can occur to solve the same problems. But what allowed us to so quickly overcome our environment, technology and cultural transmission of adaptation, also allowed us to quickly and massively overshoot any naturally occurring mechanisms of negative feedback and stabilization. The traditional roles and occupations continually become oversaturated and diversification occurs. But because this increased capacity for diversification is dependent on the draw down of nonrenewable sources, they are niches in what can really only be described as “detritus ecosystem.” And the cycle of a detritus ecosystem is a magnificent bloom and crash based on the plentiful but quickly exhausted and finite availability of nutrients. We are functioning in the manner of algae blooms and yeast cells in a vat of wine.
Honestly, man will probably stop changing its environment only when it ceases to exist, no matter what we do. I'm really not making a moral judgment. It's just the circumstances we are in. But to say this guy is a Nazi because he suggests today's current cars are wasteful or to reduce his argument to one arguing for the forced reduction of the human population seems a bit hysterical.
Yeah, I do think we have too many people for the world to sustain. Especially if they all want to live like Americans. The answer is probably not to sterilize them, but maybe Americans can reduce their standard of living.
I'm 18 and a sophomore at the US Naval Academy. I suppose I do serve in the military, though it seems to be in a somewhat limited capacity. The military with training wheels maybe.
I suspect moral courage is easier and more visceral the closer you are to the consequences, and reservations probably become easier to set aside the higher up you go. Matters lose that moral dimension as decisions become more a matter of policy and you become rather far removed from its consequences. I'm not really sure that this is a horrible thing. The military carries out policy, and I don't think that any one man really ever has more perceived credibility than the however large a group of people decides on foreign policy. I think he might be somewhat out of his element. If he was sure that the WMD claims were false, and had proof, maybe it might be a different story.
But I mean, generally, following orders without asking a whole lot of questions is necessary for the military to work effectively. Someone is your superior, ostensibly, because they know more and have more experience than you. Serving in the military I would think requires a bit of faith in the people in charge of you, and that's the general mindset that is necessary. Of course it's not always true, but if everyone questioned everything we'd probably have quite a few more problems.
I'm kind of rambling and I'm not sure where I'm going with this, but it just seems these sort of overarching policy decisions are different, from an ethical standpoint, than the sort of moral decisions one would make during combat or in war. Here at school, the emphasis seems to be placed on making ethical decisions in regards to the latter.
I'll probably be transferring at the end of this year, though not for any reason so noble as taking the moral highground :/. However, I would be interested in hearing of the problems your friends have had while in the military.
This is an interesting quote I came across one day that kind of illustrates your point:
This is what is most difficult, wrote a French soldier who went to Algeria and then refused to fight, being cut off from the fraternity, being locked up in a monologue, being incomprehensible.
I recently got an a80 as well and have been very pleased with it. I'm not a big photographer or anything, but it does what I need. There's an almost full range of manual controls. You can attach external lenses as well, although I think they may need to be specially made for the a80 (not sure on this). The other thing that is kind of irritating is that it only takes jpeg's. No RAWs. But other than that, a very nice camera for the price. Oh, and no external flash.
Idiot. The net energy produced by that kind of system would be negative; it would take more energy to send 1 kg of spent nuclear fuel to Jupiter than could be produced by that kilogram. You end up consuming more energy than you generate.
I don't think that has any relevance to what he's talking about. Sending nuclear waste to other planets would prevent the environmental problems associated with the waste. Nuclear Energy has a very clean output aside from the waste and if that is all sent to space we have fewer potential environmental problems than you get when you burn coal, oil, etc.
As to your claims that it takes more energy to send one kg of waste than the potential output of that kg, I have no idea if it's true or not, but again that wasn't the point the parent was trying to make.
Why don't you not be so quick to judge next time.
The resolution won't be that high. The size of the screen is just going to be like 40' x 60'. That's just the size though, not the resolution. So really, there won't be any hit.
Yeah, but supposedly it doesn't have to be machined at all. The properties of the alloy allow it to be cast just like plastics. And they said if they needed a razor blade, they could cast it without any need for refinement because when the metal cools it doesn't shrink. So, they probably don't have to be real worried about that kind of thing.
A compound I believe. In a compound you cannot discern between the different substances that make it up and the two substances can only be separated through electrolysis. In a mixture, the two or more pure substances are discernable or rather, can be separated through physical means. Please correct me if I'm wrong.
Well eventually we're going to have to upgrade right? And even if you try and build your own computer, I thought there was something about AMD and Intel making deals with Microsoft to build this copyright stuff right into the chip? Then again, I could be wrong.
