1/4 of the word uses 3/4 of the world's resources.
Well, how on earth do you quantify that?
Easiest is GDP, wikipedia says 65% of GDP belongs to MDCs
Resources are not the same as production. Basically all you're saying here is that developed countries produce more goods than undeveloped countries...which they then use. Which, aside from being obvious, doesn't really support the spirit of the position being asserted here.
Imagine if you and I are both neighbors, and we each own one acre of land with 10 apple trees. I collect apples from 8 of my trees, cut down two and build a house out of the wood, then plant 4 more apples trees. And you collect apples from two trees and sleep under a tree. I "produced" more, and I "used" more. But it would be very strange to look at this and say that I "used up" more of the available resources. Next season there will be more apples, and in a few years I'll have more apples trees than you do. That fact that I "used" more isn't a problem.
There are very few resources that aren't replenishable. Water, air, food, wood...these things are all easily replenishable. With only a few exceptions, metals are not in particularly short supply. Roughly 30% of the volume of planet earth is composed of iron, for example. Titanium and aluminum are about 1% each. That's approximately 60,000,000,000,000,000,000 metric tons each, and metals are recyclable. It's silly to think we're in danger of running out. There are some relatively scarcer materials, but civilization would not come to and end if we ran out of yttrium, for example.
Running out of things like coal or gasoline would just mean that we'd need to more solar/geothermal/wind/etc. There's no real problem here.
Finally, those of you complaining about the "horrible, evil rich people" who are "wasting resources" on luxury goods, gold, diamonds, etc...what exactly are you even complaining about? If we somehow magically ran out of gold, do you seriously think that would be a problem? Yes, there are some industrial uses for these things. Spacecraft use gold foil, some drills use diamond, etc. But it's not like space travel or industrial drilling is going to just stop for lack of materials because people used up all the gold and diamonds making watches.
I'm not seeing what the problem is
Agreed. I don't see a problem.
