This seems a bit of a distraction to me. Not that I'm saying that it's not important that we chance our lifestyles (and not just because of their ecological impact), but the population issue is going to bite us in the arse either way. How much resources each individual uses is only going to affect the speed at which disaster looms, not the fact of it's looming. Even if each individual on earth were only being allocated the minimal amount of resources needed to stay alive, there would still be a limit to how many humans the finite resources of our planet can support, and (as is the nature of exponential growth) we'd still find ourselves hitting that limit far quicker than any of us can imagine.Sisifo wrote:...In my case it's not the overpopulation what makes me despair. It's the change of lifestyle. We talk that population grows exponentially, but also individual consume grows exponentially. Food (fast food and restaurants), garments (damned fashion), transportation and energy... All that is pressing our planet and our species to the cliff edge...
Or put it this way. If we could (hypothetically) get the total human population into a sharp decline over the next few years, then we might just get away with retaining our wasteful lifestyles (although that would be not excuse to do so). On the other hand, if we all (again hypothetically) started embracing a minimal waste lifestyle over the next few years, we'd still have to do something about population.
Sorry Sisifo, but population remains the elephant in the room whichever way you look at it.
Any human being (like any other organism) uses a certain minimal amount of resources. The Earths resources are finite. - It's a simple matter of mathematics.
