This quiz had no option for alternative fuel cars, for instance, but the impact of an EV will be about 1/3 that of a comparable ICEV. It had no option as to whether you get your electricity from renewables. It had no option adjusting for HOW the meat you eat is produced. This, aside from the obvious flaws such as not accounting for children.
Interesting how if you enter in the most wasteful habits possible to mimic how the wealthy live, you get roughly 35 planets. And this doesn't account that they have homes more along the lines of 10,000 square feet, instead of 2,500+, or fly even 200 hours a year, let alone 100+. In reality, it's probably double.
$this->bbcode_second_pass_quote('', 'I')'ve seen comparisons saying that for a European average standard of living, we would be sustainable at a population level of 2.5 billion. So these numbers are roughly convergent.
Assume powerdown slightly beyond that level, i.e. to an Eastern European average rather than Western European average, and perhaps one planet could support about 3 billion humans. (After all, people in Eastern Europe still manage to eat enough and stay clean...)
Nature's got the solution for us, in the form of a dieoff of about half the population. After that, the rest is easy.
We haven't begun to increase efficiency yet, either. A 3-fold increase in efficiency of resource use, which is fairly doable, would allow 7.5 billion at the European standard. Arguably, the European standard may be higher than the American standard, but with far less consumption associated with it.
Stop all of these wars, start using currently viable renewable sources of electricity as much as possible, stop subsidizing factory farming, use more efficient appliances, replace air travel with high speed electric rail as much as feasible, among other measures that may actually increase quality of life, and we won't have near as much of a problem. We could actually have a decent living standard on almost minimal ecological footprint if the proper adjustments were made to the very products we consume, and not necessarily sacrificing these products altogether.
But we sadly are not doing such. It's more profitable to waste. The Soylent Green and then Mad Max/dieoff scenarios will make consumption the highest, precisely what some people making money want.
The unnecessary felling of a tree, perhaps the old growth of centuries, seems to me a crime little short of murder. ~Thomas Jefferson
