well then, I suppose the end of our standard of living is comming, eventually.
By 2030 if I am still alive I will be 70, and hopefully blisfully unaware of how bad things have become.
there is also the possibility that things can change that we can't anticipate yet, to solve/aleviate the issue partialy.
Probably not good things either, such as massive climate change causing droughts, food
& water shortages, etc, all things that will change the numbers as the population decreases or stabilizes due to other shortages/problems. The next set of wars will be fought over clean water, not oil.
