The best illustration of the concept, imo, is that with sustained 1.3%/year world population growth, we'll reach a population density of 1 person per square meter of land in only 780 years.
- redorb 16y agogive me some context; how many meters per a person are we at currently? / Then give me some focus; what will it be at in my life span... 50 years?
- kalid 16y agoJust for fun, I made a quick calc for you: http://tinyurl.com/3xl32bx http://tinyurl.com/3xl32bx In 50 years at 1.3% growth we'll basically double our population, and go from about 8000 m^2 per person to 4000 m^2 per person. After 780 years, the growth starts adding up, you can play with the numbers.
- jackowayed 16y agoWow, instacalc is pretty awesome.
- jackowayed 16y agoThe population will increase by a factor of exp(.013780) = 25336.5 So we should be at roughly 25,336 meters / person currently. (But remember that plenty of that is more-or-less unlivable--Siberia and the like.) In 50 years, the population will have increased by a factor of exp(.013 50) = 1.91554, so in the next 50 years population will roughly double, so that number will go down to about 13k meters/person.
- rjett 16y agoUsing data from the 2000 US Census, Manhattan, the United States' most dense city, had 25,836 people per square km or 0.025836 people per square meter.
- stck 16y agoThat's roughly 38 square meters per person. For the most dense city, that's plenty of space.
- robryan 16y agoAt some point though there will be some kind of event to bring this down. Might be a population number or a resource usage spot, very unlikely to the world could remain at peace as certain countries loss large chunks of people to famines ect, people that have nothing to live for wouldn't want to go down without a fight.
