Here are some world population statistics…
7.11 billion | the global human population size at the end of September 2013 as estimated by world population clocks
the number of people added to the global population each hour
1.46 million | the number of people added to the global population each week
8.25 million | the number of people living in New York City in 2011
200 million | the number of people alive when Hannibal took his elephants across the alps to fight the Romans in 218 BC
annual average global population growth rate as a percentage of the total [United Nations estimate]
annual average population growth rate in Nigeria, equivalent to 3.94 million more people per year

annual average population growth rate in China, equivalent to 6.53 million more people per year
3.7 billion | approximate number of people living in urban areas, 52% of the total
approximate area of global urban development equivalent to 3% of the total land area
estimated land required to accommodate urban growth to 2030 [from research published in the Proceedings of the National Academy of Sciences]
global average daily energy consumption per person
land area used for agriculture — 37.9% of the total land area
time since agriculture was invented
time since industrial scale agriculture became common
1.3 billion tons | estimated amount of food wasted each year during production and consumption

World population statistics are startling. The current global population size is the largest that it's ever been and even though the speed of growth has declined, what any positive growth rate from such a large base this means for resources is huge.
What we know is that the demographic transition will happen. There is nothing in nature or our own history that says it worked. The conventional wisdom is that wealth improves child survival rates and that means fewer births are needed to make people feel comfortable with their reproductive success.
The question is how the transition will play out. Will it be through fewer births and natural attrition? Or will resources run out and the subsequent scramble increase the death rate?
Fewer births requires careful management of resources together with innovation and adaptation.
More deaths will just be ugly.
