Is our growth sustainable?

This just doesn't address the issue of over-population though.

According to Wiki., the birth rate is approximately 2.5 times the death rate this year. Modern science and technology is keeping people alive and alive longer. Once a cancer cure is found then the difference could really blowout. There is a survival mechanism in all organisms but the impact of mind on natural balance is seemingly uhhh not natural.

Annual births peaked at 173 million in the late 1990s, and are now expected to remain constant at their 2011 level of 134 million, while deaths number 56 million per year, and are expected to increase to 80 million per year by 2040.

It will be either self inflicted or microbial attacks which reduces population up the road ahead.
