Imagine living in Kolkata, India, with a population density of over 24000 people per square kilometer.

For every square kilometer there are over twenty-four thousand people.

Imagine the entire planet getting up to that point.

As food starts to run out, cannibalism will rise.

Water will be like gold. People will be murdered for water filters.

O2 levels will drop, people will lose their minds due to oxygen starvation.

Trees will be gone - need the room for more housing.

CO2 levels will skyrocket; no trees, too many mouth-breathers.

Ocean acidification will burn out all submarine life.

And once the population naturally declines, the planet will be a wasteland so destroyed, nothing will be able to regenerate. Welcome to planet Venus II.

The sun will eventually grow bigger as it uses its main hydrogen fuel source, moving onto harder-to-burn helium. Mars will be the next planet in the habitable zone. And, as history will show, human Martians will destroy that planet as well.

And life in this solar system comes to a close.

What was the catalyst for all this? High fructose corn syrup, McDonalds pink slime burgers, and reality TV.

Ah chiggady check yourself before you wreck yourself.

http://en.wikipedia.org/wiki/Population_density

"The world's population is around 7 billion,[3] and Earth's total area (including land and water) is 510 million square kilometers (197 million square miles).[4] Therefore the worldwide human population density is around 7 billion ÷ 510 million = 13.7 per km2 (35 per sq. mile). If only the Earth's land area of 150 million km2 (58 million sq. miles) is taken into account, then human population density increases to 47 per km2 (120 per sq. mile). This includes all continental and island land area, including Antarctica. If Antarctica is also excluded, then population density rises to over 50 people per km2 (over 130 per sq. mile).[1]"

i think it might take awhile to hit that 24000 per sq. km milestone
