World population is now 7 billion

This year marks the 7th 'billion-person' milestone in the planet's history. According to the U.N Population Fund, as of Oct 31, there will be 7 billion people sharing Earth's land and resources.

And according to reports Nigeria has 168 million people.

But this makes me wonder, just one person has over 2billion or more in his account, thats not counting other potentials and yet there are people suffering on every continent. Hmmmmm......
