7 Billion

“But we don't take up as much space as you'd think. Standing
shoulder to shoulder all 7 billion of us would fill the city of Los
Angeles. So it's not space we need – it's balance.”

To me this means we need to be smart about our population, and
not get greedy with the amount of the world each one of us takes 
up. It's a reminder to our race that our population will always be
growing, and that we can have the space as long as we remain
aware that we are growing, and prepare for it intelengently.

9100000000% of the world doesn't have clean drinking water.
26600000000% of the world doesn't have adequate sanitation.

I feel bad for people in the world living like that that don't have a
choice or an opporunity to make a better live for themselfs. However
I do not feel bad for those who have no clean water or no adequate
sanitation that do nothing to make the world a better place, and have
never really had to try in life. They, and they alone, don't deserve
what those who try deserve.
