As you know by now, our planet now has a population of 7 billion people. As fellow TreeHugger Brian Merchant put it, "That means 7 billion people who get hungry, need space, and disagree with things that the other 6.999999999 billion people say." And as Brian points out, that means 7 billion people who want electricity, to drive cars, who want clean water, internet access, etc.
But what does 7 billion actually look like?
This great infographic by Fathom, appropriately titled Dencity, shows us. Larger dark circles show fewer people while brighter circles have a denser population. You can get the infographic for just $30 as an educational tool or quite possibly an act of depression.
Nonetheless, Fathom does a great job of displaying the situation we are in. We hit 7 billion just twelve years after hitting 6 billion, and 24 since we hit 5 billion. This growth is being driven primarily by the developing world. For example, Africa's population, which just passed 1 billion, is expected to double come 2050.
Beijing is the largest city in the world, with over 17 million people. In fact, China is home to six of the world's most populous cities. Kinda scary, huh?
And as expected, the East Coast is America's most densely populated region.
