Won’t You Be My Neighbor?

Half of the world’s population lives on just 1% of the land.

This map created by Max Galka uses NASA data to illustrate where the Earth’s 7 billion+ people live today. The yellow regions of the map have a population density of at least 900 people per square mile. That’s about 3.5 billion people living in some pretty cozy quarters.

“A human being at rest runs on 90 watts,” he says. “That’s how much power you need just to lie down. And if you’re a hunter-gatherer and you live in the Amazon, you’ll need about 250 watts. That’s how much energy it takes to run about and find food. So how much energy does our lifestyle [in America] require? Well, when you add up all our calories and then you add up the energy needed to run the computer and the air-conditioner, you get an incredibly large number, somewhere around 11,000 watts. Now you can ask yourself: What kind of animal requires 11,000 watts to live? And what you find is that we have created a lifestyle where we need more watts than a blue whale. We require more energy than the biggest animal that has ever existed. That is why our lifestyle is unsustainable. We can’t have seven billion blue whales on this planet. It’s not even clear that we can afford to have 300 million blue whales.” (via http://lucasmelb.Tumblr.com + http://acidadebranca.Tumblr.com )

(via lucasmelb) A college professor once told me that MAYBE our planet could sustain 20 billion people- for a while. In the 1960’s my parents say that there were three billion people on the globe. In the year 2000, I remember reading in national geographic (while waiting forever in the lobby of my optometrist..,) that we had hit 5 billion. Now were encroaching on 7 billion.., exponential population growth with no end in sight, yet nobody seems concerned??! This has always baffled me…..(!!)
