All the strive in the world got me to thinking...One of those hmm moments Okay...There's 7 billion people on the planet and I started with the surface area of the earth. Then I backed out oceans, sea, lakes, mountains and deserts. Everywhere humans can not live and came up with 1.55 X 108 square feet of living space. So that divided by 7 billion gives each person ~ 450 square feet of living space. I've doubled checked it and can't believe my answer. There's more frigging room in a 2-car garage. Let me google it to check... Nope! The google answer gives ~ 5 acres but doesn't back out uninhabitable land. Humans can't live there so I disagree with the 5 acre number and don't believe my own answer. Crap! I'm no Einstein but something's gotta give. Makes me think of George Carlin, "The planet will shake us off like a bad case of fleas." Oh Well, now that I've brightened your day, think I'll have a glass of wine and go play with the dog.
