g01 9/8 p. 28 Watching the World *** ‘Overpopulation’
a Myth?""Amazing as it may seem, the entire population of the world can be housed in the U.S. state of Texas," reports Vitality magazine. According to the article, the current United Nations estimate of the world’s population is about six billion people, and Texas has a land area of some 262,000 square miles [680,000 sq km]. The amount of living space per person would therefore be more than 1,217 square feet [113 sq m]. "A family of 5 would thus occupy more than 6,085 square feet [565 sq m] of living space. Even in Texas, that’s a mansion," says Vitality. "Meanwhile, the rest of the world would be completely empty, available for all of mankind’s agricultural, manufacturing, educational, and recreational activities!"
Texas = 268,581 square miles (262,000)
1 square mile = 640 acres
640 * 268,581 = 171,891,840 acres
6 billion people / family of 5 = 1,200,000,000
171,891,840 / 1,200,000,000 = 0.14 acres per family of 5
Of course the logistics of conveying away the waste of 6 billion people in such a small area and providing clean water and the ability to travel is not addressed.
I bet he thought the WTS came up with these figures.
