Just in Time for Christmas: Seven Billion Humans
The Earth isn’t any bigger than it was during the 1960s, but if researchers are correct, Santa Claus will have twice as many households to visit this year as he did in 1961, when John F. Kennedy announced that an American would set foot on the moon before the decade's end.
The U.S. did beat Kennedy’s deadline for a lunar landing, on July 20, 1969, but humanity is no closer to setting up residential centers on outlying orbs; so estimates that global population will pass 7 billion before 2011 ends raise some practical questions.
Where will all these people live? (Mostly developing nations, in Africa and elsewhere.)
What will all these people eat? (Not so much.)
Does the Earth circulate enough clean water to go around? (Not as of now.)
Will these 7 billion humans make responsible birth-control choices? (Look for 15.8 billion people by 2100.)
So, is this perceived excess of consumer creatures any concern of yours, or is it just everybody else's problem?
If you're the type who wants to make things better for yourself, and for everyone else, choose a solution from the United Nations Population Fund—it suggests 7 Billion Actions.
