Population

    Today we talked about population and settlement.  There are over 7 billion people in this world.  It took 10,000 years to get to 1 billion people, and it happened in 1804.  Then, 123 years, in 1927, the world reached 2 billion.  In 1960, 33 years, we reached 3 billion people.  After 14 years, we reached four billion in 1974.  13 years later, in 1987, we reached five billion.   In 1999, we reached 6 billion.  Finally, in 2011, we reached seven billion.  
     As you can see, we started off slowly.  It seemed to get faster every year, and it could go even faster.  It could even double, to a whopping 14 billion people.
     There are about 2 people born every second, so the population can get bigger.  It probably will.  I wonder how big the population will be in the 22nd century.
