“Well Con, as I had mentioned to Chet, look at the way world population has increased. In all of human history it took us until 1800 to reach a billion people. Now we have 9 billion. And we are expecting it to be 10 billion in 2050. If the population continues at its current rate, by the year 2855 it has been estimated that there will be about 20 people per square foot of land and sea on this planet. Of course our species would self destruct long before we got to that number!”
“With that many people where would you go on vacation?”
