The Human Race
In the seconds it takes you to read this sentence, 24 people will be added to the Earth's population.
Before you've finished this letter, that number will reach 1000. Within an hour...11,000. By day's end ... 260,000.
Before you go to bed two nights from now, the net growth in human numbers will be enough to fill a city the size of San Francisco.
It took four million years for humanity to reach the 2 billion mark. Only 30 years to add a third billion. And now we're increasing by 95 million every single year.
No wonder they call it the human race.
