Another Year

Another year has disappeared,
And presumably a century of million lives;
The population clock
Indicates there are 7 billion and more alive,
My calculation is,
1/70th of us have died,
Therefore a century of million lives
Have found their ends in 2012.
Per the population growth,
I'm sure,
'13 will harvest more...
Guess the number, and you win the jelly beans;
Or is it, Guess the jelly beans, and you will win the number?
Another year has disappeared,
There is no denying, so why bother lying?
