A New Way to Understand a Billion

How many leaves change color in New Hampshire? 608 billion!
The U.S. Forest Service says that there are 666 million colorful trees in the state's forest land. Assuming the average tree has 800 leaves, each weighing a tenth of an ounce, that’s 608 billion leaves.

Other ways to define a billion:

A billion seconds ago it was 1959.

A billion hours ago our ancestors were living in the Stone Age.

700 billion dollars is the cost of the U.S. financial bailout plan. A bit more than the number of color-changing leaves in New Hampsire.
