The United States Geological Survey estimates that (as of 2005, the most recent year for which data is available) we withdraw 410 billion gallons of water a day, including both fresh and saline water.

Level 2 is the second darkest hair color level. It is usually used to describe a natural black, and is the natural color of most people who have naturally black hair along with Level 3, soft/light black hair. Refer to the hair color chart.

There are very few adults how retain a very light blond/blonde hair color, naturally. I will use the gender neutral word blond from here on in.
