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. Most (80%) of these withdrawals go to thermoelectric power plants (for cooling) and agriculture (for watering crops).

Hair Color. In general, dark hair is dominant over light. But as with eye color, your baby's hair can turn out to be a beautiful range of shades between your hair color and that of your partner. It depends on the colors, or pigments, you both have in your hair and how they mix. Parents with similar hair color may have a baby with a hue that's slightly different, but within their color range. But surprise colors can certainly appear from parents with different hair colors.
