Mint Juleps
Saturday, October 14, 2006  
I have recently talked to people who have calculated how many tons of polution people in various countries create each year. The waste is from water for washing, carbon from burning fuel, garbage thrown away, etc.

Actually a big part of the waste is the weight of the water. The total weight of all waste per person in countries differs due to lifestyle. I do not have a link to this data at the moment. However, I have decided to make a separate calculation for future comparison.

What is the weight of the waste the human body each year. It seems to me that a big part of this would be air exhaled. About every 4 seconds we take a breath. If we are not doing much, that is about an eighth of a gallon (a pint) of air. That works out to 15 pints per minute or about 2,700 gallons a day and 985,500 gallons a year.

At room temperature air weights about 0.075 pounds per cubic foot A cubic foot in turn is about 7.481 gallons, so a gallon of air weighs about 0.01 pounds or about 1/6th of an ounce.

Therefore we each breath out about 9,855 pounds or about 5 tons of waste air every year. What about water?

We consume about 4 to 5 pounds of water every day (including the water in our food) and obviously must expell about the same amount. That's about 1650 pounds or less than an ton per year.
