- And what land area is used for this calculation? Lands that you
- consider worthless? Your backyard? Mine? Are we to _force_ people
- to have landfills near their homes so that other people have the
- _freedom_ to be wasteful?

- Let's do the arithmetic. 500 million tons of waste per year in the
- U.S. assuming a density of 1.0 comes to 500 million cubic meters.
- Suppose it is piled 25 meters high. This comes to 20 million
- square meters per year, or 20 square kilometers. The area of the
- U.S. is 3 million square miles or 23 million square kilometers.
- It will take a million years to cover the country with trash.
-
- If we do nothing special for 100 years, we will use up 1/10,000 th of
- the country. 100 years from now our descendants will be as much more
- technologically capable than we are, as we are compared to the people
- of 100 years ago.
