Landfill Space
If the U.S. stopped recycling and buried all of its municipal trash for the next 100 years in a single landfill that was 30 feet high, how much of the nation's land area would this landfill cover?
Correct Answer
If the U.S. stopped recycling and buried all of its municipal trash for the next 100 years in a 30-foot-high landfill, it would cover 0.06% of the nation's land area. More realistically, the actual area in use will be an order of magnitude smaller because (a) the U.S. recycles, burns, or composts 48% of its trash, (b) landfills can be more than 200 feet high, (c) after 30 to 50 years, landfills are often covered and used for purposes such as parks, golf courses, ski slopes, and airfields. Despite these facts, media outlets have been reporting for more than 30 years that the U.S. is "nearly out of space" to dispose of trash. Hence, a scientific survey shows that 66% of voters believe the correct answer to this question is more than 5%.
