Readers discuss a recent study by University of Utah that found that the amount of gasoline needed by a reasonably efficient car to travel a single mile comes from 4 tons of prehistoric plant material.
"A staggering 98 tons of prehistoric, buried plant material is required to produce each gallon of gasoline we burn in our cars, SUVs, trucks and other vehicles." For a reasonably efficient car, riding 25 miles per gallon, this translates to 4 tons of prehistoric plants per mile, or more than two tons per kilometer. The research paper also mentions that everyday, we are using the fossil fuel equivalent of all the plants growing during a whole year just for our cars."
