According to a study concerning environmental economics, any manufacturer that offers an environmentally sound lawnmower, such as a manual push mower, will almost certainly reap a huge profit because consumers say that they want a mower that requires neither gasoline nor electricity. A spokesman for the trade association of gasoline lawnmower manufacturers asserted that this claim had little factual support.
The last manufacturer of manual push lawnmowers just declared bankruptcy because of declining profits would best support the claim made by the spokesperson.
