In a move that some suggest is taking "going green" to an extreme level, Chicago's O'Hare Airport is looking to utilize goats to keep their lawn and green space trimmed.

Worried about rising costs of fuel and the effect that pollution from the current mowers is adding to the economy, officials from the busy airport are looking to buy 30 goats and a herder to help out.  The areas that would be served by the goats is outside of the runaway area, so  observers say that animal rights organizations wouldn't have objections.

Apparently Chicago wouldn't be the first city to pilot a program like this;  Similar arrangements exist in San Francisco and Atlanta.
