Brown tides are growths of algae on the sea's surface that prevent sunlight from reaching marine plants below, thereby destroying not only the plants but also the shellfish that live off these plants.

Which of the following, if true, could best be used by the highway official to support the official's proposal in the face of the taxpayer's objection?
