　　the following appeared in a brenton newspaper.

　　the brenton power plant draws water from scotts river for its cooling system and releases the warmed water back into the river. the town council recommends that the plant install a more efficient cooling system that uses less water, claiming it will be more environmentally sound. however, in uptown, where the new system is used, a study found that the complex network of pipes in the new system tends to accumulate algae. the build up of algae can be avoided by scrubbing the pipes, which is costly, or by adding an herbicide to the water in the pipes to prevent algae accumulation. but water containing the herbicide cannot be released back into the river and it is known that low water levels can harm river ecosystems accustomed to higher levels. therefore, brenton power plant should continue to use the old cooling system exclusively.

　　the following appeared in an editorial in the seatown newspaper.

　　seatown has a large port exclusively for fishing boats, whose owners pay fees for the upkeep of the docks and for facilities for cleaning engines and repairing nets. in recent years, declining fish populations have decreased fishing revenue and forced many owners to stop fishing altogether. as a result, the port has a high vacancy rate and port managers are considering allowing pleasure boats, including cruise ships and other large vessels, to use the port in order to increase revenue. but allowing pleasure boats into the port would be a mistake, because the fishing boats would be forced out of the port. we should preserve the port for the fishing fleet, which, unlike pleasure boats, contributes to the prosperity of seatown.
