of people getting viral hepatitis, cholera, typhoid fever and many stomach

and intestinal diseases from eating bad shellfish or swimming in areas with

high levels of bacteria. In 1993 beaches were temporarily closed over 2400

times in the Unites States because of high bacterial levels (Raw Sewage, On-

line). Many U.S. states monitor bacterial levels in the water and a few others

do not and there are many cases of sickness. The problem of unmonitored

bacterial levels is not as obvious in first world countries as in the third world

countries. There are many outbreaks of disease because of the

underdeveloped governments do not monitor the levels of bacteria.

Industry shapes the life of every person on this planet. The goods we

buy are from industry and about everything we owned is manufactured in one

way or another. These industries are vital but the vastness in which they

pollute is amazing. Acid rain is formed when acids such as sulfuric and

nitric acid react with water vapor in the air. Then when it precipitates this

acid falls to the ground or water. When the precipitate hits the ground it will

run into a body of water and if not directly then eventually in to the ocean.

The effect that acid rain has on the ocean is devastating it kills fish by

poisoning them. The direct discharge from factories release many types of

untreated toxins into the ocean. Some toxins that are released are PCB’s,

chloroform, arsenic, lead, and mercury. These toxins cause aquatic life

forms to die. Also in one case Beluga whales, which are 1/3 fat, absorb the

toxins into their fatty tissue and into there milk, which is fifty percent fat, and

passed to the calves (Beland, 46). This cause many deaths to young Beluga

whales and to other marine mammals. Fish also readily absorb mercury

which causes them to be unfit for human consumption. Power plants that use

water to boil and turn a turbine to produce electricity release this water after

it has been boiled with limited cooling and the hot water disrupts the marine

life around the outlet.

Proper application and choice of pesticides would reduce the amount
