Water pollution needs to be stopped. Pollution of lakes rivers, streams, and oceans has been killing land and water animals for years. Polluting water is a horrible act and will be stopped.
Water pollution kills all kinds of animals every year. Just the EXXON VALDEZ oil spill near anchorage Alaska caused over 3,000 otters to die 36,000 different kinds of seabirds were killed and over 100 eagles. Oil spills are one of--if not the worst types of pollution. They happen most often in the ocean and then get spread around by tides and currents where they enter streams and rivers and cover everything. They kill life and pollute more in a short amount of time than pesticides and human waste combined in about 1 year. (See graph on page 2 for more inf.) Radioactive Waste is a very serious problem polluting the lakes and oceans. Submarines release some radioactivity into the water. If a submarine ever crashed enough radioactivity would be released to destroy a region of about 300 sq. miles (this happens because of the nuclear engines) Human waste is when people dump their.... deification in the water and have sewer lines leading to water which also pollutes a lot (little streams lead to big lakes). Human waste is also when we dump garbage in the ocean because we cannot find places on land to dump it.
Some more types of pollution are.. Infectious Gases, Plant nutrients that can simulate growth of aquatic plants which then interfere with water uses and, when decaying, deplete the dissolved oxygen and produce nasty odors. Exotic organic chemicals including: pesticides, various industrial products, detergents. petroleum, inorganic materials, nuclear power plants, industrial sites, medical and scientific use of radioactive materials.
Water pollution was originally caused by need of space (to dump trash). I can say that the major sources (in general) that cause water pollution are: Municipal, Agricultural, and Industrial....
