  1. Eutrophication

  2. Eutrophication: pollution caused by the addition of nutrients; mainly nitrates, phosphates and sulfates.

  3. Examples: herbicides, pesticides, fertilizers, sewage, detergents, farm animal manure, and many industrial wastes. • Sewage being dumped into Lake Michigan in Milwaukee…happy sailing

  4. Sewage being dumped illegally and legally into the oceans and lakes and rivers via pipes

  5. Cruise lines are guilty……. • The fines currently cost less than the processing of the raw sewage to make it safe

  6. Surfers protesting the dumping • Many diseases and bacterial infections are caused by these dumpings

  7. Twenty million fewer gallons of sewage will taint the 1,624 mile California coastline starting next year. The U.S. Environmental Protection Agency announced Wednesday that it will ban all large cruise ships and other commercial vessels from discharging sewage within three miles of the state's coast. In doing so, the EPA established the largest coastal "No Discharge Zone" in the United States. "Cruise lines and the shipping industry can no longer use California's valuable coastal and bay waters as their toilet," said Marcie Keever, Oceans & Vessels Campaign director at Friends of the Earth.

  8. Third World nations don’t even police this rule and commonly use the ocean as a large toilet.

  9. Fertilzers,pesticides, and herbicides are used worldwide and have few laws controlling their use.

  10. If the workers are wearing gas masks, why wouldn’t we worry about their being put into water?

  12. Rachel Carson, the author of “The Sea Around Us” and “Silent Spring” knew of the dangers before her death in 1964.

  13. Industrial Pollution

  14. Industrial Pollution is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem i.e. physical systems or living organisms.[1] Pollution can take the form of chemical substances or energy, such as noise, heat, or light.

  15. It affects air and water and the land

  16. CHINA'S GLOBAL HUMAN RIGHTS ABUSE - OUR ENVIRONMENT China is now the world's number one polluter. China's pollutants are now a measurable part of California's daily pollution with China's brown pollution plume visible from space. A deformed child is born in China every thirty seconds. Cancer rates there have increased by 40% in the same period. Recalls include food, toothpaste, tires and toys. Death's from fake medicines have been reported.

  17. Environments are being destroyed in China. A town of 50,000 people in China's export hub has warned residents not to drink tap water after finding manganese contamination, local media said, the latest in a string of mass heavy metal poisonings to hit major cities.

  18. India is guilty and many developing countries have no pollution control laws in place.

  19. This happens worldwide

  20. Macroalgae: algae and plants found in fresh and saltwater which are large and can be seen without assistance of a microscope. • Microalgae: algae and plants found in fresh and saltwater which are microscopic.

  21. Turbidity: the amount of total suspended solids in a body of water. • Transparency: the depth or distance at which light can penetrate the water.

  22. Bacteria: prokaryotic, one celled organisms. Some transmit diseases. Most act as decomposers and break down organic compounds in the tissues of living or dead organisms using oxygen in the process.

  23. Necktonic Organisms: Marine organisms that swim freely and purposefully. • Sessile: cannot move, immobile

  24. Hardy, less desireable marine species

  25. TEST QUESTION • Please define eutrophication then discuss how it affects the following: microalgae, macroalgae, turbidity, transparency, oxygen levels, bacterial levels and various forms of marine life. • Think about change over time…months or a year.
