  1. 1. Gergov, Nikolay Minkovski, Martin Kolev, Dimitar
  2. 2. <ul><li>It is the process of which a small amount of closed air bodies become full of nutrients(6) </li></ul><ul><li>The enrichment is gradual(6) </li></ul><ul><li>There can be artificial and cultural eutrophication. In the artificial, human influenced nutrients help the plants to burst into growing(5) </li></ul><ul><li>There can be an algae boom and while the plant live is growing rapidly the animal life is choking, because there is not enough air for them(5) </li></ul>
  3. 4. <ul><li>For eutrophication, besides nutrients is needed is light and heat, artificial, and natural(6) </li></ul><ul><li>The naturally rich of nutrients ponds or lakes that are affected by the eutrophication are called eutrophic.(5) </li></ul><ul><li>Eutrophication is not always bad, because it basically emphasizes for the water’s richness and fertility. (5) </li></ul><ul><li>However, it can be dangerous for the organisms living under the lake because if the nutrients gained are human's and the lakes takes more nutrients than its limit this may result in suffocation.(5) </li></ul>
  4. 5. (3) - Citation
  5. 6. <ul><li>When phosphates are added to the water the algae start to grow vastly, consuming more oxygen and reducing this from the fish inside.(7) </li></ul><ul><li>The algae dies and bacteria are using oxygen to decompose the algae.(7) </li></ul><ul><li>Eventually there is more bacteria using more oxygen to decompose the algae(7) </li></ul><ul><li>When the bacteria die they release phosphates, bursting the growth of algae and forming a cycle.(7) </li></ul>
  6. 7. (4) - Citation
  7. 8. <ul><li>PEOPLE </li></ul><ul><li>OTHER LIVING ORGANISMS </li></ul><ul><li>Eating fish from water polluted with algal blooms may result in serious illness and even death(2) </li></ul><ul><li>Causes economic damage to coastal communities who are dependent on fish sale.(2) </li></ul><ul><li>The lack of dissolved oxygen in the water causes many species to die, including fish.(1) </li></ul>
  8. 9. <ul><li>An algal bloom is a sudden and quick increase in the population of algae in a water body.(1) </li></ul><ul><li>It may occur in freshwater and also marine environment(sea, ocean)(1) </li></ul><ul><li>Algal bloom concentrations may go up to millions of cells per milliliter.(1) </li></ul><ul><li>Simply: When more algae and plants grow, other organisms die.(1) </li></ul>
  9. 10. 1 and 2 (Citation)
  10. 11. <ul><li>Algal blooms occur due to the excess of nutrients, especially nitrogen and phosphorous into water bodies.(1) </li></ul><ul><li>The high concentration of these nutrients cause a rapid increase of algae and green plants.(1) </li></ul><ul><li>The problem is that with the increase of algae, more organisms die.(1) </li></ul>
  11. 12. <ul><li>The dead organic matter in the water bodies serves as food for decomposers and in this case bacteria.(1) </li></ul><ul><li>The available resources cause more rapid spread of bacteria in the water body(1) </li></ul><ul><li>The bacteria consumes the dissolved oxygen which is vital for fish and other living organisms, thus leading to their eventual death.(1) </li></ul>
  12. 13. <ul><li>When there is more algae or bacteria that decomposes it, more oxygen is needed for them, so they cause low oxygen levels in the water, suffocating the animals in it.(1) </li></ul><ul><li>There is massive spread of plants and algae due to the excess of nutrients which is not only negative because the plants can also serve as supplies for the people.(1) </li></ul>
  13. 14. <ul><li>The extreme amounts of fertilizers in the Gulf of Mexico or the so called “Dead Zone&quot; from the Mississippi river cause the death of almost all organisms in the area.(3) </li></ul><ul><li>The developed eutrophication there threatens the ecosystem of total obliteration because the extremely low levels of dissolved oxygen are not enough to keep the fish and other living organisms alive.(3) </li></ul>
  14. 15. (5) - Citation
  15. 16. <ul><li>Many nutrients, including phosphorous and nitrogen are washed into the sea from ships and also from industrial wastewaters(4) </li></ul><ul><li>In addition the air deposits of nitrogen also contribute for the occurrence of Eutrophication(4) </li></ul><ul><li>Due to eutrophication many living organisms, mainly fish, die and this harms the economy of all countries who have a bounder with Baltic Sea(4) </li></ul><ul><li>The most polluted area is the Gulf of Finland(4) </li></ul>
  16. 17. (6) - Citation
  17. 18. <ul><li>One way is to reduce the natural run off and so keep the level of nutrient concentration below the normal level (8) </li></ul><ul><li>Another way is to prevent the erosion because when the soil is washed a way a lot of nutrients appear (8) </li></ul>
  18. 19. <ul><li>Clean the water body from algae and all the other plants that suck up the oxygen out of the water (9) </li></ul><ul><li>Decrease the fertilization of areas close to water bodies. Industrial agriculture and deforestation cause erosion which contributes to the creation of eutrophication significantly(9) </li></ul>
