Environmentalproblems 110413211208-phpapp02

  1. 1. ENVIRONMENTAL<br />PROBLEMS<br />DEFORESTATION<br />DYNAMITE FISHING<br />CLIMATE CHANGE<br />EUTROPHICATION<br />ACID RAIN<br />
  2. 2. CAUSES:<br />*GLOBALIZATION<br />*OVERPOPULATION AND POPULATION GROWTH<br />*CORRUPTION OF GOVERNMENT INSTITUTIONS<br />*INEQUITABLE DISTRIBUTION OF WEALTH AND POWER<br />DEFORESTATION<br />the cutting down of trees or the removal of forests which is later on converted for urban use.<br />EFFECTS:<br />*EROSION OF SOIL<br />*LOSS OF BIODIVERSITY<br />*DISRUPTION OF WATER CYCLE*FLOODING AND DROUGHT<br />*CLIMATE CHANGE<br />
  3. 3. CAUSES:<br />*HUMAN INFLUENCES<br />*SOLAR VARIATION<br />*VOLCANIC ACTION<br />*ORBITAL VARIATION<br />*THERMOHALINE CICULATION<br />*PLATE TECTONICS<br />CLIMATE CHANGE<br />EFFECTS:<br />*SEA LEVEL IS RISING<br />*ARTIC SEA IS MELTING<br />*EXTREME DROUGHT IS INCREASING<br />*ECOSYSTEMS ARE CHANGING<br />refers to a long-term change in the average weather patterns over a specific region, over a significant period of time.<br />
  4. 4. CAUSES:<br />*COMBUSTION ENGINES<br />*BURNING OF FOSSIL FUELS AND OIL*SOME MINERAL ORES CONTAIN SULFUR DIOXIDE, AND THIS IS RELEASED WHEN THE MINERALS ARE PROCESSED.<br />ACID RAIN<br />EFFECTS:<br />a broad term referring to a mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids.<br />*ACID RAIN HAS BEEN LINKED WITH THE DEATH OF FISH IN PONDS AND LAKES.<br />*IT MAY ALSO CONTRIBUTE IN THE YELLOWING OF LEAF IN PLANTS AND TREES, AND THE DEATH OF TREES IN FORESTS.<br />
  5. 5. CAUSES:<br />*RUN-OFF FROM EROSION*DISCHARGE OF DETERGENTS<br />*RUN-OFF OF INORGANIC FERTILIZERS<br />*DISCHARGE OF PARTIALLY TREATED OR UNTREATED SEWAGE<br />EUTROPHICATION<br /> a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality.<br />EFFECTS:<br />*PLANT AND ANIMAL BIOMASS INCREASE<br />*TURBIDITY INCREASES<br />*ANOXIC CONDITIONS MAY DEVELOP<br />*RATE OF SEDIMENTATION INCREASES, SHORTENING THE LIFESPAN OF THE LAKE<br />
  6. 6. CAUSES:<br />*LAZINESS AND GREED OF FISHERMEN<br />*POVERTY<br />*LACK OF JOB OPPORTUNITIES<br />*IGNORANCE<br />*LACK OF DISCIPLINE<br />DYNAMITE FISHING<br />Dynamite fishing is one of the methods of catching fish. This is an activity using an explosive device that kills many fishes and other creatures under the sea.<br />EFFECTS:<br />*DESTRUCTION OF CORAL REEFS<br />*MORE ENDANGERED MARINE SPECIES*TOXIC TO HUMAN BODY<br />*LOSS OF JOBS<br />
  7. 7. PLAN OF ACTION<br />Educate myself with things that can help save the biosphere.<br />Share to others my learning.<br />Go organic.<br />Help plant trees.<br />Reduce, Reuse and Recycle.<br />
