  1. 1. Environmental Education Kate Hydn P. Nantes
  2. 2. Definition • Is contextualizing environmental issues within the physical. Biological, social, economic, historical, and cultural imperatives of the Philippines.
  3. 3. Objectives • Environmental education can be attained in terms of the learners’ awareness, knowledge, attitudes, skills and participation in the resolution of environmental problems, issues and concerns.
  4. 4. Environmental education must be: 1. Action oriented. It should involve oriented finding solutions to real environmental problems and issues; 2. Experiential. It should use variety of approaches and environments; 3. Future-oriented . It must be concerned with the present and the future.
  5. 5. 5. Holistic. It must deal with the natural and man-made aspects of the environment. 6. Interdisciplinary. It must relate to all disciplines; and 7. Issue-oriented. It must deal with local, regional, national, and global perspectives.
  6. 6. Environmental Problems, Issues, and Concerns in the Community Environmental problems in developed and developing countries worldwide are among the most important concerns facing people and their governments. These problems include population growth; poverty; deforestation; pollution of water, air, and soils; waste disposal; and loss of species.
  7. 7. Ecosystems in the Philippines
  8. 8. Biodiversity in the Philippines is unique. This means many of the life form that are found in our country are found nowhere else in the world. A key to understanding this uniqueness is the knowledge of the habitats ecosystems where these plants and animals are located.
  9. 9. AGRICULTURAL ECOSYSTEM  Agricultural is said to be the “backbone” of our country’s economy since the most Filipinos depend on farming. Natural farming and tilling of the land or soil is more recommendable than using high yielding varieties because it can preserve the environmental ecosystem. Using chemicals and fertilizers threatens the soils’ ability to recycle nutrients and good materials for plants. Killing the healthy soil, they also burden the farmers because of expensive cost.
  10. 10. CORAL REEF SYSTEM  Philippines has some of the richest and most diverse coral reefs in the world. If left disturbed, the animal populations of the reef will increase in number. The reef ’s provides recreation and tourism opportunities due its magnificent beauty. Taking good care of the coral reef ecosystem is essential.
  11. 11. FRESHWATER ECOSYSTEM Water is life. All living creatures depend on it. Clean water means clean ecosystem as a whole. Once a body of water is polluted, the living things within will die and those which or who depend on them will also be affected. Human beings will also suffer because of their life depends on water; drinking, bathing, washing clothes and other cleaning activities.
  12. 12. FOREST ECOSYSTEM  A healthy forest ecosystem is “productive”. Productivity means efficient use of the natural resources or materials available in the system without external inputs ad without leaving behind any harmful effects . The importance of ecosystem are: 1. They are habitats for diverse species. 2. Provide raw materials for pharmaceutical products. 3. Provide raw materials for breeding higher-yielding strains.
  13. 13. MARGINAL ECOSYSTEM  Are people-induced ecosystems. Usually occurring in the circumference of other ecosystems, these are converted systems of forests, cropland, and coastal areas.
  14. 14. MANGROVE ECOSYSTEM  Are located in saltfish water and muddy portions of the coastline where the freshwater from the rivers and saline water from seas meet. It provide food and shelter to various marine organisms from its prop roots.
  15. 15. SEAGRASS ECOSYSTEM  Are called the meadows of the sea. They are the source of food for plant-eating animals such as seacows or dugong, sea urchins, turtles, and other fishes.  The shady effect of seagrass protects the organisms from strong sunlight and temperature and salinity fluctuations. It also acts as nurseries for the very young fishes and ensure the sustainability of fish product.
  17. 17. URBAN ECOSYSTEMS  Refers to the loci of human activities.
  18. 18. POLLUT ION
  19. 19. • Defined as the alteration of our surroundings, wholly largely as a product of man’s action, though direct or indirect effects of changes in every pattern of chemical and physical constituent of organisms.
  20. 20. Classification and Sources of Pollution
  21. 21. Air Pollution Is defined as physical and chemical alteration of the properties of air, which is harmful to human health, vegetation and animal.
  22. 22. Major Types of Air Pollution a. Outdoor Pollution is a type of pollution derived from the mixture or collection of additional loads of chemicals produced by natural components of the atmosphere, thereby, producing harmful effects to living.
  23. 23. Sources of Outdoor Pollution • Burning of fossil fuel for power consumption • Photochemical and industrial smog • Volcanic eruptions • Forest fire
  24. 24. b. Indoor Air Pollution a type of pollution derived from the accumulation or build up of chemicals inside the office, building, houses, school, commercial store and are harmful to health.
  25. 25. Effects of Air pollution  Air pollution is responsible for major health effects. Damage of Human Health  Lung cancer  Chronic bronchitis  Depletion of ozone layer  Damage of plants that lead to dehydration and inhibition of photosynthesis
  26. 26. Air Pollution - Solutions 2 Types of Air Pollution Control oInput Control, involves preventing a problem before it occurs, or at least limiting the effects the process will produce.
  27. 27. 5 Major Input Control Methods 1. 2. 3. 4. 5. Restrict population growth Use less energy Improve energy deficiency Reduce waste and Move to non-polluting renewable forms of energy production.
  28. 28. o Output Control, this method of control seeks to fix the problems caused by air pollution.
  29. 29. The Clean Air Act (Taken from the Primer on the Clean Air Act of DENR) • Republic Act No. 8749 known as the PHILIPPINE CLEAN AIR ACT, is a comprehensive air quality management policy and program that aims to achieve and maintain healthy air for all Filipinos.
  30. 30. Water Pollution • The physical or chemical change in the surface and ground of water caused by pollutants that affect living organisms.
  31. 31. a. Major sources of water pollution Point source – a source of pollution that discharges pollutants into bodies of water to specific location. Non-Point source – a source of pollution that are widely scattered and discharges pollutants over a large sea.
  32. 32. b. Water pollution-causes Dumping of sewage Garbage Sludge Toxic waste from houses, industries and even government.
  33. 33. Land Pollution • Refers to the presence of any solid waste in the land that is injurious to the health of human beings, animals and other living organisms. Solid waste takes up space and produces unpleasant smell.
  34. 34. Causes Overpopulation Overproduction of non-biodegradable materials Medical waste Household waste
  35. 35. Solid waste and Its Disposal • Landfills, designed to reduce the amount of waste that leaks out into the environment. • Incineration, the process of reducing solid waste by burning it first. • Ocean Dumping, discharge of waste in the ocean
  36. 36. Nature Biodegradable waste and Non-biodegradable • Biodegradable waste, compostable and waste can be reused as feeds, fermentable, fuel and fertilizers. • Non-biodegradable waste, they factory waste returnable and can serve as potential sources of livelihood projects.
  37. 37. 4r’s 1. Reduce, avoid wasteful consumption goods. 2. Reuse, items that are useful instead of throwing them away 3. Recycle, the process whereby portions of these waste are sorted out and used for something of benefit. 4. Repair, reusable items to make them functional rather than throwing them.
  38. 38. Noise Pollution • is the disturbing or excessive noise that may harm the activity or balance of human or animal life.
