Environmental Crisis and Sustainable

G.E. -Contemporary World

1. Environmental Crisis and Sustainable Josefino T. Larena Jr. ,CPS,MPA

2. Learning Outcomes Discuss the origins and manifestations of global environmental crises Relate everyday encounters with pollution,global warning desertification ,ozone depletion,and many others with a larger picture of environmental degradation Examine the policies and programs of governments around the world that address the environmental crisis

3. The World’s leading Environmental Problems 1. The depredation caused by industrial and transportation toxins and plastic in the ground. Changes in global weather patterns ( Flash,foods,extreme , snowstorms and the spread of deserts) Overpolulation Mining

4. The World’s leading Environmental Problems Waste disposal catastrophe due to the excessive amount of waste ( from plastic to food packages to electronic waste) The destruction of Million year old ecosystems and the loss of biodiversity ( Destruction of the corals reefs and massive deforestation Deadly acid rain as a result of fossil fuel combustion ,toxic chemicals from erupting volcanoes

5. The World’s leading Environmental Problems The depletion of the ozone layer protecting the planet from the sun’s ultraviolet rays due to chlorofluorocarbons in the atmosphere Urban development : DESTROYING FARMLANDS,increasing traffic gridlock Pandemics ad other threats to public health

6. Man- made Pollution The major difference between natural and man-made air pollution is that continuous or temporary natural events cause natural air pollution, but human activities are responsible for man-made pollution. We can't prevent natural air pollution from sources like volcanoes, but we can reduce man-made pollutants and their consequences: respiratory diseases, acid rain and global warming.

7. Air Pollution Air pollutants are gases and particles that harm people or other life, damage materials or reduce visibility. Some air pollution comes from volcanic eruptions, forest fires and hot springs, but most is the result to human activities. Power plants, factories, cars and trucks emit carbon dioxide, carbon monoxide, hydrocarbons, sulfur dioxide, nitrogen dioxides and particulate matter that consists of fine particles suspended in the air. Burning oil, coal, gasoline and other fossil fuels is a major cause of man-made air pollution.

8. Air Pollution Other man-made sources of air pollution include: waste disposal dry cleaning paints chemical manufacture wood stoves flour mills

9. Air Pollution Effects Natural and man-made air pollution harm humans, other life and the environment. Particulate matter from burning wood and fossil fuels lodges in lungs, causing respiratory problems, and settles in a fine film over buildings, trees and crops. Carbon monoxide interferes with the blood's ability to transport oxygen and causes headaches, heart damage and death. Sulfur dioxide, which is a product of burning coal, irritates eyes, damages lungs and makes rain acidic. Acid rain damages buildings and forests and kills aquatic life. Another contributor to acid rain is nitrogen dioxide emitted by vehicles, industrial boilers and other industrial processes. Lead from leaded gasoline, power plants and metal refineries contaminates crops and livestock and causes brain and kidney damage.

10. Global Warming Greenhouse gases that cause global warming have increased 31 percent since preindustrial times. Carbon dioxide and other gases trap heat in the atmosphere, causing global temperatures to rise. Although carbon dioxide has natural sources, such as volcanic eruptions, human activities have caused an increase from 280 parts per million before the development of industry to 370 parts per million today. Other greenhouse gases include methane and nitrous oxide -- which human activities also produce -- that have contributed to a 0.6 degree Celsius (1 degree Fahrenheit) increase in the global air surface temperature in recent decades. Particulate matter from vehicles, factories, fires and eruptions cools the atmosphere, but researchers at the National Center for Atmospheric Research still predict a 90 percent chance that human activities will cause a 1.7 to 4.9 degree Celsius (3.1 to 8.9 degree Fahrenheit) increase in global temperatures by 2100.

11. CATCHING UP AND GETTING REAL with the Climate Crisis  A crisis of this scale can only be tackled by the whole of society acting together through government. But governments, in particular, will need to do more than ‘sell’ their green policies, one by one, to the public opportunistically on the basis of their incidental benefits or of hiding their cost. They will need to make a strong, bold, courageous, effort to get out there and explain, proactively, to the public the depth and horror of the crisis we are in, the frightening magnitude of the threat we face and of the changes that we, collectively as a society, will need to make. They will need, in effect, to ‘get real’ with the public. They will probably never do that unless somebody else begins to do it, first.

12. Illegal logging the harvest, transportation, purchase or sale of timber in violation of laws. The harvesting procedure itself may be illegal, including using corrupt means to gain access to forests; extraction without permission, or from a protected area; the cutting down of protected species; or the extraction of timber in excess of agreed limits.

13. Mining Mining  is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit. These deposits form a mineralized package that is of economic interest to the miner.
