Coral Reef Destruction Illegal Mining Waste Management Environmental laws Is the process of which marine life were taken over by illegal activity. Environmental Issues What are the causes of Deforestation 1. Illegal logging
2. Mining
3. Oil and gas extraction
4 Cattle ranching
5. Agriculture: Cash crops •Philipines have lost 90% of its rainforests! 46 species are endangered, and 4 were already eradicated completely. Only 3.2percent of total rainforest has been left. *If the current rate of deforestation continues, the world's rain forests will vanish within 100 years- causing unknown effects on global climate and eliminating the majority of plant and animal species on the planet* What are the consequences of deforestation Environmental Impact 1.Extinctions
2.Habitat fragmentation.
3.Soil erosion
4.Changes in watershed geomorphology.
5.Desertification (dry, hot, arid conditions).
6.Edge effects can change microclimates (small climates) which affect endemic species (native species which can only live in specific environmental and habitat conditions).
7.Climate change
8.Pollution Social Impact 1.Loss of culture
2.Displacement of people (loss of farmland, forest resources, etc).
3.Social conflicts and struggles over land and natural resources.
4.Conflicts over racial and ethnic rights.
5.Poisoning from oil and mining waste.
6.Economic uncertainty How to STOP/LESSEN Deforestation 1. •Always use both sides of paper when writing, drawing, photo-copying, faxing, etc. 2. •Recycle paper, cans, glass, and plastic. 3. •Buy paper products made from recycled paper 4. •Use pencils until they are stubs! 5. •Encourage your parents, relatives, and friends to buy furniture and wood that is Certified. 6.•Buy organic fruits and vegetables. 7. •Encourage your parents, relatives, and friends to drive fuel efficient cars that get good gas mileage 8. •Save electricity by turning off lights Destructive Fishing Poison Fishing Poison fishing is the use of chemical or plant substance sprayed into the water to kill fish or marinelife, or make them temporarily unconscious. Poison fishing is destructive because every time a poisonous substance is sprayed into the water, various forms of marine life in the nearby area, including all the corals, are destroyed.
using poisonous substances while fishing can damage up to a 5 meter diameter area of coral reef. The most common type of poison used in poison fishing is called sodium cyanide. Sodium cyanide fishing causes the destruction of thousands of hectares of coral reefs every year. Explosive Fishing Explosive fishing is also known as dynamite fishing or blast fishing. It uses chemicals that explode water to kill fish or marinelife. Explosive fishing is destructive because it can make a hole up to 5 meters in diameter in the coral reef. Although the fish inhabiting the coral reef can be easily caught by means of blast fishing, the explosion can cause external damage to the coral reef. It will take about 100 years for the coral reefs to regenerate leaving fish and other marinelife without place to find shelter and food. The effects of coral reef destruction are: 1. Coral reefs protect the land from storm and tidal surges.

2. Coral reefs are probable sources of medicines to cure the diseases that currently run rampant across the earth.

3. Coral reefs absorb carbon dioxide and use it to form their shells BACOOR, Cavite, Jan 10 (PIA) -- Six fishermen were arrested January 5 by members of the Bacoor Bantay Dagat Patrollers (BBDP) after receiving information on the illegal activity and caught the suspects red-handed. Six fishermen held for dynamite fishing The six arrested fishermen were detained at the Bacoor police station in Barangay Talaba for violation of Republic Act 8850, otherwise known as the National Fishery Law (NFL).

Dynamite fishing, an illegal method used by some fishermen, is one of the prohibited acts under the said law. BBDP recovered from the arrested fishermen four bottles of improvised dynamite. Handling and Disposals Hazardous wastes are poisonous byproducts of manufacturing, farming, city septic systems, construction, automotive garages, laboratories, hospitals, and other industries. The waste may be liquid, solid, or sludge and contain chemicals, heavy metals, radiation, dangerous pathogens, or other toxins. Health Effects Toxic wastes often contain carcinogens, and exposure to these by some route, such as leakage or evaporation from the storage, causes cancer to appear at increased frequency in exposed individuals. Disposal facilities are usually designed to permanently contain the waste and prevent the release of harmful pollutants to the environment Organic wastes can be destroyed by incineration at high temperatures; however, if the waste contains heavy metals or radioactive isotopes, these must be separated and stored, as they cannot be destroyed. Proper Disposal Methods 1.Most chemicals may not be put into the sewage system.

2•Some classes of chemicals may be neutralized and then disposed of down the drain with large amounts of water.

3.Most chemical waste may not be disposed of in common garbage.

4.Burning waste solvents is illegal.

5.Disposing of waste solvents, paints, varnishes or other chemicals in the back yard or in an empty lot is against the law. The materials used by most conservators can be broadly grouped into chemical classes. solvents (including paints and varnishes), detergents, acids and alkalies, bleaches and ethyl ether. Solvents
Solvents, as a class, present a known fire and health hazard and accordingly also present disposal and storage problems. Detergents
Only detergents can be safely and legally disposed of down the drain without prior treatment. Acids and Alkalies may be disposed of in the sewer system under certain conditions. If the acid or base does not contain dissolved heavy metals, it may be neutralized and then washed down the drain with plenty of water. Acids can be neutralized with sodium bicarbonate (baking soda). Alkali can be neutralized with acetic acid (vinegar). Acids and Alkalies Ether.
-Ether, diethyl ether and ethyl ether all refer to the same material.

-Petroleum ether (pet ether) is not the same chemical and is handled like the solvents.

-Ether is terribly dangerous because it is highly flammable and a terrific explosion hazard.

-Ether reacts with air to form shock sensitive explosive peroxides.

-Bottles of ether contaminated with peroxides have been known to explode from unscrewing the lid. Dry Waste
Disposal of solid or dry waste is difficult to discuss in general terms, but as a rule solid or dry materials should be kept in that state and not mixed in with liquid waste Recycling The illegal process or business of extracting ore or minerals from the ground. Deforestation the cutting, clearing, and removal of rainforest or related ecosystems into less bio-diverse ecosystems such as pasture, cropland, or plantations (Kricher, 1997). is waste material that can cause death, injury or birth defects to living creatures. Toxic Waste Cause of Illegal Mining Illegal mining is acknowledged to be one of the major causes for coal fires. Effects of illegal mining Toxic waste can be a very harmful effect of illegal mining. If the mining sites are near bodies of water chemicals can also poison the water and the fish. Fertile land can also be affected, land can become very hard and dry Boiling toxic waste can cause burns on people living near the mining sites. is the collection, transport, processing or disposal, managing and monitoring of waste materials. Solid waste management is a system for handling all of this garbage; municipal waste collection is solid waste management, as are recycling programs and dumps. Solid Waste Management - Causes and Control Measures CAUSE The main sources for solid wastes are domestic, commercial, industrial, municipal, and agricultural wastes. EFFECT Health Hazard Environmental Impact If solid wastes are not collected and allowed to accumulate, they may create unsanitary conditions. If the solid wastes are not treated properly, decomposition and putrefaction may take place, causing land and water pollution when the waste products percolate down into the underground water resources.
