Water pollution is a global plague that affects the people, animals, and plants. These life forms need water to survive. The causes are contributed greatly by the human population. Recently, laws have been passed to protect the precious drinking waters. Although they are in effect, most are ignored or loop holes have been found by major corporations so they can still "legally" dump harmful waste near water supplies.
There are several factors that causes water pollution. One of the reasons that the water pollution problem is so severe is that it is not actually illegal to dump pollutants into water bodies. Sewage, sludge, garbage, and even toxic pollutants are all dumped into the water. Often, governments either do not care or simply look the other way. Across the world, about half of all sewage is dumped into water bodies in its original form. No efforts are made to disinfect the sewage or to remove especially harmful pollutants. Even if sewage is treated, problems still arise. Treated sewage forms sludge, which is sent out into the sea and dumped. Many cities and countries dump sewage out at sea. Often, they place it not far from their own coastline, often killing all the sea wildlife in the dumping area. In addition to sewage, chemicals dumped by industries and governments are another major source of water pollution. Another dangerous cause is oil. Oil, such as that spilled by transport ships, has been dumped into the water. "Every year, between 1 and 10 billion tons of oil are spilt, killing many species and destroying the ecosystem in the area. Clean-up efforts have been weak, as only about 10% of the oil is removed by the most successful efforts" .
The direct effect of oil spills is
Bibliography: Exposure to very loud sounds that are enjoyable, and not technically noise to the listener can lead to hearing impairment. A survey of hearing was tested among youngsters between the ages of 6 and 19. They found that 1 out of 8 of them suffered a noise-related hearing problem. Teens attend dances, equip vehicles with systems, and even work in loud fast food restaurants. Noises are especially bothersome at night when one is trying to sleep, which is vital to good health. Noise from snowmobiles, jet skis, and supersonic jets has also intruded on the environment, affecting animals’ abilities to communicate, protect their young, and mate. MENTALHEALTH: Noise pollution is not believed to be a cause of mental illness, but it is assumed to accelerate and intensify the development of latent mental disorders. Some of these cases would be: anxiety, stress, nervousness, nausea, headache, emotionally instability, argumentative, sexual impotence, changes in mood, and increase in social conflicts. The news media regularly report violent behavior arising out of disputes over noise which in many cases these disputes ended in injury or death. SOCIAL HEALTH: Noise is a prominent feature of the environment including noise from transport, industry, and neighbour’s. Exposure to transport noise disturbs sleep in the laboratory, but not generally in field studies where adaptation occurs. Noise interferes in complex task performances, modifies social behavior and causes annoyance.
