Moreover, it takes around 500-1000 years (Lapidos, 2007) to biodegrade for common plastic bag. Also, some people think, plastic bags can be easily decomposed by burning it. But there is no truth in these words. When you try to decompose bag by burning it, there are a lot of toxins being produced during the process, and these toxins do a great harm not only to air which people and animals breathe, as well for Earth’s ozone layer, when there are more and more
It would result in services being unable to reach areas due to the flooding and many more lives could potentially be lost. Human factors however, are huge in earthquake hazards. The main human factor is the fact that we have settled near/on fault lines and live in areas that we know are vulnerable to earthquakes. Along with this there are issues such as building on reclaimed land which can lead to liquefaction and whole areas are destroyed due to being unsafe to live in. This also leads to fires starting which add to the death toll.
We voraciously consume resources, pollute the air and water, tear down natural habitats, introduce species into areas where they don’t belong and destroy ecosystems to the point of causing millions of species to become endangered and, all too often, go extinct. Air Pollution The human health effects of poor air quality are far reaching, but principally affect the body's respiratory system and the cardiovascular system. Individual reactions to air pollutants depend on the type of pollutant a person is exposed to, the degree of exposure, the individual's health status and genetics. Water Pollution Contamination or pollution of water affects global health in many ways. For example ingestion of poorly treated water can cause Diarrhoea, Cholera, Stomach infections and Typhoid.
Toxic waste, poisonous materials such as mercury, dioxin, PCBs, PAHs, and radioactive materials are being released onto our ocean floors causing contamination amongst the plants and animals whom live there. (“Marine Pollution causes and consequences,” 2003) The contamination of these plants and animals steer to health concerns such as lesions on marine life and other major health issues even death. (“Marine Pollution causes and consequences,” 2003) Fujita (2003, p. 4) The contamination of marine life has becoming a major concern for the safety of humans who consume seafood. Toxic waste dissolves into organisms, which are harmful and are passed along the food chain and eventually ending up in our seafood. (“Ocean Pollution,” 2002) This process is called Biomagnification, each time the animals are eaten by another animal the toxins intensify and the levels of toxins increase becoming more and more harmful even deadly for humans.
However, living in a big city is more dangerous for life and health than living in a smaller one due to a high density of population and criminal acts. A large amount of inhabitants may cause bad health conditions of the people living in megalopolises. First, there is a high level of spreading of communicable diseases, because such diseases could be caught by the air, by germs, which breed in big quantities in public transport and in places of public resort, by water. For example in New York, there was a very dangerous disease called West Nile virus. The reason of the virus emerging was standing water.
In addition to disruption in the national economy, a damage to private and public properties also contributed to the overall economical effects of hurricane Katrina. The economy of the country was slow down significantly due to hurricane Katrina. . Hurricane Katrina: Environmental Effects The environmental damages and threats on public health were the longest-lasting effects of hurricane Katrina. The industrial wastes, oil spills, household sewage, toxic chemicals and other hazardous pollutants had swept to the directly hit areas as well as neighboring regions.
One type of pollution is air pollution that is caused by factories, and carbon monoxide given off by cars. Another type of contamination is water pollution which is caused by sewage, natural disasters, and man-made garbage being tossed in to the bodies of water. One country that’s been highly effected by pollution is Kabwe a town in Zambia, Africa. Kabwe has to deal with pollution in ways that seem odd to the everyday life of Americans. Pollution has had an enormous impact on Kabwe; even breathing is toxic for the people.
In cities such as Los Angeles and Mexico City smog is a constant problem. Children, elderly people or people with asthma often get sick from breathing dirty air. There have been new developments in our understanding of the holes in the ozone layer and in our scientific studies of the spreading risk of ozone depletion. CFC’s and chlorine are known for destroying the ozone layer. Chemicals that are in the air cause different hazes.
“Noise & Noise Pollution.” Abstract: No one on earth can escape the sounds of noise – an unwanted, disturbing sound that causes a nuisance in the eye of the beholder. Noise is a disturbance to the human environment that is escalating at such a high rate that it will become a major threat to the quality of human lives. In the past thirty years, noise in all areas, especially in urban areas, have been increasing rapidly. There are numerous effects on the human environment due to the increase in noise pollution. In the following paper, the cause and effects of noise pollution will be presented in some detail.
There are many factors that are responsible of the destruction of the environment. Air pollution is one of the factors in the destruction of the environment. We have smoke that comes from cars’ exhaust, which is dangerous for human health by causing lots of disease like lung and skin cancer, respiratory problems like asthma. Also there is a chemical product or gas emission caused in the air by factories. That emission destroys the environment by reducing the ozone layer.
