Smoking, cooking, burning coal or wood in the house cause indoor air pollution. If the ventilation is poor, it's even worse. In addition, active volcanos, desert storms and forest fires make air pollution. Acid rain, smog, and greenhouse effect cause air pollution. Acid rain is a mixture of sulphuric and nitric acid, which is in snow, rain and fog.
Every year, humans dispose of billions of tons of solid wastes. Most of our disposal methods cause harm to the environment. Hazardous wastes are substances released into the environment that can cause death or harm to people and their surroundings. These wastes are very hard to dispose of and usually contaminate the environment quickly. Air pollution is a severe problem, especially for the United States.
Disposal of fly ash is very hazardous to the land, creates health hazards, and creates environmental danger. When fly ash gets out into the natural draining system it results in siltation and clogs the system; it reduces the ph balance and portability of water. It also interferes with the process of photosynthesis in plants and thus disturbs the food chain. Today fly ash can be made into bricks and used as building material and was used in the construction of The American Embassy in India. Indoor air pollutants include tobacco smoke, hair sprays, perfume, glues, pesticides, parasites, fungi, formaldehyde, asbestos, and radon.
Nearly, 66,000 people were killed at Hiroshima, and many survivors died after few months because of nuclear radiation (Nuclear Weapons Effects, Pike J). Aquatic life contamination, potable water supply, and contamination of drinking water are the most challenging issues after the denotation of nuclear weapons. Aquatic life in Hiroshima and Nagasaki was destroyed and millions of animals and insects were endangered. Thousands of people were suffered from severe diarrhea caused by the contaminated water and radiation therapy and chemotherapy (Humanist, 25-32). The land for plantations and cultivations were damaged so, many people were suffered from starvations and thousands died after few months of detonation.
Household and farming chemicals: Spraying fertilizers and pesticides on plants and agricultural farms, fumigating homes, household cleaning products or painting supplies and normal insect/pest killers release harmful chemicals into the air and cause pollution. Most of the times, when we use these chemicals at home or at our offices and there is no or little ventilation, we end up falling sick when we breathe these poisonous chemicals. The effects of air pollution The effects of air pollution are acidification and eutrophication. Acidification is a chemical reaction involving air pollutants that can create acidic compounds which can harm vegetation and buildings. Sometimes, when an air pollutant, such as sulphuric acid combine with the water droplets that make up clouds, the water droplets become acidic, forming acid rain.
“In developing countries, 70 percent of industrial wastes are dumped untreated into waters, polluting the usable water supply” (NationalGeographic.com). Another cause for water pollution is sewage and water waste, which carries a lot of harmful bacteria and toxic chemical which leads to serious health problems. One of the common water pollutant is known as Pathogens, found in sewers of houses. Microorganisms in water can cause some serious diseases which then act like carriers. These carriers then form a contact with an individual and a common example of this process is called Malaria.
Due to pollution, Earth’s overall health is at risk. Entire ecosystems are being damaged and Earth’s inhabitants are in danger. Factors like improper waste disposal and lack of recycling cause harm to the planet and exponentially deteriorate the Earth into disrepair. Pollution is especially
Once the damage to the cilia and bronchi occur the lung can’t clean itself, because of this the toxic substances in the cigarette s remain contained in the lung. Due to this cancer continually develops. In addition to causing damage to the respiratory system, smoking also causes damage to the circulatory system, in organs such as the heart and the arteries. Heart attacks occur more often in smokers than in nonsmokers. According to The American Council on Science and Health smoking kills more than 400,000 Americans every year.
WHAT IS POLLUTION?? - We have heard much about pollution, and we know that it is really bad for us and all the living creatures in our ecosystem. Pollution expresses the contaminations that are removed into the environment, and of course it causes lots of harmful changes. Pollution can take place as chemical substances or energy like heat, noise, light. Pollution can be made either by human or by the nature.
Water Pollution, contamination of water by foreign matter such as micro-organisms, chemicals, industrial or other wastes, or sewage. Such matter deteriorates the quality of the water and renders it unfit for its intended uses. Effects of Water Pollution Notable effects of water pollution include those involved in human health. Nitrates (the salts of nitric acid) in drinking water can cause a disease in infants that sometimes results in death. Cadmium in sludge-derived fertilizer can be absorbed by crops; if ingested in sufficient amounts, the metal can cause an acute diarrhoeal disorder and liver and kidney damage.
