Pollution refers to the introduction of contaminants into the natural environment and causing great changes in the functioning of the environment. There are various forms of pollution. These include; air pollution, which is the release of chemicals in the atmosphere; light pollution, which refers to trespass by light; littering where people throw fabricated objects in the inappropriate places; noise pollution; soil pollution, and water pollution. Causes of pollution include motor vehicle emissions, oil refineries, coal fired power plants and chemical plants. Soil pollution is caused by heavy metals and noise pollution is caused by motor vehicles, which produce unwanted noise. Pollution mainly affects development of trees and other plants, human …show more content…
Air pollution affects human beings in that it causes reduced efficiency in the functioning of the lungs. It can also cause irritation of the eyes and the throat. It has been reported that air pollution has increased the rate of asthma attacks in people. Some people also experience wheezing and coughing. There is also an increase in the likelihood of one contracting respiratory diseases such as bronchitis. Due to air pollution, there are many incidences of people experiencing headaches and dizziness. Other effects of air pollution are cardiovascular problems, cancer and premature death. (Goldsmith & Lars, 1977). Water pollution also has effects on human beings. For instance, drinking polluted water causes water borne diseases. Other effects of drinking polluted water are increased cases of typhoid, amoebiasis, ascariasis and people having hookworms. There are diseases that come along with swimming and drinking contaminated beach water. These diseases include rashes, pink eye, hepatitis, diarrhea, vomiting and stomachaches. Chemicals in polluted water such as pesticides, hydrocarbons and heavy metal (Goldsmith & Lars, 1977) also affect people. These conditions caused by such chemicals are cancer, hormonal problems that lead to interruption in reproductive and developmental problems, damage to the Central Nervous System, damage to the liver and kidney; there are also effects to an unborn baby or even death in
Disease caused by pollution might be caused by water pollution or air pollution, this is when the environment around a person is dirty. Examples are: Rickets, anemia,
Drinking contaminated water can cause different types of cancers and also infertility and birth defects due to of the presence hazardous chemicals. Impoundments that have not been built or properly closed off have led to the death of many animals and also health issues in
While, the water is contaminated humans, animals, and plants would be ill. If they drink that contaminated water for awhile they could end up
This contaminated water could cause serious health problems in those who drink it. Local reporter Keelee Hurlburt writes, “Swimming in and drinking contaminated water can cause skin rashes and health problems like cancer, reproductive problems, typhoid fever and stomach sickness in humans.” These are very serious health problems that have the possibility of eventually leading to death. USGS researchers Diane Noserale and Martin Risch state, “The White River and Fall Creek near Indianapolis had high percentages of fish with mercury levels above the safety standard.” Because the amount of mercury in the White River exceeds the safety standard, it has the potential to be harmful to anyone who consumes it.
I have seen instances where some of my colleagues have become sick from drinking tap water around the city. No matter where it is such as at their schools such as Pensacola State College or the University of West Florida, at their homes, or in public spots such as restaurants people have noticed that the water is extremely unsanitary. A quote from the DailyFinance article portrays this exactly “Of the 101 chemicals tested for over five years, 45 were discovered. Of them, 21 were discovered in unhealthy amounts. The worst of these were radium-228 and -228, trichloroethylene, tetrachloroethylene, alpha particles, benzine and lead.
Some other negative impacts of air pollution on the residents of southern California include a variety of temporary symptoms such as difficulty breathing, headaches, runny noses, and itchy eyes, as well as the development of more severe and chronic ailments such as heart disease and asthma. Asthma is one of the most prominent health issues that air pollution incites within the human body. It is highly probable that Asthma is a direct result of air pollution, although absolute evidence has not as of yet been provided to support this idea. More substantial evidence has, however, expressed the magnification of asthma that air pollution initiates within those that are already afflicted with the disease.
Drinking water sources have been contaminated with explosive methane, as well as other dangerous substances, such as benzene and arsenic, that can cause cancer and other serious illnesses. Toxic chemicals, as well as erosion and runoff from drilling operations, have fouled
Wastes deposited by the animals can introduce nutrients and disease-causing organisms into the water, posing problems for aquatic organisms as well as human populations that use the water.” Another way that humans can negatively impact the water quality is by fertilizers and pesticides being put into the water. When this happens it can make the nitrogen and phosphorus levels increase which can be lethal to the organisms in
Too much chemicals in the water like lead, sulfur, chloride and fluoride can cause birth defects, cancer, Flu like symptoms. The chemicals in the water are supposed to provide a level of sanitation to the water. The issue with this though is that the chemicals added cannot be taken out of the water people drink. Every community has a water sample chart for what goes into their water. This was create by the federal government to provide the population with info about what is in the water.
About 71 percent of our planet Earth is covered by water, and the majority comes from the oceans (about 96.5 percent of all Earth’s water). It remains as the most expansive, diverse, and mysterious places on planet Earth. But it is being threatened by the pollution by people and nature itself. By polluting the habitat of marine organism will indirectly affect the ecosystem of the marine life. Marine life is dying and as the result the oceanic ecosystem is threatened.
Pollution is the introduction or release of substances or energy that decrease the quality of the marine environment. Many pollutants are toxic of harmful to marine life (Castro and Huber, 2010). South Africa is known around the world for being one of the most diverse marine environment in the world, with 83% of the known fish families residing in South Africa (Van der Elst, 2007). There are also many marine species that are endemic to South Africa, which means they are only found in South Africa. Almost 30% of the South African population lives on the coastline (Taljaard et al. 2006), which has led to the urbanization of the coastlines and which then led to the industrialization of these areas.
Marine pollution such as presence of organic matter in the ocean can result in the condition known as hypoxia or oxygen depletion and this can have adverse effect on the marine life including plant and animals and fish. Death of these fish can result in loss of millions of US dollars that are generate from the fishing industry. Marine pollution can also result in presence of foul smell resulting from the decomposing sewage being directed to the ocean and this has the effects to hinder recreational activities taking place in the sea as well as cause discomfort and breathing problem to the surrounding population (Laura, 11).marine pollution can also result in danger to human health. The human swimmers and water sport lovers can become endangered by swimming in the polluted marine waters (Laura,
CHAPTER 1 1. INTRODUCTION The air we respire contains mixture of natural and man-made chemical, physical and biological elements that modifies ambient air quality. Among all air pollutants, the most threatening for human health include particulate matter and gaseous pollutants such as carbon monoxide, ozone, nitrogen dioxide and sulfur dioxide (WHO). The movement of people into urban areas and the growth of industry within these areas has carried more people into contact with air pollution than any other time in recent memory.
• Pollution: Pollution of air, water and soil require millions of years to recoup. Industry and motor vehicles exhaust are the number one pollutants. Heavy Metals, nitrates and plastic are toxins for pollution. While water pollution is caused by oil spill, acid rain, urban runoff; air pollution is caused by various gases and toxins
There are many problems that threatens society and one problem in particular, air pollution is a problem that threatens everyone. Air pollution is the contamination of air with pollutants that are harmful to humans, animals, and the environment. It began to be a problem when humans discovered the uses of fire and then the amount of air pollution exponentially grew after the industrial revolution, and is still a problem even today. The largest causes of air pollution are from human activities such as burning of fossil fuels and gas emissions from manufacturing plants. There are ways that ordinary people can help contribute to prevent air pollution and or else face the dangerous consequences of polluted air.
