Pollution

  1. 1. Pollution<br />
  2. 2. Pollution<br />Pollution is the contamination of air, soil, or water by the discharge of harmful substances.<br />It is created mostly by human actions, but can also be a result of natural disasters. Pollution has a detrimental effect on any living organism in an environment, making it virtually impossible to sustain life.<br />
  3. 3. Types de Pollution<br />
  4. 4. Air Pollution<br />Air pollution is the introduction of chemicals, particulate matter, or biological materials that cause harm or discomfort to humans or other living organisms, or damages the natural environment, into the atmosphere.<br />
  5. 5. Waterpollution<br />Water pollution is the contamination of water by foreign matter that deteriorates the quality of the water.<br /> Water pollution covers pollutions in liquid forms like ocean pollution and river pollution. This type of pollution occurs in the oceans, lakes, streams, rivers, underground water and bays. It involves the release of toxic substances, pathogenic germs, substances that require much oxygen to decompose, easy-soluble substances, radioactivity, etc. that become deposited upon the bottom and their accumulations will interfere with the condition of aquatic ecosystems. <br />
  6. 6. Landpollution<br /> Soil pollution or land pollution involves the following mechanism:<br /><ul><li>deposition of solid waste
  7. 7. accumulation of non-biodegradable materials
  8. 8. toxification of chemicals into poisons
  9. 9. alteration of soil chemical composition </li></li></ul><li>Noisepollution<br />This particular pollution is increasing due to the rise in the utilization of heavy duty machineries of industrial facilities and vehicles, synonymous to the increase in the standard of living in most countries. We make sounds practically every seconds of our day, but to the extend it has reached an unfavorable high intensity which had cause many disturbances and irritation to others emotionally that has adverse effects on our daily activities.<br />
  10. 10. Radiactivepollution<br />The 40&apos;s was the era where the first nuclear bomb was being developed, and that&apos;s why it&apos;s called the nuclear era. However, nuclear energy has already researched back since 1900. Nuclear era reached its greatest peak in the world war, by showing its massive ability of destroying things. <br />Nuclear energy is a form of energy that’s released by the splitting of atoms. Since scientists have found a way to make use of the energy, it has also been used to generate electricity.<br />Nuclear energy has been recognized as a clean energy because it doesn’t release pollutants such as CO2 to the atmosphere after its reaction that could damage our environment. It&apos;s also known that nuclear energy has reduced the amount of greenhouse gas emission, reducing emissions of CO2 for about 500 million metric tons of carbon.<br />
  11. 11. Cars running around the streets, factories emitting toxic smoke, sewage being dumped into the sea, and oil being spilled into the ocean, are very common in our society. We, the human being, have caused theses pollutions at the first place, but now the pollutions have come to threaten us.Our health is deteriorated as result of emission of carbon dioxide from the vehicles, and sulfer dioxide and nitroxide from industries. These gases are often trapped in the city, creating smog that could worsen asthma, impair lung function, and even cause death. <br />
