Fresh air is the phase we use to suggest healthy living. Discussion Air is important. Plants, animals, and human beings, where able to emerge cause of the supply of oxygen generated by the earliest marine organisms over billions of years. The air is polluted because of the dusts that come from vehicles and factories. We can see people wearing nose mask. The fact that they filter out particles of dust and soot simply adds the poignancy of our urban predicament. Factories are one of the reasons why we have air pollution.
The soot that comes out from a particular factory can spread harmful chemicals that we might breathe instead of fresh air. Canals also produce air pollution because of the bad odor coming from it maybe because f the trash that gets stuck on the canals because of improper waste disposal. Air supplies us with oxygen which is essential for our bodies to live. Air is 99. 9% nitrogen, oxygen, water vapor and inert gases. Human activities can release substances into the air, some of which can cause problems for humans, plants, and animals.
There are several main types of pollution and well-known effects of pollution which are commonly discussed. These include smog, acid rain, the greenhouse effect, and ‘holes” in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment. Methods 1 . Divide students into cooperative learning groups of three to four students or have them work individually. 2. Tell each group to decide which areas they would like to test.
Many scientists did research on this particular issue and now we continue this research. Air pollution is not a gauging matter; many might have contradicted this old issue. For example back then before the industrial revolution this was not a very important topic because burning of fossil fuel like coal to power steamed engines was still to be discovered. The airs was much cleaner back then no soot no sulfur- dioxide emissions just fresh air generally air was much cleaner then as of now. What makes air dirtier now are pollutants, but first what are pollutants?
Pollutants substance in the air that can cause harm to humans and the environment is known as an air pollutant. Pollutants can be in the form of solid particles, liquid droplets, or gases. In addition, they may be natural or man-made. Pollutants can be classified as primary or secondary. Usually, primary pollutants are directly emitted from a process, such as ash from a volcanic eruption, the carbon monoxide gas from a motor vehicle exhaust or sulfur dioxide released from factories. Secondary pollutants are not emitted directly.
Rather, they form in the air when primary pollutants react or interact. An important example of a secondary pollutant is ground level ozone -?? one of the many secondary pollutants that make up photochemical smog. Some pollutants may be both primary and secondary: that is, they are both emitted erectly and formed from other primary pollutants like Sulfur oxides, Nitrogen oxides, Carbon monoxide, Carbon dioxide, Volatile organic compounds, Particulate matter, Persistent free radicals, toxic metals, such as lead, cadmium and copper, Chlorofluorocarbons, Ammonia, etc. IR pollution has bad effects on health. Air pollution is a significant risk factor for multiple health conditions including respiratory infections, heart disease, and lung cancer, according to the WHO. The health effects caused by air pollution may include difficulty in breathing, wheezing, coughing and aggravation of existing expiratory and cardiac conditions. These effects can result in increased medication use, increased doctor or emergency room visits, more hospital admissions and premature death.
