1. Types of pollution
is the introduction of contaminants into a natural environment that causes instability, disorder, harm or discomfort to the ecosystem ie physical systems or living organisms. Pollution can take the form of chemical substances or energy, such as noise, heat or light.is a major problem all around the world. It has adversely affected the lives of millions of people and caused many deaths and health disorders. Pollution is contamination by a chemical or other agent that renders part of the environment unfit for intended or desired use. Natural processes have released toxic chemicals into the environment throughout the history of the earth. Currently, the pollution generated by human activities presents the most serious problem.are basically 3 types of pollution. They are:
). Air pollution;
). Water pollution;
). Land pollution; of the major causes of the pollution crisis are as follows :). Deforestation - for the establishment of factories, industries and due to urbanization in various parts of the world, trees are cut on a large scale without any adequate efforts to plant new trees. This leads to deforestation, which has caused a rise in the pollution levels and distortion of natural order.). Polluted rivers - The wastewater and liquids from plants and factories are linked with nearby river water, which are polluted when they release disposal from these units. People in Developing/Undeveloped countries also pollute rivers by using the water in these rivers for washing clothes, utensils, bathing and other activities. Oil spilled from ships pollute oceans around the world.). Sound pollution - the machines used in factories make noise throughout the day, and this disturbs the peaceful atmosphere in the vicinity, as machines used without proper covering lead to sound pollution. It puts heavy mental strain on the people staying in the nearby areas. Noise is the most pervasive pollution in America.). Air Pollution - each year industrially developed countries generate billions of tons of pollutants. Many pollutants come from directly identifiable sources; sulphur dioxide, for example, comes from electric power plants burning coal or oil. Others are formed through the action of sunlight on previously emitted reactive materials (called precursors). For example, ozone, a dangerous pollutant in smog, is produced by the interaction of hydrocarbons and nitrogen oxides under the influence of sunlight. Ozone has also caused serious crop damage. The increasing of number vehicles have also lead to an increase in air pollution, due to the harmful gases like Carbon Monoxide emitted from these vehicles. Gases generated in the chemical plants also cause air pollution. People suffer because of smoke and bad smell from the industrial units particularly from chemical plants.). Soil pollution - dumping of wast...
