Explanation:
Air pollution means the presence of pollutants in the atmosphere is such concentration that causes injury to human being, animals and plants.
Air pollution is the name for anything that makes the air dirty. Thus, air pollution is anything that contaminates the air and makes it harmful to breathe for humans, animals and birds.
Water pollution means contamination of water with physical, chemical or biological properties of water due to discharge of industrial effluent or any other liquid, gases or solid substance into water which is harmful for public health of commercial activities or in agriculture.
Sources: Domestic waste water and dirty municipal waste or sewage are the chief source of water pollution. Also read, major sources of water pollution.
Effects: Water pollution has had effects on human life. Water are polluted in different sources such as by gases, dirty soil, minerals, humans’ materials, dead body of animals and other living organisms.
Solution: Water pollution can largely be controlled by proper treatment of domestic and municipal effluents. Domestic water and sewage can rightly be mixed with soil which will increase fertility. The industries must not discharge toxic water in the land. Also read, different ways to prevent water pollution.
Soil pollution mainly occurs through agricultural chemicals. These are pesticides and fertilizers. These pesticides directly or indirectly injure other animals and human being.
Reasons: Land-ship, volcanic eruption, very strong wind current, torrential downpour, etc. are the natural phenomena which may partly contribute to creating soil pollution. The chief reason of soil pollution lies in the multifarious activities of man.
The contaminated sweepings and all sorts of refuses and garbage of the industrial establishment and of homes and homesteads, various types of chemicals and radio-active left-over etc., mainly cause soil pollution.
Radioactive pollution refers to the presence of unwanted and undesired radioactive substances that radiates ionizing radiation in the environment and its surroundings. Such radiation is very harmful for the environment.
One of the greatest problems of modern times is the sound or noise pollution. It refers to the presence of excessive sound or noise in the environment. It is often harmful for human and animal health.
Noise pollution is caused by large industries, vehicles such as cars, buses and lorries, etc. Besides these, the periodic sounds of hammering connected with some construction or repair work can be quite maddening.
Loud speakers blaring film music during festive occasions and speeches at political rallies or some other obscure cause add to the cacophony. The silence we so desperately long for seem unattainable.
Light pollution is caused by excess light contaminating the dark sky and making it artificially light.
Causes of light pollution: Lights that are left on – in both commercial premises and private residences – throughout the night are key causes of light pollution.
Effects of light pollution: Light pollution can disrupt the habitats of animals who rely on natural cycles of light and darkness to tell them when to wake up and when to rest. It can cause stress and disrupted sleep to humans. It can also make stargazing and astronomy difficult due to blocking out starlight.
Control measures: Turning lights off at night-time and installing street lamps that do not scatter light up towards the sky will help to control light pollution
