Define pollution essay on thermal pollution and effects
Answers
Thermal power plant uses coal as an fuel.(2)when the coal is burnt the chemical energy in it is converted into thermal energy .(3)these energy is absorbed by water in the pipe as shown in schematic diagram ,the water converts it into steam.(4)these steam strikes with turbines kinetic energy of steam rotates turbines turbines are in contact with her erator generator converts it into electrical energy.(5)while combustion of coal many harmful gases like co2,NO3 sulphuric acide are formed by the reactions these results into global warming,air pollution,acid rains
(6)also while condensation of steam some warm and harmful gases are released
Pollution
In simple terms, Pollution refers to any unwanted and hazardous substances that is harmful to environment. Today, even kids are aware about the term 'Pollution'. There are various factors due to which pollution spreads nowadays. All this pollution occurs just because of Human activities. Humans are only responsible for pollution and it's effects.
Our Earth is getting contaminated day by day due to increase in pollution. Pollution effects the quality of life and cause serious health problems. The effects of pollution on human beings and earth aren't naked sometimes, but they can cause very serious problems to living life.
The quality of Air has been decreased due to human activities like Industrial smokes, vehicles and release of CO2 in Air from last 20 - 30 years. As Co2 is important for Human life activities, it is even more harmful too. More CO2 to the human beings can cause serious breathing problems for not human beings but also all living creatures.
There are mainly 3 types of pollution's: Air Pollution, Water Pollution, Noise pollution.
Factors because of which air pollution occurs are Industries, Vehicles, Cigarettes, Natural activities like volcanic eruption etc. Air pollution cause problems related to Heart, Lungs and breathing. More Air pollution can even cause death of living organism.
Secondly, Contaminated waste water from industries, domestic water waste, release of toxic materials etc ; are the factors due to which Water pollution occurs. Water pollution is today's serious problem. The toxic water released from industries is very harmful for the nature ; But, this same water is consumed by living beings. Due to which, there are serious health problems due to this. Due to consumption of this same water, Human beings even have serious diseases.
Thirdly, Loudspeakers, Transportation, Poor urbanization, Industrialization, Social events are the factors reasonable for the sound pollution. Due to very large and unwanted sound produced, the environment and nature is disturbed and even humans may lead to hearing problems.
To reduce pollution and it's effects, we should start it from ourselves.
To reduce Air pollution:
- We should use our Cycle for riding a small distance; it saves our money and natural resources are also saved.
- We should use bus for travelling. It reduces our expenses and it's a huge advantage to save natural resources like Fuel.
- Industrial and residential areas should be out of the city such that, the smoke released from them should not affect the citizens.
To reduce water pollution:
- Industries should save the waste water near them and by applying chemicals on it, they should convert that water into usable water.
- We should not through toxic materials and chemicals near water reservoir or sea. Which can help to maintain the environment water quality.
