Oh, you are not looking well, this is due to pollution. Well, what is pollution? Stinking的trash？smoke? noise? Yes, all these things and much more pollution is anything that makes the earth unhealthy and dirty. Air, water and soil are all affected by pollution. Let's understand each type of pollution one by one at first, air pollution. Air pollution happens when the air gets dirty. We cannot break primary in dirty air. Smoke from cars, industrial chemicals, wildfires and volcanoes make air dirty. The smoke released from burning fossil fuel is also in major cause of air pollution. IT includes oil, coal and natural gases. A large number of industries are also causing the release of industrial smoke and dangerous gases like carbon monoxide, hydro carbons, organic compounds, farm ful, kinnick in more from the mills and factories to the environment. Air pollution is also the reason of increases in global warming because of increasing atmosphere temperature due to the vast increasing level of Greenhouse gases. These Greenhouse gases again cause the Greenhouse effect IT forces the glaciers to melt, sea levels to increase and our climate to change. Air pollution is one of the major causes of cough, asma, burning eyes, and also some lethal diseases like cancer from kato s. Heart attack, kidney . diseases. Now we will learn about water pollution. IT is the worst and most dangerous form of pollution. Water pollution is the contamination of water bodies. Water pollution happens when dirty particles, substances or chemicals that make water contaminated are discharged indirectly or directly into the water bodies. Pollutants get into water mainly by human causes or human factors. Oil is also a big pollution . for polluting the water leaked oil from the ship or other modes flows to the cr ocean and affects the whole water. There are some other reasons to for water contamination, like leaching of rocks, decay of organic matter, decay of dead matter, sitting oil rotation and more water pollution also affects the population and entire functioning ecosystems that live in the waters. Some substances used by farmers to kill pester weeds seep into the ground and make the ground water unfit to drink. Dirty water may cause skin disease. And a rex sia, decency and a biases and more, drinking dirty water is very hazardous to your health. Now we will learn about soil pollution. Soil pollution . is the destruction of the earth. Land surfaces. IT is caused by solid waves and chemicals. Land is getting polluted through the toxic substances released by the use of chemical fertilizers, insecticides, pesticides, industrial waves and more. Not only this, the radioactive pollutants from some sources like nuclear reactors, hospitals, explosions and more, go very deep into the soil and remain there for a long time and cause soil pollution. All of the soil containment is getting mixed into the further land, and IT causes a variety of health disorders such as respiratory illness, bronchitis, cancer and asma. Many environmental groups, our governments and ordinary people are working to control pollution. Here is your chance to take care of our world. Are you ready for the initiative? Let's understand some steps for controlling pollution. If the weather is good and you do not have too far to go, you should consider walking or riding your bike. Organic vegetables and fruits are grown by farmers who avoid using harmful chemical pesticides. We should consume these more. You can avoid buying stuff which becomes waste. Never use open fires for disposal of waste, especially plastic and chemicals. Trees are very important to prevent pollution. They clean the air, provide oxygen and beautify your surroundings. IT is said that if we heal the earth, we heal ourselves. Measures should be taken on an individual basis. Thanks for watching. Stay tuned for more videos.
