“Burning fossil fuels releases gases and chemicals into the air.” And in an especially destructive feedback loop, air pollution not only contributes to climate change but is also exacerbated by it. “Air pollution in the form of carbon dioxide and methane raises the earth’s temperature,” Walke says.

The EPA identified six major types of air pollutants deemed especially harmful to human health. These are carbon monoxide, sulfur dioxide, nitrogen oxides, ozone, particulate matter and lead. Since the Clean Air Act of 1970 and the identification of these pollutants, air pollution has decreased markedly.

Air pollution can also cause headaches, dizziness, and nausea. Long-term health effects from air pollution include heart disease, lung cancer, and respiratory diseases such as emphysema. Air pollution can also cause long-term damage to people’s nerves, brain, kidneys, liver, and other organs.

Essay on Air Pollution– Earlier the air we breathe in use to be pure and fresh. But, due to increasing industrialization and concentration of poisonous gases in the environment the air is getting more and more toxic day by day. Also, these gases are the cause of many respiratory and other diseases.

Air Pollutants

• Carbon Monoxide.
• Lead.
• Nitrogen Oxides.
• Ozone.
• Particulate Matter.
• Sulfur Dioxide.
• Other Air Pollutants.

Common air pollution issues are discussed below.

• 1.1 Acid Rain. The term “Acid rain” is commonly used to refer the wet (fog, rain, cloud water, snow, sleet, and dew) and dry (acidifying gases and particles) deposition of acidic components.
• 1.2 Global Warming and Climate Change.
• 1.3 Ozone Layer Depletion.

Sources of Water Pollution

• Sewage (Waste Water) Sewage is another name for waste water from domestic and industrial processes.
• Agricultural Pollution. The agriculture industry covers 76% of the land area of England and Wales.
• Oil Pollution.
• Radioactive Substances.
• River dumping.
• Marine Dumping.

Dust from places without vegetation, methane gas emitted by the digestion of food by animals, like cows and cattle, radon gas from radioactive decay, wildfires, releasing smoke and carbon monoxide into the atmosphere and volcanic activity, producing sulfur, chlorine, and ash particulates are a few examples of pollution …

The most common sources of air pollution include particulates, ozone, nitrogen dioxide, and sulfur dioxide.

Summary. Air pollution is a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it’s also called smog.

11.2 Steps of a Conclusion Examine the three steps of an effective conclusion: restatement of the thesis, review of the main points, and concluding device.

Sentence #1: restate the thesis by making the same point with other words (paraphrase). ~ Example: Thesis: “Dogs are better pets than cats.” Paraphrased: “Dogs make the best pets in the world.”

Most conclusion paragraphs are four to five sentences long and should average between 50–75 words. They should be long enough to get your point across, but short enough that you’re not rehashing every idea you’ve ever had on the subject. Conclusion paragraphs begin by revisiting the main idea definition.
