Answers
Air pollution is the mixing of foreign substances to the whole atmospheric air. Harmful and toxic gases emitted by the industries and motor vehicles causing huge damage to the living organisms whether plants, animals or human beings. Some of the natural and various human resources are causing air pollution. However, most of the air pollution sources are stem out of the human activities like burning fossil fuels, coal and oil, release of harmful gases and substances from factories and motor vehicles. Such harmful chemical compounds like carbon dioxide, nitrogen oxides, carbon monoxide, sulphur dioxide, solid particles, etc are getting mixed to the fresh air. The level of air pollution has become increased by great extent because of 690% increase in damaging pollutants because of the expanded need of motor vehicles from last century.
Other source of the air pollution is decomposition of garbage in landfills and disposal of solid wastes which are emitting methane gas (dangerous to the health). Rapid growth of population, industrialization, increased use of automobiles, aeroplanes, etc has made this issue a serious environmental problem. The air we breathe every moment is full of pollutants going to our lungs and whole body through blood causing uncountable health problems. Polluted air is causing damage to the plants, animals and human beings in many direct and indirect ways. If the environmental protection policies are not followed seriously and strictly, the increasing level of air pollution may increase up to one million tons annually in the recent decades.
Answer:
Air pollution
Air pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole.
Air pollution is caused by solid and liquid particles and certain gases that are suspended in the air. These particles and gases can come from car and truck exhaust, factories, dust, pollen, mold spores, volcanoes and wildfires. The solid and liquid particles suspended in our air are called aerosols.
Effects On Humans
People experience a wide range of health effects from being exposed to air pollution. Effects can be broken down into short-term effects and long-term effects.
Short-term effects, which are temporary, include illnesses such as pneumonia or bronchitis. They also include discomfort such as irritation to the nose, throat, eyes, or skin. Air pollution can also cause headaches, dizziness, and nausea. Bad smells made by factories, garbage, or sewer systems are considered air pollution, too. These odors are less serious but still unpleasant.
Long-term effects of air pollution can last for years or for an entire lifetime. They can even lead to a person's death. 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. Some scientists suspect air pollutants cause birth defects. Nearly 2.5 million people die worldwide each year from the effects of outdoor or indoor air pollution.
Ways to reduce pollution
Anybody can take steps to reduce air pollution. Millions of people every day make simple changes in their lives to do this. Taking
instead of driving a car, or riding a bike instead of traveling in carbon dioxide-emitting vehicles are a couple of ways to reduce air pollution. Avoiding aerosol cans, recycling
instead of burning them, and not smoking cigarettes are others.
