Environmental pollution it is the entrance of any unwanted material into the natural environment, which makes it polluted, risky, and also inappropriate for use. Pollutants contain: tangible materials, in addition to sound, light, and temperatures when they enter the environment unnaturally. According to the (Pure Earth) organization concerned with environmental affairs, pollution affects in a poisonous method more than 200 million people around the world, and also indicated that the effects of pollution go beyond that. considerable pollution, and the level of intelligence of these children is about 30-40 points lesser when they pass intelligence tests (IQ) compared to normal kids, in addition to that, the average age of the residents of these places is fewer than 45 years; Because of their affliction with many sicknesses, from here the idea of reducing the problem of environmental pollution and finding solutions to it became an urgent necessity, so several efforts have been made to find radical solutions to decrease the emission of pollutants to the environment by properly managing and treating wastewater, and reducing air pollution. Effective recycling of hazardous pollutants, and other solutions.
· Causes of air pollution There are numerous reasons that lead to air pollution, and the most prominent reasons and causes for that are:
· Industrial pollutants: Industrial treatment processes, in mineral factories, smelting, paper and pulp factories, oil refineries, chemical factories, sugar factories, cotton, and rubber manufacturing plants are responsible for one-fifth of air pollution, and contain the following pollutants: Industrial chimneys for combustion of fossil fuels, which are: carbon dioxide gas, carbon monoxide gas, sulfur dioxide gas, hydrogen sulfide gas, and hydrocarbons.
· Vehicles: Vehicles are the largest sources of air pollution, as they produce approximately two-thirds of carbon monoxide emissions, and about half of hydrocarbons and nitrous oxide emissions, and vehicle exhausts also produce some gases such as lead, which have harmful effects on vital societies, and produce various volatile organic compounds that it results from the combustion of fuel in vehicles.
· Burning fossil fuels: Fossil fuels are burned to produce energy to carry out many actions such as cooking, heating, lighting, washing, and others, and it produces a variety of pollutants, including: hydrocarbons and sulfur dioxide gas. Fossil fuels, especially coal, produce about two-thirds of the sulfur dioxide emissions into the air.
Among these types of pollution, air pollution is the main type threatening the environment, humans, plants, animals, and all living organisms.
Humans impact the physical environment in several ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. These negative impacts can affect human behavior and can prompt mass migrations or battles over clean water.
At this point in earth’s physical history, our impact on the environment is so substantial that scientists believe “pristine nature,” or ecosystems untouched by human intervention, no longer exist. Some of the human activities that cause harm (directly or indirectly) to the environment on a global scale include human reproduction, overconsumption, overexploitation, pollution and deforestation, which are some of the influencing activities.
