Pollution

Natural environment: A natural environment is one that exists without significant human intervention. This includes natural landscapes like forests, deserts, oceans, and mountains. It also encompasses the natural ecosystems that exist within these landscapes.

Urban environment: While an urban environment is a type of anthropogenic environment, it's a more specific subset. An urban environment refers to a densely populated area with a high concentration of buildings, infrastructure, and human activity. Not all anthropogenic environments are urban. For example, a rural farm or an industrial park are also anthropogenic environments.

Modern environment: "Modern environment" is a broad term that can encompass various aspects of contemporary life. It's not as precise as the other options in defining a specific type of environment. "Modern environment" might include technological advancements, social changes, or global interconnectedness, in addition to the built environment.

Plastic is a polymeric material that has the capability of being molded or shaped, usually by the application of heat and pressure. This property of plasticity, often found in combination with other special properties such as low density, low electrical conductivity, transparency, and toughness, allows plastics to be made into a great variety of products. These include tough and lightweight beverage bottles made of polyethylene terephthalate (PET), flexible garden hoses made of polyvinyl chloride (PVC), insulating food containers made of foamed polystyrene, and shatterproof windows made of polymethyl methacrylate.

Asbestos is a mineral that readily separates into long, flexible fibers. Chrysotile is the fibrous form of the mineral serpentine and is the best-known type and accounts for about 95 percent of all asbestos in commercial use. It is a hydrous magnesium silicate with the chemical composition of Mg3Si205(OH)4. The other types all belong to the amphibole group of anthophyllite, amosite (grunerite), crocidolite (riebeckite), tremolite, and actinolite.

Water pollution: This refers to the contamination of water bodies like rivers, lakes, oceans, and groundwater with harmful substances. Water pollution can be caused by industrial waste, sewage, agricultural runoff, and plastic pollution.
Land pollution: This refers to the contamination or degradation of land due to the accumulation of harmful substances or improper land use. Land pollution can be caused by factors like industrial waste disposal, hazardous materials dumping, deforestation, and intensive agriculture.
Noise pollution: Noise pollution refers to excessive or unwanted noise that can disrupt the normal activities of living organisms. It can come from various sources, including traffic, machinery, construction, loud music, and even aircraft. Noise pollution can have negative impacts on human health, such as increased stress, sleep disturbances, and hearing loss.

Photochemical smog is also known as "Los Angeles smog". Photochemical smog occurs most prominently in urban areas that have large numbers of automobiles (Nitrogen oxides are the primary emissions). Photochemical (summer smog) forms when pollutants such as nitrogen oxides (primary pollutant) and organic compounds (primary pollutants) react together in the presence of SUNLIGHT. A gas called OZONE (Secondary pollutant) is formed.

Nitrogen Dioxide + Sunlight + Hydrocarbons = Ozone (Ozone in stratosphere it is beneficial, but near the earth's surface it results in global warming as it is a greenhouse gas)
The resulting smog causes a light brownish coloration of the atmosphere, reduced visibility, plant damage, irritation of the eyes, and respiratory distress.
