Indeed, ancient human settlements are frequently recognized by their wastes—shell mounds and rubble heaps, for instance.Pollution was not a serious problem as long as there was enough space available for each individual or group.
However, with the establishment of permanent settlements by great numbers of people, pollution became a problem, and it has remained one ever since.
Modern society is also concerned about specific types of pollutants, such as noise pollution, thermal pollution, light pollution, and plastic pollution.
Great efforts are made to limit the release of harmful substances into the environment through air pollution control, wastewater treatment, solid-waste management, hazardous-waste management, and recycling.
Unfortunately, attempts at pollution control are often surpassed by the scale of the problem, especially in less-developed countries.
radioactivity) to the environment at a rate faster than it can be dispersed, diluted, decomposed, recycled, or stored in some harmless form.
The major kinds of pollution, usually classified by environment, are air pollution, water pollution, and land pollution.Through the 19th century, water and air pollution and the accumulation of solid wastes were largely problems of congested urban areas.But, with the rapid spread of industrialization and the growth of the human population to unprecedented levels, pollution became a universal problem.Air Quality Index The Air Quality Index is a way for the government to alert people to the quality of the air and how bad the air pollution is in an area or city.They use colors to help you determine if you should go outside. Anytime you can use less energy, like electricity or gasoline, it can help reduce air pollution.By the middle of the 20th century, an awareness of the need to protect air, water, and land environments from pollution had developed among the general public.In particular, the publication in 1962 of focused attention on environmental damage caused by improper use of pesticides such as DDT and other persistent chemicals that accumulate in the food chain and disrupt the natural balance of ecosystems on a wide scale.Noxious levels of air pollution are common in many large cities, where particulates and gases from transportation, heating, and manufacturing accumulate and linger.The problem of plastic pollution on land and in the oceans has only grown as the use of single-use plastics has burgeoned worldwide.Modern society is also concerned about specific types of pollutants, such as noise pollution, light pollution, and plastic pollution.Pollution of all kinds can have negative effects on the environment and wildlife and often impacts human health and well-being.
