What is Environment pollution?

Environment pollution is a term that refers to all the ways that human activity harms the nationalenvironment. Most people have witnessed environmental pollution in the form of an open garbage dump

or a factory pouring out black smoke. However, pollution can also be invisible, odorless, and tasteless.Some kinds of pollution do not actually dirty the land, air, or water, but they reduce the quality of life for

people and other living things. For example: noise from traffic and machinery can be considered forms of

pollution.

Environment pollution is one of the most serious problems facing humanity and other life forms

today. The relationships among all the living and nonliving things in an environment make up anecological system, called an ecosystem. Factories make products that people use and enjoy, but industrial

processes can also pollute. Pesticide and fertilizers aid in growing large quantities of food, but they also

poison the soil and waterways.

Types of Pollution

Air pollution is the contamination of the air by such substances as fuel exhaust and smoke.According to the World Health Organization, about one-fifth of the worlds people are exposed to

hazardous levels of air pollutants.

Outdoor air pollution, Each year, hundreds of millions of tons of gases and particulates pour into

the atmosphere. Most of this pollution results from the burning of fuel to power motor vehicles and heat

buildings.

Acid rain is a term for rain and their precipitation that is polluted mainly by sulfuric acid and

nitric acid. These acids form when gases called sulfur dioxide and nitrogen oxides react with water vaporin the air. These gases come chiefly from the burning of coal, gas, and oil by cars, factories, and power

plants.

Chemicals called chlorofluorocarbons (CFCs) are pollutants that destroy the ozone layer in the

upper atmosphere.

The greenhouse effect is the warming that results when the earths atmosphere traps the suns

heat.

Indoor air pollution is occurs when buildings with poorly designed ventilation systems trap

pollutants inside.

Water pollution is the contamination of the water by sewage, toxic chemicals, metals, oils, or

other substances. It can affect such surface waters as rivers, lakes, and oceans, as well as the water

beneath the earths surface, called ground water.

Soil pollutionis the destruction of the earths thin layer of healthy, productive soil, where much of

our food is grown.

Solid waste is probably the most visible form of pollution.

Hazardous waste is composed of discarded substances that can threaten human health and the

environment.

Noise pollution comes from such machines ass air planes, motor vehicles, construction machinery,

and industrial equipment.
