Pollution Pollution is defined as the introduction of harmful materials into the environment.It is known that the majority of environmental pollutants are caused by human activities such as the use of industrial machinery, power-producing stations, combustion engines, and cars.Land pollution occurs through the release of chemicals or the disposal of wastes, such as heavy metals, hydrocarbons, and pesticides.Lastly, machines, vehicles, traffic noises, and musical installations that are harmful to our hearing produce noise pollution.Pollutants are harmful solids, liquids, or gases that reduce the quality of our environment.While the natural sources include causes such as forest fire, volcanic erosion, dust storms, and agricultural burning.Water pollutants are industrial wastes, oil spills, farm wastes, and pesticides.Pollution has several adverse effects on animals, plants, environment, ecosystem and human beings.These materials are known as pollutants.

Pollution is defined as the introduction of harmful materials into the
environment. These materials are known as pollutants. Pollutants are harmful
solids, liquids, or gases that reduce the quality of our environment. These
pollutants can be created by human activities and by natural sources.
It is known that the majority of environmental pollutants are caused by human
activities such as the use of industrial machinery, power-producing stations,
combustion engines, and cars. Human activities have a bad effect on the
environment by polluting the water we drink, the air we breathe, and the soil in
which plants grow. While the natural sources include causes such as forest fire,
volcanic erosion, dust storms, and agricultural burning.
There are four major types of pollution which are: air pollution, water
pollution, land pollution, and noise pollution. Air pollution is determined as the
presence of pollutants in the air in large quantities for long periods. Air pollutants
are hydrocarbons, CO, CO2, NO, NO2. Water pollution refers to the presence of
pollutants in water at high levels that affect the water quality. Water pollutants are
industrial wastes, oil spills, farm wastes, and pesticides. Land pollution occurs
through the release of chemicals or the disposal of wastes, such as heavy metals,
hydrocarbons, and pesticides. Lastly, machines, vehicles, traffic noises, and
musical installations that are harmful to our hearing produce noise pollution.
Pollution has several adverse effects on animals, plants, environment,
ecosystem and human beings. It is a global issue and people are now being more
aware of the need to prevent this problem. It is vital to control pollution to prevent
its adverse effects on our environment and life in general.
