What is pollution? Describe the causes of pollution.

(N/A) Pollution is defined as any undesirable change in the physical,chemical,or biological characteristics of air,land,water,or soil that harmfully affects human life,industrial processes,living conditions,and cultural assets.
The primary causes of pollution include:
$1$. Industrial Activities: Release of toxic chemicals,heavy metals,and particulate matter into the atmosphere and water bodies.
$2$. Vehicular Emissions: Combustion of fossil fuels in automobiles releases gases like $CO$,$CO_2$,$NO_x$,and hydrocarbons.
$3$. Agricultural Practices: Excessive use of chemical fertilizers,pesticides,and herbicides leads to soil degradation and water eutrophication.
$4$. Waste Disposal: Improper management of solid waste,including plastic and electronic waste,leads to land and water pollution.
$5$. Deforestation: Removal of trees reduces the natural capacity of the environment to filter pollutants,leading to increased $CO_2$ levels.
