A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature‚ the change in temperature decreases oxygen supply‚ and affects ecosystem composition

Air contains a variable amount of water vapor‚ on average around 1%‚ while air content and atmospheric pressure varies at different layers‚ air suitable for the survival of terrestrial plants and terrestrial animals is currently only known to be found in Earth’s troposphere and artificial atmospheres. Air is made up of 99% nitrogen‚ oxygen‚ water vapor‚ and inert gases. Nowadays‚ the air we breathe is contaminated with harmful chemicals that
