Air Pollution * Pollutants enter the air from various sources‚ but burning of fossil fuels contributes the most to air pollution. * Exhaust fumes from vehicles contains soot (tiny carbon particles)‚ lead (from cars using unleaded petrol)‚ carbon monoxide‚ oxides of nitrogen and hydrocarbons due to the incomplete combustion of fossil fuels. * Burning of fossil fuels in the combustion engines of vehicles and electrical power stations also releases large amount of carbon dioxide into the

I am here to write on behalf of the starving children around the world whose cries go unheard‚ the countless animals dying across this planet because they have nowhere left to go.

From pollution of air and water to the reduction of the ozone layer‚ after centuries later‚ we are still finding out the full weight and damage that the industrial revolution has caused. As our knowledge of our impact on the planet and the growth of our environment‚ we are still continuing to take steps to back
