Respected Principal, teachers and my dear friends, a wonderful morning to all of you. Today on this special occasion, I would like to speak some words on the topic- Air Pollution.
Air pollution is the contamination of air with harmful substances that degrades its quality. It is one of the most prevalent kinds of pollution. Causes of air pollution include burning of fossil fuels, emissions from vehicles, volcanoes and forest fires.
Air pollution leads to many respiratory diseases among humans. It is also related to global warming and climate change. This is because the greenhouse gases that cause air pollution are responsible for depleting the ozone layer. Smog caused by air pollution results in reduced visibility, which in turn prompts various accidents.
To conclude, we must try our best to prevent air pollution to preserve the quality of the air that keeps us alive! Thank you for listening to me so attentively.
