Akwande Dhladhla 11HM Due: 16 May 2022 Prepared Oral: Pollution “Love is in the air but the air is highly polluted.” Good day Mrs. Cathy and fellow classmates. The problems with the world today are many. One of the biggest issues in the world today is pollution, of course! You may be wondering;why would I pick the most boring and neglected topic.Well here’s why: I think all the problems of pollution are caused by human beings. There was once a point where our planet had green rich plants, clean water, and clean air and so on. Defining pollution isn’t easy but the dictionary defines it as “The contamination of one substance by another so that the former is unfit for its intended use”. Pollution comes in many different forms such as: sound, visual and air pollution. My oral will be focused on air pollution.This can not be avoided .We are all affected by this.We breathe in nitrogen and oxygen which surrounds the earth that’s also known as the atmosphere. Over the years, the amount of carbon dioxide on earth increased rapidly. Which is caused by smoking cigarettes, burning open fires, the increase of motor vehicles and factories. Carbon dioxide is one of many greenhouse gases which helps to trap heat in the atmosphere which keeps the earth warm. However, too much carbon dioxide traps in too much heat and threatens to cause climate changes. This can affect your health conditions you could experience difficulty in breathing, asthma, coughing and wheezing as well as diseases including lung cancer, heart disease and stroke. Which could lead to death. Exposure to air pollution may result to a decrease of your IQ levels. Air pollution also has negative effects on the environment. The gases released into the air by power stations and industry cause acid rain which kills trees, farmers crops and damages lakes and rivers in many countries. There are many things being done at the moment to improve our environment. Such as using control devices to help die down air pollution by using a thermal oxidizer which is a huge system that decomposes hazard gases like factory smoke and releases them into the atmosphere. Dust collector which handles heavy dusty loads in the air. People are even switching from using plastic straws to cardboard straws because plastic isn’t biodegradable.People are buying their food locally to reduce travelling distance. There are many solutions to stop air pollution. You could plant your own tree to produce more oxygen .The municipality can do a better job by collecting rubbish weekly, when they don’t collect there are more chances of people burning their own rubbish which increases the carbon dioxide in the atmosphere. Instead of travelling by car you could change and walk on foot, ride a bicycle or even take public transport. If you know anyone who smokes, you could tell them to quit smoking.Recycling also improves air quality by reducing power demand. Recycling reduces the levels of carbon dioxide in the atmosphere which is equal to taking an estimate of 5 million cars off the road. This will help reduce carbon footprint. I conclude by saying if everyone helped to improve air pollution then there would be more love in the air than pollution. BIBLIOGRAPHY Becklake, John. “Green Issues Pollution” .Gloucester Press.
