The Topic today is Air Pollution, and here to talk about is a very young and handsome environmental scientist at the University of Malaya, Dr. Hamiddey Esa. Good morning and welcome, Dr. Hamiddey.
Dr. H : Good morning Hisyam.
Hisyam : Shall we start now Doctor?
Dr.H : Yes, why not.
Hisyam : Ok. My first question, what is air pollution and what causes it? Dr.
H : Well, Hisyam, air pollution means that there is something in the air that we don’t want. As you know, the air we breathe already contains several gases such as oxygen, carbon dioxide, nitrogen and a few other gases. The problem of air pollution comes when unwanted chemicals chemicals are released into the air. Hisyam : Unwanted chemicals, Doctor? Can you give me an example? Dr.H : Well ozone is one example. Ozone is a poisonous gas that can cause breathing problems.
It’s very bad for asthma patients.
Hisyam : These unwanted chemicals in the air. I suppose you could call them pollutants. Dr.H : Yes, pollutants, because they pollute the air.
Hisyam : Where do these pollutants come from?
Dr.H : Mostly from motor vehicle exhaust, factories and power stations. Hisyam : Wow, imagine that everyone. My little car also pollutes the air. Dr.H : Yes, in fact cars are the worst source of air pollution because there are so many of them.
Hisyam : ( Laughing) Look like I should use bicycle after this.
Dr.H : Yes, that’s a good idea Hisyam.
Hisyam : Ok Doctor, I’ll go straight away to buy bicycle after this. My next question, besides giving us breathing problems what are the other effects of air pollution? Dr.H : Well, people who are exposed to very polluted air can develop heart disease and lung cancer.
Hisyam : Gee, that sounds awful. What about the environment, Doctor? How does pollution affect it?
Dr.H : Well, air pollution causes acid rain.
Hisyam : Oh, so acid rain is caused by air pollution.
Dr.H : Absolutely. Air pollution also contributes to global warming and harms the ozone layer in the atmosphere by making it thinner.
Hisyam : Air pollution sounds like a serious problem.
Dr.H : Yes it certainly is.
Hisyam : Well, that’s all for today. Thanks again to our guest Dr. Hamiddey. See you all in our next topic. Taraaa.
