Good morning everyone. Let me introduce myself. My name is Lam, studying at A High School. Today, I am very glad to tell you about my topic “Air pollution”. My presentation is divided into three main parts including (1) Causes of air pollution, (2) Impacts, and (3) Suggestion of solutions. It takes me about 15 minutes to cover all of the main parts of my talk. If you have any questions, I will be happy to answer them after my presentation.

Air pollution is becoming more and more serious

First of all, I would like to talk about the Causes of air pollution. The first cause I want to mention is gas emissions from factories and vehicles. As the gases from factories are not treated, they are very harmful to not only the air but also the environment. One of the substances contributing to the air pollution found in these gas is carbon dioxide (CO2) – one is also included in the gas emissions from vehicles. Additionally, nowadays, more and more plants and vehicles are appearing, contributing to the more serious of air pollution. The more gases discharged into the air, the more polluted the air is. And this brings a number of bad effects on both the environment and humans.

Now, I will continue with the second part about its impacts. Firstly, the polluted air certainly affects the environment. The air pollution means that the CO2 in the air is high, and this gas will cause the greenhouse effect. This phenomenon will result in global warming and this is very bad for the environment. Also, the ecosystem is influenced because, in places where the CO2 is more than Oxide, living things are hard to survive. They can die or become extinction. Another impact is harming human life. The polluted air damages people’s health because it causes respiratory diseases. Besides, it might have negative influences on daily life. As the air is polluted seriously, people will prefer staying at home rather than going out to avoid diseases, interrupting their lives. Moreover, pollution also costs the government money to handle problems. Every year, the government needs to spend a large amount of money to deal with air pollution to better society. If it is not prevented as soon as possible, the amount will increase gradually.

Trees are useful assistants to reduce air pollution

Finally, I want to talk about the suggestion for solutions to solve the air pollution problem. Objectively speaking, it would be better if the government have suitable strategies such as encouraging people not to cut down trees without its permission and to use public transport to reduce the number of the vehicles as well as implementing appropriate strict laws to require plants to treat their exhausted gas before they are discharged into the air. Subjectively speaking, we should be aware of air protection. We should use green energy and not cut down trees without permission from the government and travel by walk or by bike. Let’s protect our air for the next generation together.

This brings me to the end of my presentation. To sum up, I would like to mention what I have said so far. First, I talk about the causes of air pollution. Next, its effects are mentioned, and finally, I suggest some solutions to protect our air. Thanks for listening. Now, it’s time for Q and A.
