Activity 4

  1. Listen to a recording of the following speech and answer the questions orally.

Good morning, everyone and thank you for coming to listen to me. All of us would like to breathe in fresh air and to drink clean water, wouldn’t we? Well, it is becoming more and more difficult. This is because we have polluted our environment. Pollution means the presence of unwanted and harmful substances in the atmosphere.

Our earth is the only planet in the universe which has an environment suitable for life. However, pollution is making the earth a terrible place not only for people, but also for other creatures.

Our industries are one major cause of pollution. They emit toxic gases and chemicals which fall back on earth as acid rain. Even the vehicles on our roads produce a lot of carbon monoxide. If you live near a major highway, the air you breathe is likely to be polluted. Sometimes dangerous industrial waste is drained into rivers and lakes, making our drinking water unsafe. Pollution may cause diseases like cancer. When people fall sick, they are unable to work and they become poor.

All of us must begin to conserve our environment. If we join hands, we can plant trees, clean our rivers, stop all forms of pollution and make our world a better place. Air pollution, water pollution and noise pollution are all dangerous. Say “No” to pollution. Say “Yes” to a safe clean environment. After all, cleanliness is next to godliness.

Thank you.
