Unit 7-Pollution
1. Work in pairs. One of you looks at picture A, and the other looks at picture B on page 15. Ask each other questions to find out the differences between your pictures.
A
- The ducks are white.
- They’re going to the lake.
- There aren’t any factories near the lake
- The lake water is clean.
B
-The ducks are black.
- They’re going from the lake.
- There are some factories near the lake
- The lake water is dirty.
2. Mi and Nick have decided to give a presentaion on water pollution to the class. Read what they have prepared and answer the quest
Water pollution is the contamination of bodies of water such as lakes, rivers, oceans, and groundwater (the water beneath the Earth’s surface). It is one of the most serious types of pollution.
Water pollution can have many different causes. Factories dump industrial waste into lakes and rivers. Sewage from households is another cause. Farms using pesticides to kill insects and herbicides to kill weeds can also lead to water pollution. These factors cause ‘point source’ pollution while pollutants from storm water and the atmosphere result in ‘non-point source’ pollution.
Water pollution can have dramatic effects. In many poor nations, there are frequent outbreaks of cholera and other diseases because of people drinking untreated water. Humans can even die if they drink contaminated water. Polluted water also causes the death of aquatic animals such as fish, crabs, or birds. Other animals eat these dead animals and may also get sick. In addition, herbicides in water can kill aquatic plants and cause further damage to the environment.
So what should we do to reduce water pollution?
1
What does the second paragraph tell you about?
2
What does the third paragraph tell you about?
3
What is groundwater?
4
What are point source pollutants?
5
What are non-point source pollutants?
6
Why do people use pesticides?
1. What does the second paragraph tell you about?
The second paragraph tells us about the causes of water pollution.
2. What does the third paragraph tell you about?
The third paragraph tells us about the effects of water pollution.
3. What is groundwater?
It’s the water beneath the Earth’s surface.
4. What are point source pollutants?
They are industrial waste, sewage, pesticides and herbicides.
5. What are non-point source pollutants?
They are pollutants from storm water and the atmosphere.
6. Why do people use pesticides?
They use herbicides to kill weeds.
3. Read the text again and complete the notes about the effects of water pollution. Fill each blank with no more than three words.
1. If the drinking water is untreated, an outbreak of                     may happen.
2. People drinking contaminated water may                   .
3. Fish, crabs or birds, may also die because of                   .
4. Other animals may become ill if they eat the                    animals.
5. Herbicides kill both weeds and                   .
4. Work in groups and discuss the solutions to water pollution. Make notes of your answer.
1
Give heavy fines to companies that are found doing this.
2
Educate companies about the environment.
3
Give tax breaks to companies that find “clean” ways to dispose of their waste.
5. Now complete the diagram of water pollution. Use the information from the text for the causes and effects and your group`s ideas for the solutions.
6. Make a presentation about water pollution.
Water pollution means one or more substances have built up in water to such an extent that they cause problems for animals or people. There are also twodifferent ways in which pollution can occur. If pollution comes from a single location, such as industrial waste into lakes and rivers, sewage from households, pesticides and herbicides, it is known as point-source pollution. While pollutants from storm water and the atmosphere result in "non-point source" pollution. Water pollution can outbreak of cholera and other diseases, even die in human. It also causes the death of aquatic animals and plants and further damage to the environment. Dealing with water pollution is something that everyone needs to do. With the laws, governments have very strict laws that help minimize water pollution. Making people aware of the problem is the first step to solving it.
