Ex2. Listen a small talk about “Pollution” and decide if the following sentences are True or False.

Question 1. People care about the environment but  they pollute the air to make lots of money.  

Question 2. We are all much healthier because of companies that pollute the air or our rivers.

Question 3. Pollution affects us all.

Question 4. Barack Obama is going to do his best to help the Earth.

Question 5. If pollution gets any worse, we’ll be in seriously little trouble.

The environment is the natural world in which people, animals and plants live. The natural environment has been seriously affected and (1)

by human activities through many decades. For instance, the burning of fossil fuels by factories and motor vehicles has led to air pollution and (2)

acid rains, greenhouse effect and health problems.

We should do something immediately to protect our environment. For instance, we should control the burning of fossil fuels and encourage forestation to replace (3)

. In addition, there should be appropriate places to dump (4)

and chemicals to reduce the rate of water pollution, a threat to human health and a danger to aquatic animals.

To minimize the rate of environmental degradation and to raise awareness of its threats, the (5)

of the environment should be included in education and mass media. People should make every effort to preserve the environment for the next generation.

To learn how to talk about these

, we will discuss threats to the

environment, their causes and possible solutions. Probably the biggest

to the environment is global warming. Let’s look at the causes 

and what we can do about it. Burning fossil fuels, such as coal, oil and gas,

carbon dioxide into the atmosphere. These gases then get

in the atmosphere. This layer of gases trap in heat radiating 

up from the Earth. This causes the planet to get hotter. We call this The Greenhouse Effect, because it is similar to how a greenhouse works by 

trapping the heat from the sun. So the Earth is getting

. What can

we do to solve this problem? We can

the amount of 

greenhouse gases that we put into the atmosphere. There are many things we can do to help. Here are a couple. We should use energy saving light 

bulbs. And we can drive more 

cars.

So burning fossil fuels leads to global warming, but what are the negative

of higher temperatures and what should we do to help the

environment? The ice caps are

. As a result, sea levels are rising.

We should use

energy. Deserts are growing. We should

plant more trees.
