Task 3 Listen and list all the resources you hear Then tick which resources is renewable and which is nonrenewable.

Sources of energy Renewable Nonrenewable

Should we use a lot of lights in our house at night? Why?

Because that is very waste of energy

Should we mine as much coal as we like? Why (or why not)?

Because it takes millions of years to make coal.

Energy is very important to our life We should

use them as economically as possible

TAPE SCRIPT

The natural environment includes all natural resources

that are necessary for life: the air, the oceans, the sun and the land Because they are vital for life, these resources

must be protected from pollution and conserved Ecologists study their importance and how to use them carefully

According to ecologists, resources are divided into 2

groups: renewable and non-renewable When a resource can be replaced quickly, it is called renewable If it cannot

be replaced quickly and easily, it is non renewable For

example grass for animals is a renewable resource When cows eat the grass , the resource is used If the soil is

fertilized and protected, more grass will grow Coal,

however, is nonrenewable because it takes millions of years

to make coal All fossil fuels are nonrenewable resources

TAPE SCRIPT

Solar energy, air, and water are renewable resources because there is an unlimited supply However, this definition may be

changed if people are not careful with these resources The

amount of solar energy that reaches the earth depends on the atmosphere If the atmosphere is polluted, the solar energy that reaches the earth may be dangerous If life is going to continue, the air must contain the correct amount of the air must contain the correct amount of nitrogen (N), oxygen (O), Carbon dioxide (CO2), and other gases If humans continue to pollute the air , it will not contain the correct amount of these gases.
