IV. Post-listening:
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.
