C. READING. (2,5pts)

Land pollution is when humans introduce harmful objects, chemicals or
substances, directly or indirectly, into the soil in a way that causes harm to other
living beings, destroys soil or water ecosystems. It can be caused by agricultural
sources, industrial sources, sewage treatment, and deforestation.

A. Farmers often use highly toxic fertilizers and pesticides to get rid of insects,
fungi and bacteria in their crops. However with the overuse of these chemicals,
they often result in contamination and poisoning of soil.

B. Industrial activity is also one of the biggest contributors to this problem in the
last century, especially since the amount of mining and manufacturing has
increased. Most industries are dependent on extracting minerals from the Earth.
C. Another reason is the sewage treatment. Household or municipal waste such as
glass, metal, cloth, and plastic is collected and gets dumped in a landfill or burned
to generate electricity. Both end up polluting the environment.

D. Deforestation is carried out in order to create dry lands. This is a major concern.
When trees are cut, the earth’s surface is left unprotected from rain and the sun’s
intense heat. Accordingly, the unfavorable conditions result in soil erosion, land
degradation, and desertification.

E. The effects of land pollution are very hazardous and can lead to the loss of
ecosystems. When land is polluted, it directly or indirectly affects climate patterns,
rainfall or temperature.

F. Land pollution has been found as one of the leading causes for birth defects.
Pregnant women living in unhealthy and dirty environments can incur breathing
problems and a number of diseases, which may affect the health of the baby as
well.

So what should we do to reduce land pollution?
I. Match the words with their definitions.

Landfill Plastic Mining Deforestation Fertilizers
1. ………= substances added to soil to make plants grow more successfully

2.………. = the process of getting coal and other minerals

3.………..……. = an area of land where large amounts of waste material are
buried

4.……… = the act of cutting down or burning the trees in an area
II. Read the text and decide in which paragraph each detail below is 
mentioned. Write A, B, C, D, E or F in the blank.
