Man has altered many of the physical features of the earth with the tools of science. He has transformed woods, lands,
and prairies into farmland. He has constructed lakes and dams to irrigate and harness hydroelectric power. By cutting
through mountains, he has almost modified the very face of the earth. However, his attempts to bring about change in the
physical environment have not always been beneficial. Today, pollution of the air and water is endangering the health of
the planet. The smoke from factories and automobiles is affecting our health. Pollution from oil factories is killing people.
The whole ecological balance of the sea is getting changed due to oil slick. Industrial and domestic wastes have choked
