She warns of the environmental dangers facing society, and she teaches that people must take responsibility        saving their environment.

Carson proves that a simple lyric form that has been passed down through the ages can still          (employ) today to draw attention to important truths. to teach sixth as where borrowing intended Different for warning be employed Thank you $$
