Unit 4 Acid Rain!
M: I hate this rain. It’s causing the traf ic to back up
for miles!
W: Wel , I hate this traf ic, because it’s helping turn
this rain into acid rain. M: I heard that acid rain has real y bad ef ects. Doesn’t it cause cancer and brain damage, and
even Alzheimer’s disease?
W: It definitely can, but the major thing it does is cause breathing problems. The acid in the rain
comes from smoke and gases that are given of
by cars and factories. It’s like riding your bike behind a bus that’s showering you with its exhaust fumes. M: Oh, I was reading something about that the other day. It said there’s too much sulfur in the
air and that it’s kil ing thousands of people every
year. W: Yes. Sulfur is the major element in factory and
car exhaust. It combines with oxygen and nitrogen
in the air to become the acid in acid rain. This
stuf doesn’t just kil us, you know. It also kil s
trees and lakes and animals. The acid soaks into
the plants and animals, so that anyone who eats
the plants and animals is also eating the acid. M: This sounds ter ible! What can people do to
stop acid rain?
W: One simple thing they could do is to use less energy. Another way to stop acid rain is to drive
less, or at least carpool. Imagine if every car on
this road had four people in it right now. There would be fewer cars and a lot less acid rain.
