25. Ch. 3: Environmental Issues
Dialogue
A: What does this graph show?

raindrops per person in the world.
26. Ch. 3: Environmental Issues
Dialogue
A: It looks like the amount of water per
person has increased / decreased over time.
B: How do you know?
27. Ch. 3: Environmental Issues
Dialogue
A: Well, in 1900 there were more than 20,000 /
25,000 cubic meters of water available per
person.
B: Yes, and by 2000 only about 5,000 / 10,000
cubic meters of water were available per person.
28. Ch. 3: Environmental Issues
Dialogue
A: Do you think the total amount of water in
the world is less now than in 1900?
B: No, the total type / amount of water in the
world is always the same.
29. Ch. 3: Environmental Issues
Dialogue
A: So why do you think the amount per
people / person had decreased?
B: The amount per person may have
decreased because the number of people
has increased.
30. Ch. 3: Environmental Issues
Dialogue
A: Oh, I see. If more people / person are
using the same amount of water, there will
be less water for each person.
B: That’s right. It is like when you and three
friends plan to share a pizza. If another
pizza / friend joins you, you will have to
divide the pizza among more people. Now
you have five people who want to eat the
pizza.
31. Ch. 3: Environmental Issues
Dialogue
A: I see what you mean. If
there were fewer / more
people in the world, more
water would be available to
each person.
B: That’s true, but there
would also be more water
available for other people if
each person uses less /
more water.
