Listening and Speaking
I. Listen to the tape and answer and decide which statements Professor Keeling does NOT agree with.
1. We should stop depending on fossil fuels for our energy.
2. 90% of our energy comes from fossil fuels.
3. We can replace fossil fuels with
cleaner sources of energy.
4. Nuclear power is a good source of
energy.
2. Listen to Part 1 again and tick the
energy sources that are mentioned.
Complete the notes on them.
Sources of energy
Notes
Fossil fuels • Produce carbon dioxide• cheap and concentrated
form of energy
Wind power
Energy from the sun
Nuclear power
• clean
• not very practical with present technology
• does not produce carbon dioxide
• dangerous
• clean• not practical: need huge
areas of land to provide enough energy
3. Listen to Part 2 and the list three things we can do to save energy.
First we must try to find ways to use
fossil fuels that does not put carbon
dioxide into the air.
Second we must produce products
that are economical with energy.
Third we must ask people to cut
down on the energy the use.
4. Listen to part 2 again and fill in the
blanks.

Note: The USA is the largest energy user
in the world and the largest producer of
the greenhouse gas carbon dioxide.
China comes second in both of these.
Listening text
China has been going through huge
economic development, and has had as
much growth in one decade as the
industrial world experienced in nearly
a century. However, it has been at a
high cost to the environment.
FOSSIL FUELS AND OTHER
FORMS OF ENERGY
Li Bin, a university student, is
interviewing Professor Keeling on the
local student radio station about the use of
fossil fuels and other sources of energy.
Part 1
L: Professor Keeling, I've read that we
must stop using fossil fuels if we want
to reduce the amount of carbon
dioxide in the air.
K: Yes, that's right, Li Bin. However
it’s difficult.
Our modern industrial societies depend
on the energy we get from fossil fuels.
It's a very cheap and concentrated form
of energy.
L: Is it true that about 90% of
the world's energy comes from fossil
fuels?
K: Yes, that's correct. And there
is enough to last for centuries.
L: Could we replace fossil fuels with
clear sources of energy like sun or
wind power?
K: I'm afraid not. We just can’t produce
enough. You need huge areas of land to
produce enough wind energy. The
technology we have at present cannot
provide enough sun energy.
L: So what about nuclear power?
That doesn’t produce carbon dioxide.
K: True, but it’s very dangerous.
Remember the accident at
Chernobyl. People are still dying of
the radiation that was produced by
THAT disaster!
Part 2
L: So what can we do?
K: Well, there are three things. First we
must find ways of using fossil fuels that
won’t put carbon dioxide into the air.
Second, we must produce products that
are economical with energy. Third, we
must ask people to cut down on the
energy they use.
L: But that’s on a personal level. What
about factories? They don’t cut down cut
down their use of energy.
K: No, they don’t. However, that is a
problem we must work on as a global
community. That means developed and
developing countries will have to work
together.
L: But it’s not the developing countries
that put most of the carbon dioxide into
the air. The developed countries are
really the ones to blame.
K: That’s true. So we must work
together because global warming will
affect everyone. If we want the future
generations to have a good life, we must
ALL look after the planet.

MILLENNIUM KIDS
Julie, a teenager who belongs to an
organization in Australia called
Millennium Kids is visiting a class.
The teacher and students are asking
her questions about the organization.
Listening text
Part 1
T: Hello Julie. It’s so nice to see you
here. Can you tell us about
Millennium Kids?
J: Sure. It's an organization
run by kids for kids. It’s
concerned with the environment.
S1: Julie, may I ask how it started?
J: It was started by four
Western Australian kids who
organized a children's conference
on the environment in 1996. Now
we hold a conference every year.
Kids come to it from all over Australia
-- and from other countries too. It's
great fun. We discuss what we’ve done
and decide what projects we’ll do in the
following year.
S2: That sounds so interesting! What
sorts of projects do you do?
JULIE: Well, all sorts. Last year we
had a school project to help kids understand
about global warming. Actually, we
performed a play called "The Horse that
Saved the World". It taught kids not to
travel to school so often by car. It explained
why it’s so much better for the environment
if we walk, ride a bike or go by bus.
(murmurs of agreement).
Part 2
S2: Hey, I ride to school already! Is
there anything else I can do?
J: Oh, lots of things. You can encourage
your parents to buy electrical goods that
can save energy; you can wear a warm
sweater instead of turning on the heating
in cold weather; and you can
turn off electrical appliances when you are not using them.S: Thanks for that. What other projects have you done? J: We’ve planted trees and develop activities that reduce, reuse and recycle waste. This year we’re asking kids to think of ways to reduce, reuse and recycle plastic bags– they are such a problem.
S3: That sounds very interesting.T: Well, thank you, Julie. Millennium Kids certainly sounds like a good organization.J: Yes, it’s fun being a Millennium Kids. It’s also important. If we don’t care for the environment, we may not have a future. That’s a pretty good reason to do something, don’t you think?

CLEAN UP AUSTRALIA DAY
Tom is giving a talk to his class about
Clean Up Australia Day.
Part 1
Today I'm going to tell you about Clean
Up Australia Day.
Listening text
It’s one day of the year when people in
Australia get together to clean up their
local environment. It started in 1987,
when Ian Kierman was competing in a
round-the-world yacht race.
When he was shocked during the
race by the pollution he found on the
oceans. There was rubbish floating
everywhere. So when he got back to
Sydney he decided to organize a clean-
up day. He began with Sydney
Harbour.
In 1989 he got 40,000 volunteers to help
him clean it up. They collected tonnes of
old car bodies, plastics of all kinds, glass
bottles and cigarette butts.
It was so successful that Ian organized
the first Clean Up Australia Day in 1990.
This time more than 300,000 people
offered to help and it was another success.
Since then it has become a yearly event
with more and more people coming to
help. Here’s a table showing the most
common kinds of rubbish found in 2001
on Clean Up Australia Day. You can see
that the top three are cigarette butts,
glass bottles and plastic bags.
We found that some of them could be
recycled. In fact Clean Up Australia
Day works so well that we now have
Business Clean Up Day and School
Clean Up Day as well.
Part 2 After he started Clean Up Australia Day, Ian moved on to Clean Up the World Day. He got the support of the United Nations Environmental Programme, and as a result, Clean Up the World Day began in 1993. in the first year 30 million people in 80 countries were involved.
By 2001, the idea had become so popular that 40 million people from 128 countries took part. They cleaned streets, beaches, river banks and parks. I think Ian Kierman is a wonderful man. He is an inspiration to all those who have a commitment to solve world problems.
He makes them realize that people can take control of a problem themselves. They don’t have to wait for their government to act. They can also feel better knowing that they have contributed to improving the environment all round the world. (sound of students clapping)
