what

do

you

see

as

the

mainproblems

with

the

environment?D.U:

Well,

in

a

nutshell,

the

most

urgentproblem

of

all

is

the

climate.

Theworld’s

climate

seems

to

be

gettingwarmer.Int:

We’ve

seen

a

lot

of

evidence

of

that,haven’t

we?

Hotter

summers,warmer

winters,

that

kind

of

thing.D.U:

Yes,

we

have.

Also,

scientists

havefound

that

the

ice

at

the

Poles

isbeginning

tomelt.Int:We

have

heard

that

too.

Is

that

reallyhappening?D.U:

Yes,

I’m

afraid

it

is.

And

at

somethingin

the

future,

the

ice

may

meltcompletely.

Then

it’s

possible

that

thesea

could

rise

and

coastal

cities

likeNew

York

and

Shanghai

coulddisappear

under

water.Join:

It

sounds

very

frightening.D.U:

I

couldn’t

agree

with

you

more.

It’sscary!Int:Can

you

explain

why

the

climate’sgettingwarmer?D.U:

Well,

I’ll

do

my

best!

It’s

pollutionthat’s

the

problem.Gases

from

cars

enter

theatmosphereand

stop

the

sun’s

heat

from

leavingthe

atmosphere.

And

factories

giveoutchemicals

that

do

the

same

thing.

So

asa

result,

the

climate’s

getting

warmer.Int:

From

what

I

understand,

carbondioxide

from

cars

is

a

major

problem.D.U:

You

are

absolutely

right.

Carbondioxide

is

the

gas

that

does

mostdamage

to

the

atmosphere.

But

wehave

a

problem

with

trees

too.

You

see,trees

give

out

oxygen

and

take

incarbon

dioxide.

So

they’re

very

usefulbecause

they

use

upthecarbondioxide.Int:I

know

what

you’re

going

tosay.We’re

cutting

down

all

the

trees.D.U:

Yes,

we

cut

them

down

becauseweneed

the

land

and

because

we

use

thewood

for

paper

and

furniture.

Thatleaves

more

carbon

dioxide

in

theatmosphere.Int:

It’s

a

terrible

situation.D.U:

Yes,

and

another

problem

is

all

thegarbage

that

we

produce.

We

burn

a

lotof

garbage,and

once

again,thegasespollute

the

atmosphere.

The

situationcouldn’t

beworse,

really.Int:

We

should

recycle

garbage,

not

burn

it.D.U:

Of

course

we

should.Int:It’s

strange,

we

know

all

this,

and

yetwe

do

nothing

but

talk

about

it.

I

can’thelp

but

feel

veryconcerned.D.U:

Yes,

well,

it

is

worrying.
