保护环境，人人有责Everyoneshouldplayapartinenvironmentalprotection.Paragraph1Many

have

heard

of

shark’s

fin

soup.This

famous

and

expensive

dish

is

especially

popular

in

southern

China.

But

do

you

realize

that

you’re

killing

a

whole

shark

each

time

youenjoy

a

bowl

of

shark’s

fin

soup?

Paragraph2When

people

catch

sharks,

they

cut

off

their

fins

and

throw

the

shark

back

into

the

ocean.

Without

a

fin,

a

shark

can

no

longer

swim

and

slowly

dies.

This

method

is

not

only

cruel,

but

also

harmful

to

the

environment.

Sharks

are

at

thetop

of

the

food

chain

in

the

ocean’s

ecosystem.

If

their

numbers

drop

too

low,

it

will

bring

danger

to

all

ocean

life.

Many

believe

that

sharks

can

never

be

endangered

because

they

are

the

strongest

in

their

food

chain.

But

in

fact,

around

70

million

sharks

are

caught

and

traded

in

this

industry

every

year.

The

numbers

of

some

kinds

of

sharks

have

fallen

by

over

90

percent

in

the

last

20

to

30

years.
