Host:
Good
morning,
listeners.
Today
is
World
Food
Day,
and
David
Bond
from
the
UNS
FAO
is
here
to
talk
to
us
about
world
hunger.
Welcome,
David!
Please
explain
what
the
FAO
is
and
what
its
aims
are.
David:
Good
morning.
For
those
who
don’t
know,
FAO
stands
for
Food
and
Agriculture
Organisation.
And
our
aim
is
simple—to
eliminate
world
hunger,
which,
according
to
our
latest
figures,
stands
at
around
11%
of
the
world's
population
Host:
So
I
guess
things
like
droughts,
floods,
and
climate
change
are
all
major
factors
in
this.
David:
Yes,
that’s
right,
they
can
all
seriously
affect
crop
production.
And
another
factor
is
poverty.
There
is
strong
evidence
to
suggest
that
many
people
just
can’t
afford
to
eat
well.
And
it's
not
just
about
having
enough
food
to
eat;
people
need
to
eat
enough
nutritious
food,
which
often
they
cannot
afford
or
do
not
have
access
to.
The
FAO
believes
everyone
should
have
the
right
to
healthy
food.
Host:
And
what
about
war?
I’ve
seen
many
researchers
say
that
it
directly
leads
to
mass
hunger.
David:
Absolutely
true.
Our
research
indicates
that
wars
can
heavily
affect
food
production
and
transportation,
meaning
that
millions
of
people
have
to
go
hungry
Host:
So
what
can
we
do
to
alleviate
world
hunger?
David:
Well,
the
UN
is
making
efforts
to
reduce
climate
change,
and
the
FAO
runs
a
project
called
Climate-smart
Agriculture,
which
helps
countries
to
develop
sustainable
agriculture.
However
every
country
needs
to
focus
on
making
new
achievements
in
agriculture,
too,
which
can
often
benefit
the
whole
world.
Like
China,
for
example,
whose
development
of
hybrid
rice
has
greatly
increased
rice
production
in
many
other
countries.
And,
of
course,
global
conflict
must
be
eliminated.
And
don’t
forget
that
we
as
individuals
can
also
make
a
difference:
buy
food
that
supports
the
environment,
and
never
waste
food.
Host:
David
Bond,

you
very

Sample
Dialogue
A:
So
what
shall
we
do
for
World
Food
Day?
B:
My
view
is
that
we
should
have
a
World
Food
Day
Sunday
Dinner.
C:
What
is
that?
B:
Well,
everyone
buys
tickets
to
eat
a
dinner,
and
the
price
of
the
tickets
is
the
same.
But
when
they
buy
the
tickets…
…they
have
to
draw
their
tickets
at
random.
Some
people
get
tickets
to
eat
like
a
poor
person—just
a
small
bowl
of
rice.
Others
get
tickets
to
eat
like
an
average
person—
noodles
with
meat,
perhaps.
Finally,
others
get
tickets
to
eat
like
a
king—roast
duck
and
all
sorts
of
sweets.
A:
What’s
the
purpose
of
such
a
meal?
B:
In
real
life,
how
well
a
person
eats
is
really
just
a
matter
of
luck.
If
you
are
born
in
a
wealthy
country,
you
probably
eat
well
and
might
even
be
fat!
But
if
you
are
born
in
a
poor
country,
you
might
just
starve!
A:
I
believe
that
you
might
be
onto
something.
But
who’s
going
to
cook
the
food?

Yuan

Read
the
statistics
below.
According
to
the
World
Health
Organization
(WHO).
●The
world
produces
enough
food
for
everyone.
●More
than
800
million
people
go
to
bed
hungry
every
day.
Did
you
know
these
facts
before?
What
problem
do
they
show?
Rice
is
the
main
food
in
all
East
Asian
and
Southeast
Asian
countries.
What
do
you
think
would
happen
if
tomorrow
there
were
suddenly
no
rice
to
eat?
Every
year
15
million
children
die
of
hunger.
About
183
million
children
weigh
less
than
they
should
for
their
age.
Do
something
to
help
end
hunger
in
the
world!!!
The
only
way
to
solve
the
food
shortage
problem
is
to
increase
the
yield
of
the
graincrop
per
land
area
through
the
advancement
of
science
and

Pre-reading

that

and
his

After
graduating
in
1953,
he
worked
as
a
researcher.
Yuan
Longping
realised
that
larger
fields
were
not
the
solution.
Instead,
farmers
needed
to
boost
yields
in
the
fields
they
had.
How
this,
could
be
done
was
a
challenging
question
at
the
time.
Yuan
was
convinced
that
the
answer
could
be
found
in
the
creation
of
hybrid
rice.
A
hybrid
is
a
cross
between
two
or
more
varieties
of
a
species.
One
characteristic
of
hybrids
is
that
they
usually
attain
a
higher
yield
than
conventional
crops.
However,
whether
it
was
possible
to
develop
a
hybrid
of
self-pollinating
plants
such
as
rice
was
a
matter
of
great
debate.
The
common
assumption
then
was
that
it
could
not
be
done.
Through
intense
effort,
Yuan
overcame
enormous
technical
difficulties
to
develop
the
first
hybrid
rice
that
could
be
used
for
farming
in
1974.
This
hybrid
enabled
farmers
to
expand
their
output
greatly.

What

most
about

his
ongoing
ability
to
fulfill
his
dreams.
Long

envisioned
rice
plants
as
tall
as

with
each
ear
of
rice
as
big
as
a
broom,
and
each
grain
of
rice
as
huge
as
a
peanut.
He
succeeded
in
producing
a
kind
of
rice
that
could
feed
more
people
at
home
and
abroad.
His
latest
vision
for
“seawater
rice”
has
also
become
a
reality,
and
potentially
opened
up
nearly
one
million
square
kilometres
of
salty
land
in
China
for
rice
production.
Despite

advanced
years,
Yuan
Longping

Organic
farmers
also
use
many
other
methods
to
produce
rich
soil.
They
often
change
the
kind
of
crop
grown
in
each
field
every
year.
For
instance,
they
may
grow
corn
or
wheat
in
a
field
one
year,
and
then
grow
beans
there
the
next.
Why
different
crops
are
grown
is
because
they
put
important
minerals
back
into
the
ground,
making
it
ready
again
for
the
next
batch
of
crops.
Organic
farmers
also
plant
diverse
crops
that
use
different
depths
of
soil
to
help
keep
it
rich.
For
example,
peanuts
grow
on
the
ground's
surface,
but
many
other
vegetables
put
down
deep
roots.
The
goal
of
using
different
organic
farming
methods
is
to
grow
good
food
while
avoiding
damage
to
the
environment
or
to
people's
health.
