The
world
has
limited
resources
and
a
growing
population
.
By
the
____________________
of
this
century
there
could
be
three
billion
extra
mouths
to
____________________
.
So
wasting
food
,
this
new
report
says
,
is
a
tragedy
that
____________________
not
continue
.
The
study
says
changing
the
way
consumers
in
the
____________________
world
reject
less
-
than
-
perfect
-
looking
vegetables
in
the
shops
,
and
____________________
large
quantities
of
meat
-
which
requires
a
lot
of
resources
to
____________________
to
market
-
could
have
an
impact
.
But
the
engineers
who
wrote
____________________
report
also
recommend
better
use
of
scarce
land
and
water
around
____________________
whole
world
.
They
say
that
putting
more
land
to
agriculture
will

difficult
without
damaging
the
environment
,
so
improving
the
efficiency
of
farming
____________________
vital
.
The
report
says
better
irrigation
is
the
key
here
,
because
____________________
used
in
agriculture
is
often
sourced
badly
:
from
aquifers
which
are
____________________
managed
.
In
some
cases
,
the
engineers
say
,
governments
and
aid
agencies
____________________
exacerbated
this
problem
by
sinking
boreholes
in
the
wrong
places
.
The
____________________
also
says
that
irrigating
crops
through
spraying
or
flooding
fields
is
____________________
because
so
much
of
the
water
evaporates
.
It
says
that
drip

trickle
methods
of
irrigation
,
while
more
expensive
to
install
,
can
be
____________________
much
as
a
third
more
efficient
.
