Organic
Food:Why?
Europe
is
now
the
biggest
market
for
organ-
ic
food
in
the
world,expanding
by
25
percent
a
year
over
the
past
10
years.
So
what
is
the
at-
traction
of
organic
food
for
some
people?
The
re-
ally
important
thing
is
that
organic
food
sounds
more
“natural” . Eating
organic
food
is
a
way
of
defining
oneself
to
be
natural,good,caring,dif-
ferent
from
the
junk-food-eating
masses.
Unlike
conventional
farming, the
organic
approach
means
farming
with
natural
rather
than
man-made
fertilisers
and
pesticides. Techniques
such
as
crop
rotation
improve
soil
quality
and
help
organic
farmers
compensate
for
the
absence
of
man-made
chemicals. As
a
method
of
food
production, organic
farming
is, however, ineffi-
cient
in
its
use
of
labour
and
land;there
are
se-
vere
limits
to
how
much
food
can
be
produced.
Also,the
environmental
benefits
of
not
using
ar-
tificial
fertilisers
are
tiny
compared
with
the
a-
mount
of
carbon
dioxide
emitted
by
transporting
food.
Organic
farming
is
often
claimed
to
be
safer
than
conventional
farming. Yet
studies
into
or-
ganic
farming
worldwide
continue
to
reject
this
claim. An
extensive
review
by
the
UK
Food
Standards
Agency
found
that
there
was
no
statis-
tically
significant
difference
between
organic
and
conventional
crops. Even
where
results
indi-
cated
there
was
evidence
of
a
difference,the
re-
viewers
found
no
sign
that
these
differences
would
have
any
noticeable
effect
on
health.
The
simplistic
claim
that
organic
food
is
more
nutritious
than
conventional
food
