What
happens
____________________
we
do
not
take
care
of
the
____________________
?
These
are
all
____________________
on
a
large
scale
.
Humans
are
not
very
good
at
dealing
with
large
-
scale
problems
because
large
-
scale
problem
solving
involves
the
co
-
operation
of
____________________
with
each
other
.
In
fact
,
humans
are
not
very
good
at
____________________
with
each
other
without
trying
to
make
a
profit
for
themselves
.
In
small
communities
people
tend
to
help
each
other
.
In
big
cities
,
every
person
tends
to
think
of
himself
,
and
whoever
can
.
The
hole
in
the
____________________
____________________
was
an
important
issue
,
but
the
required
human
cooperation
was
to
ban
____________________
and
other
substances
that
depleted
the
ozone
layer
.
The
industries
that
made
these
ozone
-
depleting
substances
were
not
dependent
on
____________________
for
their
benefits
and
were
able
to
make
other
substances
that
worked
the
same
but
did
not
harm
the
ozone
layer
.
In
these
circumstances
cooperation
between
nations
was
possible
.
.
The
companies
that
offer
these
____________________
do
not
want
to
lose
the
benefits
of
providing
them
,
just
as
the
chemical
companies
did
not
want
to
lose
their
profits
from
the
____________________
of
substances
that
deplete
the
ozone
layer
.
There
are
,
however
,
many
more
vested
interests
in
these
____________________
that
create
____________________
change
.
.
.
than
those
in
the
companies
that
created
ozone
-
depleting
substances
.
And
this
is
not
good
at
all
.
Instead
of
____________________
for
the
environment
,
we
only
care
about
it
,
instead
of
protecting
the
environment
,
we
are
only
thinking
about
how
to
____________________
it
.
The
problem
is
that
if
we
do
not
care
about
the
environment
immediately
,
the
environment
will
not
take
care
of
us
.
As
____________________
of
the
world
,
each
of
us
is
responsible
for
the
health
of
our
planet
.
Our
decisions
and
our
actions
contribute
to
the
good
or
deterioration
of
the
environment
.
However
,
it
is
our
land
,
the
only
one
we
have
.

we

Who

natural
resources

Who
will

safe

to

We
have
to
do
it
,
and
participate
in
making
our

a
safer

less
