Environmental
problems
are
discussed
quite
frequently
in
the
news.
A
whole
vocabulary
has
developed
to
help
us
about
the
environment
and
problems
related
to
it.
Discussing
the
environment
A.
Read
this
leaflet
about
a
new
hotel
which
is
friendly
to
the
environment.
Ecotourists
are
people
who
visit
an
area
and
do
not
harm
or
damage
the
ecosystem.
They
are
interested
in
environmental
protection.
If
you
are
this
kind
of
tourist,
you
will
love
Ecoville.
We
use
natural,
safe
energy,
from
the
sun,
solar
energy,
instead
of
digging
up
earth
to
find
fuels,
such
as
coal
and
oil.
Nothing
in
our
hotel
causes
pollution.
We
even
use
eco-friendly
washing
powder
to
wash
your
sheets.
Don’t
have
your
next
holiday
in
a
city
full
of
factories
that
create
harmful
waste.
Come
to
Ecoville,
where
you
and
Earth
will
be
safe
together.
B.
When
we
talk
about
things
that
are
bad
for
the
environment,
many
of
the
words
that
we
use
are
compound
nouns.
Use
the
compound
nouns
in
the
box
