One possible version
     There is no doubt that a green campus plays a decisive role in the growth of every student, physically
and mentally.
     A green campus not only refers to the eco-friendly environment where we study but also the place we
learn to live in harmony with our peers as well as nature.
     In my view, laying down regulations and rules on campus should be the first step we take to ensure
appropriate conducts among us students. For example, we are not allowed to leave tap dripping after use.
Plus, it is of great significance to enhance every student's awareness of creating a green campus. For
example, posters can be put up around the campus to remind us to walk instead of taking lifts or to
encourage honesty and mutual respect among us.
     We believc that, if we make joint efforts, a green campus will be achieved in the near future.
