Last
Friday，a
discussion
on
the
theme
“What
will
the
future
be
like？”
was
held
among
students
in
Senior
Three
in
the
lecture
hall
of
our
school.Some
students
are
quite
optimistic，believing
that
in
the
future，with
the
development
of
science
and
technology，transportation
will
be
more
convenient
and
human
beings，who
enjoy
higher
quality
of
life，will
live
much
longer.However，other
students，who
are
a
little
pessimistic，hold
that
in
the
future
as
natural
resources
further
decrease，
farmland
will
become
less.What’s
worse，pollution
will
be
more
serious
and
more
traffic
accidents
will
happen.After
the
discussion，we
realize
we
should
take
immediate
measures
to
protect
natural
resources
and
reduce
environmental
pollution.
