what can we do for our earth

think first all,we needed more greens as usual forever.then we
are never supposed to contaminated the rivers and occeans.god
damp it,we were depending and surviving on a river water before,
but now you are hardly to find anything alive in that river.even
in canada,once in a while,certain kind of seafoods were not
allow to be catching as they were contaminated by red water.
and never mind the air pullution.sometime i really hated what
the progress have done to mother nature.but hey,nothing we
could do about it,that's life.
