What are we doing?

Does this world truly exsist?
Immediately open to all of us born into it
but when we were born we did not realise
that our actions soon would darken the skies
that our human inventions would ruin the earth
even cause some deffective births
why did we put this early doom upon us all?
when we die everyone should know it was our fault
from our insane horrible habits
to our stupid drug addicts
we should have known it would kill as all
but we didnt think, didnt care
about how we were polluting the air
we need to stop and quit these horrid habits and start anew and refreshed
with only ourselves in the way we could join in the fight
the fight to make this world right
