We have cancer because we are a cancer to this world.  If we were in harmony with the planet, with ourselves, we would be the cure.  Our inter actions with the earth, and our societies is detrimental to the species and the fragile ecosystem which allows us the breath.  We must use our intelligence.  We are a new species to this planet.  We are still learning where we are and how to behave.  We recently rethought slavery.  Rights of women.  Such significant things.  There is another we must realize, we are equals.  Each of us, mother father daughter and son.  An equal.  No borders.  Nothing separates us.  We are family bread from each other.  We are children of earth in the care of our species.  And if this young species is to mature again it should see the benefit of uniting its children for the planetary peace resulting from peaceful beings cooperating and volunteering to do what needs being done. Be that peaceful being so world peace could exist automatically.  So grow up.  The survival of this species depends on your reason.
