Humanity does not kill what would this world be like??

peace, love, and all countries will be sufficed to happiness and a true happy ending. there will be no fighting, people will reunite countries and boundries may be lifted. all stress, death and suicide may never happen again.
this place might be called a true heaven. perfect peace and love and true humanity.

what you might want to think about is how all of that may come to be true and how you can help to make it happen
