Dying weeds us out. What if no one ever died? HOw many trillions or bazillions would there be? WOULD BIRTH CONTROL BE MANDATORY?

If no one ever died, this planet would have stopped being able to support them thousands of years ago.  Resources would long have been exhausted, people would be living on every inch of the globe - like sardines in a can, progression would have stopped as there would be no need for it as all the "great" minds of yore would still be here.  Global wars would break out every other day (we want this, do things our way, etc.), and since no one could die, fighters would literally be swimming in blood on every battlefield

Of course, it's possible that people would have outlawed reproduction when they say that the world was becoming crowded.  They may have even mutilated bodies to make sure no one could ever reproduce.  But there's always those who won't conform and will do what they want no matter what (rights).
