If I’m ignorant of some vital aspect to the whole contraception issue, I apologize in advance, but…
With a near exponentially-increasing world population (now I hear we’re supposed to hit 8-billion-or-so by 2050), eventually we’re going to hit the point where the divine mandate to “Be fruitful and multiply” will be – in my opinion – overfulfilled. One way or another, humans are going to become their own parasite, and overpopulation (yes, that it is what this thread is all about) will need to be combatted if we are to obey the other famous mandate to be good stewards of the earth. Of course, I doubt anyone’s approach to this would seriously be to stop having sex, on a account of how big it is in the functioning of the human being (as well as the whole husband-wife-union bonding deal).
So inevitably, it’s going to get to the point where banning artificial contraception would be ludicrous, so why promote such a thing now? Can doctrines only be temporary?
Or, is everyone just secretly hoping the world ends within the next fifty years so we can forget all our silly little planetary/natural resource limitations (Did you know that the world has only a 61 years supply of Copper left?).
