Whilst I agree with your sentiments, it's a dangerous road to travel down. It is very easy to conceive(note the rise in world population in the last 100yrs.
The solution would be compulsory contraception, mass or forced abortion...or mass or forced sterilization.

Every single sector of society(some religious, some not) would fight against some or all of these.
The only way to halt this is through greater economic independence and education(particularly for women - the more educated a woman the less children she has).
