One other thing to keep in mind as well: much of our current population explosion isn't even due to massive birth rates. It's the result of much lower infant mortality. If we were to still have the infant mortality rates we had in the beginnings of the 20th century with current global birth rates, i'd even speculate that population would already be declining. Since said birth rates continue to decline, the trend looks good globally.
