We don't need to encourage it, birth control and capitalism have already produced a depopulation trend in all developed countries. It's not a good thing.

It's not a good thing because???? I'll accept a well reasoned argument, but you've not presented any yet in this discussion and engaged in your own naturalistic fallacies. If you're using the reason that "Wanting to breed is natural" then surmise that you've never been involved in animal husbandry before. Nor have you studied mammal populations between species, especially those that have boom and bust cycles.

The article outlines plenty of good reasons, that's why we're discussing it. Most depopulation scenarios are nightmares (wars, famines, genocides), and even the good ones are very, very unpleasant (disproportionate resources must be directed towards caring for the aging population, leaving little labour for maintenance of existing infrastructure, let alone development).
