Given the Pope’s recent public musings, tell me this seems far-fetched for the upcoming encyclical on the environment?

“Is there a proper family size for suitable stewardship of God’s creation? We must look more deeply at this question. Of course it would be un-Christian to procreate in a way and at a rate that is destructive of the planet and our limited resources. This is anti-life and must be rejected. We must be open to life but mindful of our effect on nature. Responsible parenthood can also be responsible ecological stewardship.”
