It's tremendous news. The carrying capacity of the Earth is closed to 1 billion people (we're at ~7 billion, and on track to hit ~10 billion by the end of the century due to population momentum). Target total fertility rate should be as close to 1 as possible.
This is a subject near and dear to my heart as a systems observation wonk, and have done a tremendous amount of research on the subject.
I recommend these two books to those interested:
Shrinking-population Economics: Lessons From Japan by Akihiko Matsutani
Countdown: Our Last, Best Hope for a Future on Earth? by Alan Weisman
