Should We Be Concerned About the Declining Birth-Rate?

Science journalist Laura Spinney suggests that our Earth doesn't really need more human babies (https://www.theguardian.com/commentisfree/2021/jul/08/why-declining-birth-rates-are-good-news-for-life-on-earth). Spinney points out that the world human population is already around 8 billion. All these humans (to greater or lesser extents) have effects on the planet and its resources. Spinney notes that most concern for declining fertility rates emanates from politicians. They claim that new workers are needed to support their retired, aging populations. It is a truism that attempts to get people to produce fewer or more babies, generally end in failure. Perhaps the best suggestion is to encourage people to produce modest numbers of babies (if they want them) but to bring them up as environmentally aware folk? That would, of course, mean these new adults making fewer demands (in terms of where they live, what they eat and their travel arrangements) on the finite resources of the planet. This seems a bit utopian, given the marked human tendency to 'want it all'.
