In a sign that I have fallen behind on my reading, I have yet another NewScientist (31 August 2019) reference:
A Chinese government policy allowing all couples to have two children led to an additional 5.4 million births in the first 18 months after it took effect.
China’s universal two-child policy, announced in October 2015, was designed to boost the country’s stagnating population growth. …
Birth rates declined to a low of 1.49 births per woman in 1999. Driven by concerns about an ageing population and shrinking workforce, from November 2013, a selective two-child policy was introduced: couples were allowed to have a second child if either parent was an only child.
Putting more pressure on the environment, the cities, and, in general, human civilization. This strikes me as the malevolent spreading of a morality appropriate to small groups to the biggest group around, and watching it eat everything in sight.
