World population is now passing 8 billion. Growth is said to be slowing, but still high in places like Egypt; happens to be where COP27 was held.
Population growth and climate change are seen as causes for larger migrations of people in future years.
I saw one article saying this leads to political pushback in shortrun, but still could be a benefit to the economies and talent pools of northern countries in the long run.
I'd say we would have to fix our housing shortage and traffic problems first. USA would need to plan for more density and less dependency on the automobile to accommodate a huge flow of immigrants.
The flow exacerbated by bigoted anti human rights and anti LGBTA policies in much of the non western nations. Nations that still oppress alternatives to procreation as the only lifestyle choice.
I read that world population growth is slowing, but still high in a few nations like Egypt, Nigeria, Ethiopia and Congo.
Egypt, site of recent Climate Conference, has little land area and it's water supply, from Nile River, is in question. Growing needs up river; such as in Ethiopia, divert water.
Ethiopia is in civil war as well. There's likely to be a lot of suffering in non western nations due to population growth, bad governance and aspirations for more prosperous lives.
The issue of western nations paying reparations was a sticking point in the conference and it seems unlikely to happen. The west is struggling with it's own green transition and housing shortages.
Hopefully we can and will help the rest of the world adopt greener technology; if we adopt it ourselves which is still in question.
Maybe the rest of the world can teach us to live more simply, but that's still in question also.
I think the road to a brighter future will require big changes in thinking both in the traditional values of non western nations as well as the way space and resources are used in prosperous western nations.
Here in USA we will have to change our ways and plan for more density.
If changes happen in both the west and the non west, we can still welcome new generations and have a future.
