Steve, I must have hit a sensitive point! You are worrying about a thing which is WAAAAY, WAAAY out of your reach. And mine as well.
Is it any wonder that people would want to be in a cooler climate like Italy when population explosion has caused climate change and over heated areas south of you!
I strongly doubt that the population explosion in Africa has caused a climate change. Maybe the climate change is making it hard for natives to survive in some areas, the Sahel around the Sahara desert.
Nevertheless, the truth is that in Europe there is negative growth. In contrast, the Africans who give birth to so many children are trying to immigrate into Europe, looking for better conditions, sometimes believing everything will be easy. They will be given free money and easy jobs.
In America, if the following is true:
How is the population in the US changing?
How has the US population changed over the years? The US population increased 12 out of the 12 years between year 2010 and year 2022. Its largest annual population increase was 1% between 2019 and 2020. Between 2010 and 2022, the country grew by an average of 0.6% per year.
Then your concern would be at least in part justified, people are increasing, not so much, but how many of them are immigrants? And if they are not, why to add immigrants to an already growing population? And why not to populate rural areas instead of towns? In America, there is so much room for everyone.
Mr Trump and Mr. Vance are apparently doing the right thing promising to stop immigration. Their appeal to growth increase will go unheeded, unless they are able to provide the right economical support.
I'm afraid that, whoever will be elected, the population will increase evermore, and if the newly elected will allow immigrants, it will be a huge wave of poor people, with a substantial amount of criminals and psychopaths. Good luck.
