In a sense it doesn’t really matter whether you think global population decline is a good thing or a bad thing. It is going to happen, whether we like it or not. No, it is not happening across the world YET, but it is in some countries and it is going to happen in the UK too. That’s why we need to start talking about it now! We can’t just put our heads in the sand and wait until it hits us. We need to start planning on a personal and a National and a global level. The birth rate in the UK has already collapsed, the demographic change has already started (more older people than young working people) and the population decline will inevitably follow.
The UK’s natural population will go into decline in 2025. Immigration can stop immediate depopulation, but there isn’t a baby factory in a far-off land that will continue to supply people indefinitely to prop up our society and economy. We need to come up with some other solutions, that don’t involve sacrificing reproductive rights or bumping off the elderly and disabled!
We are not breeding exponentially. Far from it! Birth rates are absolutely collapsing, worldwide. The most we can hope to do now with births is to perhaps slow the rate of decline so we can have a managed depopulation strategy and make the necessary social and economic changes, rather than suddenly dropping off a cliff.
I think the challenges of climate change, pollution, resource usage etc are well-known and discussed by many people, but a lot of people don’t appreciate that depopulation is also a massive issue that needs to be front of mind in future planning, probably because we’ve had decades of grim warnings about increasing populations.
