We need to embrace and adapt to a decrease in population because the explosion that has happened is unsustainable and so are current global population levels. That's the best, if not only, way to both get rid of poverty globally and to preserve the climate and environment.
This does not mean that population should or will collapse to extra low levels...
Its just math showing the trend and it's not worthless as it should give you something to think about.
>> We need to embrace and adapt to a decrease in population
Of course, but it will be painful.
>> That's the best, if not only, way to both get rid of poverty globally and to preserve the climate and environment.
That simple math, which you deem worthless also tells you this is impossible. There will be a small number of young active people having to support a big group of elderly. They will not have the time to solve world problems. In fact a lot of knowledge will be lost as economy will contract and there will be less people available for specialization.
We need to embrace this and use existing and new technologies to cope. We have AI, automation, robots progressing fast, this is exactly what we need in addition to investing in education.
The alternative is to keep pushing for an ever growing population and to end up in Soylent Green / Blade Runner.
Based on history it hasn't happened. How do you know it's going to?
>>The alternative is to keep pushing for an ever growing population and to end up in Soylent Green / Blade Runner.
That is absolutely not the only alternative. One would be to have a stable population at the current size. Another on would be decreasing population slowly and not as drastically as it will happen in Korea. A third one would be growing it slowly. The fourth one would be oscillating around the current size, etc.
"The second derivative of population will remain constant for the next 100 years" is just as silly today as it was in 1925.
