I was reading an article about how our government needs to change its fiscal policies to account for an aging population. In the comments on the story, someone claimed that there is actually a population implosion, a negative growth rate world-wide, and that population overgrowth is a myth.
I was unable to find anything in a quick Google search that looked reliable to support this idea. (one page, the article was used to support anti-abortion laws - like forcing women to bear children is the solution...IF there is even a problem).
Is there any science supporting this?
There isn't a negative growth rate world-wide. Population overgrowth is not a myth. In fact, our species is becoming verminous and is chewing up the planet.
World birth rates are down almost everywhere except West Africa and Afghanistan. The entire developed world is within a point of one-child China (14 births/year/thousand adults), India is running less than double China's birthrate. There are still a lot of people to feed, and fewer wars to deplete the population, but the rate of growth is slowing. Yay us.
I have lived in Germany for about 22 years and I can tell you that there is no re-population of wolves and or bears. There was one bear that managed to wander into Barvaria, but was deemed to dangerous, and was subsequently killed !
I do seem to remember that there was an initiative to re-populate Wolves in the US. Dont know how that worked out.
It's all about stable states, nature has this ability to stabilize itself and humanity is not the exception.
There is a finite amount of resources on this planet, these resources ( even when optimally distributed ) will eventually force a decline in any massively growing population.
This is no secret, but part of the problem is that we, having the luck to have been born in a relative fertile geographical location, have a hard time considering the plight of billions of others.
And its these other billions that will be doing most of the suffering.
But there is also an even bigger problem, we are starting to upend the ecological stable state of the entire planet, and that will galvanize many other problems no matter where we are born.
Many people for many years have been talking about population declines, we have now recently reached 7 billion.
I'm just not all that alarmed about negative population growth in any area. What reason is there for replacement-level population other than caring for the aged? (I could be missing a lot of reasons.) It seems like it will be painful for the generations where the shrinkage occurs, and after that it will just be a smaller population.
Thanks - I appreciate your input. Although I grasp that the baby boomers are aging and may be a burden on a smaller next gen, it didn't seem like an actual population implosion, but there does not seem to be a lot of reliable data available.
