“The silence surrounding the global [human over-]population juggernaut is finally being broken, as we are seeing scientists, academics, activists, and policy-makers becoming more and more engaged in addressing it. Coupling immigration issues…” https://www.ecologicalcitizen.net/article.php?t=decoupling-global-population-problem-immigration-issues
Immigration to the population resulting from issues from coupling really is the nub of it.
Another issue-problem is that mis-typing “over-population” triggers the spell-checker suggestion “ovulation”.
“No one concerned with the state of the planet and the state of the global economy can avoid dealing with population. It is the elephant in the room.” (http://www.theguardian.com/world/2015/sep/24/popes-climate-stance-is-nonsense-rejects-population-control-says-top-us-scientist)
Planetary pregnant pause precedes pachydermic papal population pop.
“Climate change, war, reduced mortality and fertility, and increased maternal age … [even a] devastating global pandemic that killed 2 billion people” would only dent the human population. “Global population has risen so fast over the past century that roughly 14% of all the human beings that have ever existed are still alive today.” (http://www.theguardian.com/world/2014/oct/28/global-population-science-growth-study-wars-disaster-disease)
14% is startling. There have only ever been 50 billion humans? Over 20,000 years? A reasoned estimate puts this figure over 100 billion (http://www.prb.org/Publications/Articles/2002/HowManyPeopleHaveEverLivedonEarth.aspx) but any of the assumptions could be challenged. Still startling.
“Growth purely for its own sake is the philosophy of cancer.” (Jasper Fforde, Lost in a Good Book, Hodder Paperbacks New Ed edition, 2002, p86)
