One Finite Planet

Population and Overpopulation

Population is a complex area. To arrive at my current point of understanding, it took me a number of light bulb moments over the years since 2013, with many realisations shattering some of my previous beliefs, and sometimes taking years to be ready to take the next step.

Here is a recap of my journey, and if you can move quickly from step to step, then you can absorb information faster than I can, but perhaps this information will inspire others on their own journey.

Reference

Anyone who believes in indefinite growth in anything physical, on a physically finite planet, is either mad or an economist.”

Attributed to Kenneth Boulding in: United States. Congress. House (1973) 

This applies to not just to population growth, but just maybe also to the growth in value of housing.

This page is a look at 'ghost cities' and 'ghost homes', and the window they provide into how distorted investment can become in the pursuit of growth.

The end result of the distortions can be overvalued assets funded by highly leveraged ordinary citizens. If that is the case, not just with ghost cities but beyond, the correction will clearly present a financial crisis.

The main surprise is that life expectancy reveals very little about how long people typically live. From the 1500s till around 1800, life expectancy throughout Europe hovered between 30 and 40 years of age, and it was only as recent as the 20th century, that life expectancy rose from 49.2 to 80.3 years. Yet famous historical figures from 2,000 years ago, typically lived to around 70 or longer.

Looking far back as we can know, a full lifespan has always been around 70 years or longer. The biggest change has not the length of a human lifespan, but instead, the dramatic increase in percentage of people who get to enjoy that lifespan. How ancient people lived was nothing like life expectancy suggests, and we have not yet extended lifespans to the extent you may think.

For the environment, our peak population will be a nightmare. This page explores alternatives for the future of population, and the possibility that the current peak population will be the last time there are ever this many humans on Earth.

When you look around, it is clear all other complex organisms on Earth have, and can maintain, an 'optimum population' level for their environment, yet there is a common perception that humanity is an exception, and seem to experience continual population growth.

This is an exploration of how optimum populations are reached, and critically are maintained naturally without overpopulation, and the implications for humanity.
