My Journey To Understanding Population.

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.

Why Population growth even before the explosion?

Throughout history, although no other species on Earth has experienced such long term overall population growth, even before the recent population explosion, the human population kept slowly growing.

Yes, we recently had an unprecedented population explosion, driven by is hidden by by the near elimination of previously tragic infant mortality, but against the background of long term growth, many of us never didn’t even realise their was an explosion.

But what drove population growth even before the explosion? What will now happen as the explosion ends?

Optimum Population: nature’s birth control.

What controls population in nature? Why is overpopulation rare? Predation and resource constraint are commonly suggested answers, but in practice these alone would result in repeated huge population swings.

Human birth rates are falling at a rate that has some fearing population collapse, but is there reason for alarm, or might this be a natural response to the threat of overpopulation?

Determining whether our future is population one of continued growth, collapse, or stability, almost certain requires understanding lessons from nature and examining how they apply to us.

Population on a Finite World: No Vacancies.

Every niche on Earth where life is possible, fills to maximum capacity with life, meaning except for brief periods following Earth changing events, there have been no ‘vacant’ liveable environments for over 4 billion years. Any increase in population of one species, requires a reduction in numbers of other species, in a process Darwin declared “survival of the fittest”.
