Population Explosion: What happened to get to 8 Billion people?

Population Explosion: What happened to get to 8 Billion people?

Humanity has just experienced a population explosion. Whether you believe we are overpopulated or not, the facts are that we have had a population explosion. A period of population growth that peaked at rate over 100x accelerated above the average over human history. Why? Not because of more food, the industrial revolution, or improved farming or access to fossil fuel, but due to modern medicine.

1.5°C by 2026? Already +1.25°C in 2021: What You Are Not Being Told Other Than By Greta Thunberg et al., And Why Not.

I started out wondering how much temperatures have risen so far, what is the best estimate for when will reach +1.5°C , and how bad is +1.5°C anyway. I expected that finding the first two answers would be easy, but it was not. I found the answers, and why they were not easy to find.

I found that with warming at +1.0 in Paris in 2015, +1.5 logically seemed 50 years away, but in 2021 just 6 years later, we are halfway there at +1.25°C. Much changed during the Covid-19 distraction, and at this rate +1.5°C is set to be here by 2026, not the 2050 predicted at Paris.

COP26: Were The Deck Chairs Sufficiently Shuffled?

COP26. It sounds like a police officer who can’t be named. For me it raises questions such as:

  • Why “COP26” and what happened to the first 25 COPs?
  • Are all decisions are made in advance, or is anything really agreed at the conference?
  • Is there more than politicians and fossil fuel companies agreeing spin and token gestures?

Peak Population: We May Never Return.

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.

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.

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.

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”.
