“As Limits to Growth concluded in 1972: If the present growth trends in world population, industrialisation, pollution, food production, and resource depletion continue unchanged, the limits to growth on this planet will be reached sometime within the next one hundred years. The most probable result will be a rather sudden and uncontrollable decline in both population and industrial capacity.

“So far, there’s little to indicate they got that wrong”.

Human Population Cycle

Current world population: 7.4+ billion

world pop growth Recent Human Population Explosion

Ecologists have described numerous examples of boom and bust population cycles in which the explosive growth of a species’ numbers is followed by rapid decline.  Compared to the population cycles of other species, the human population’s global extent and impact are remarkable.  Our technology has helped us spread across the globe harvesting resources, and changing soil, water, and plant life far more than any other species ever has.

Consequences of Our Population Explosion

Human population impacts take many forms.  Here’s an example that may seem insignificant until one considers how often this happens around the world.

One thought on “Human Population Cycle

  1. “Limits to growth” with humane justice were already surpassed when the book was published. Now we’re simply past all limits to growth and any “forward’ motion can only happen by a massive bite taken from the environment, nature and humanity’s plummeting quality of life. The current growth entropy is irreversible. The hypocritical but inevitable Sanders’ cave in to Clinton and his traitorous about-face is indicative that there is simply no longer any “moral high ground” space available in any human sphere of influence through establishment power. The “free” energy that fueled capitalism world-wide is gone. My opinion.
