The Insidious Population Reduction Narrative Disguised as ‘Sustainability Science’

The latest example of Narrative Science has arrived dressed up as sober sustainability analysis: a paper that treats a smaller human population as the cleanest route to a cleaner planet.

It might sound like the evil plan of a nefarious villain, but scientists now say that we need to halve Earth’s population to save the planet.

Over the last 100 years, the world’s population has ballooned from less than two billion to 8.3 billion people.

However, researchers say our planet cannot sustain this explosive growth for much longer.

Now, in a proposal that will remind movie fans of Thanos’ plot in Avengers: Infinity War, scientists argue that the population needs to be ‘eased’ down to four billion by 2200.

However, rather than the instant destruction envisioned in that blockbuster hit, the scientists say that this could be managed as a gradual decline.

Scientists say we need to halve Earth’s population to just 4 billion to save the planet, per Daily Mail.

That framing used in the paper, published in Sustainable Development, is exactly what makes this genre so dangerous, as it takes a contested worldview, wraps it in charts and jargon, and then presents a deeply ideological conclusion as though it were merely the inevitable product of “the data.”
