#humanpopulation — Public Fediverse posts

I gave one of my first-year university lectures today, on biodiversity and extinction rates, in which I mention the recent population growth of the Earth's most abundant large animal species ever: us.

I still remain completely gobsmacked by the magnitude of the world's recent human population growth.

8.27 billion: today's population, according to worldometers.info.

7.2 billion: in 2015 when I started teaching the course.

6.8 billion: in 2008 when my daughter was born.

3.8 billion: in 1971 when I was born.

2.3 billion: in 1946 when my parents were born.

1.9 billion: in 1923 when my Dad’s Dad was born.

So 1.9 billion to 8.2 billion in just over a century!

I worry about whether we can sustain this many people on the planet long-term while retaining and restoring a thriving wild biosphere that supports us.

Some of us are going to have to learn to use a lot less energy and resources.

The prevalence of experiences of discrimination among the Sámi is strongly connected to their language use and thus rooted in the cultural status dimension." https://doi.org/10.53779/SBPL3716 #Research #Study #DOI #PoliticalScience #Sami #Land #Policy #Human #Population #HumanPopulation #Inequalities #Norway #Sweden #Europe #Academia #Academic #Academics @politicalscience

Turns out, the 1982 UN Medium prediction for what the global human population would be in 2000 was nearly spot on (predicted = 6.119 billion; observed = 6.108 billion) #humanPopulation

Food for thought. The global human #population just passed 8 billion. Based on an analysis we've just completed, the most-plausible projections from the UN & IIASA-JRC indicate where we're headed #humanPopulation

According to Our World in Data, "Peak population growth was reached in 1968". Since then the growth rate has dropped even as the world's human population increases, but at a slower rate. In the future, "it will be low fertility [that] keeps population changes small."
