The #koala #Phascolarctos #cinereus (Diprotodontia) is a threatened species in Queensland and New South Wales, which, however, according to F. Saltré et al. (2026), has an excessive #populationdensity in #Australia's #MountLofty Ranges, leading to mass starvation, which is why fertility-control strategies for conservation may become necessary

Not exactly. What the issue is is "the cold parts of Canada are too thinly populated to have the electric infrastructure necessary for quick charging to allow you to travel between cities reliably in the extreme cold". We can discuss the details - the math shows pretty conclusively how electric vehicles are not an alternative in a lot of situations in the prairies and the north - but it's all stuff I've gone through before. If you're one of the "just switch to electric already!" city-dwellers from lower BC or the Windsor-Quebec City corridor who's never lived elsewhere, you really don't have a frame of reference for this.

"Canada is too cold for electric cars" is a straw-man argument that nobody is making.

Also, the problem is not #overpopulation, the problem is spots of high #populationdensity. Big difference. A vast interconnected network of small self-sufficient villages/cities in exchange of support based on mutual help is long therm sustainable. Of course it doesn't suit if the goal is to make profit off of other people's work.

A new article in *Science* summarizes ongoing changes in demographics and fertility, but identifies only economic and health-related factors as likely drivers (https://www.science.org/doi/10.1126/science.aed1652). It fails to acknowledge the strong negative relationship between population density and reproduction that is seen throughout the animal kingdom and also in humans (e.g., https://pmc.ncbi.nlm.nih.gov/articles/PMC8549112/).

Overpopulation (Zoology 🦥)

Overpopulation or overabundance is a state in which the population of a species is larger than the carrying capacity of its environment. This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for ...

Reevaluating the World's Most Densely Populated Islands: A Closer Look at Population Data

The article dives into the true statistics behind claims about the most densely populated island in the world. Common reports say Santa Cruz del Islote, a small artificial island off Colombia, holds this title, but closer examination reveals discrepancies. The population is actually 779, not 1,200, ...

“Food deserts are not an inevitable consequence of poverty or low population density, and they didn’t materialize around the country for no reason. Something happened. That something was a specific federal policy change in the 1980s. ... Food deserts will not go away until that mistake is reversed.”

The original map was printed in Black and White and hand coloured using colouring pencils on hand. The purple originally didn't differentiate enough with the lighter pink so heavier pressure was applied.

@james I could see that happening, but maybe it will result in small cities of 50k people at higher #PopulationDensity, surrounded by farmland, rather than a low-density sprawl/spread.

Indiana is the 16th most densely populated state in the USA, but this region in the hills of south-central has about the same population density as much of West Virginia. It’s very rare that I see anyone else in the state forests of eastern Monroe or western Brown Counties when I’m out hiking. #Indiana #PopulationDensity
