Reply to comment by Billbat1 in Endangered male northern quolls are giving up sleep in favour of having more sex – and it could be killing them, according to a study that investigated why male northern quolls usually mate themselves to death in one season while females can live and reproduce for up to four years. by MistWeaver80

Some people think that because of this it is morally worse if women die than men. E.g. when Russia commits terrorist attacks in Ukraine, it is stressed more if women died in the attack.

Males are less important. You can lose one male and it has no impact on the next generation, because it's easy for the other males pick up the slack.

If one female dies, that's a whole litter of pups that are missing from the next generation.

Reply to comment by RagnarokDel in Planting more trees could axe summer deaths by a third. Modelling of 93 European cities finds that increasing tree cover up to 30% can help lower the temperature of urban environments by an average of 0.4°C and prevent one in three heat deaths as a result. by MistWeaver80

Can't even get home owners to take care of benefitial green spaces on the ground, they aren't going to be able to do it on their roofs.

males are less important for the survival of a species. 1 male can mate with 10 females. but not the other way round.

Cars will never go away in places where everything is far apart. Mass transit can be great for cities, but becomes less practical outside them.

Then they should use "terrestrial". Using "Earth" creates expectations in people's minds that are far beyond anything meant by "super-Earth" and leads to broad misunderstanding of the science. Look no further than the word "theory" for how damaging this can be.

Reply to Long-term exposure to even low levels of multiple ambient air pollutants, association with depression, anxiety by 9273629397759992

So bad air makes people feel bad and potentially do bad things, sounds about right.

I have this weird theory that native Hawaiians had an understanding of pollutants and microbes as they referred to the first European visitors as haole, which translates to “without breath” and the concept of “breath” is like a universal life force and aloha translates like “sharing breath”.

So I imagine when native Hawaiians, who practiced sanitation and hygiene, saw visitors come off of a boat that was cramped, dark, dirty, and with poor sanitation, they inherently know that these sailors were covered in and breathing bad air/life force.

When talking about heat deaths wouldn't it be more relevant to talk about how much tree coverage changes the peak temperatures? The average temperature is irrelevant because people aren't dying from being at 21.4 C rather than 21 C on average.

i think it would be fine for industry and workplaces where you barely see sunlight anyway, but for mental health reasons building housing underground is a terrible idea yeah

Plain language summary:

This study found that long-term exposure to air pollution may increase the risk of developing depression and anxiety. The study looked at nearly 400,000 people in the U.K. and found that exposure to PM2.5, NO2, and NO was associated with higher risk for depression and anxiety. Even at relatively low levels of exposure, all three pollutants were linked to depression and anxiety. The risks for depression and anxiety were higher in the second, third, and fourth quartiles of exposure compared to the lowest quartile. The authors suggest that air pollution may increase mental health issues by causing inflammation and oxidative stress in the central nervous system.

That joke unfortunately falls flat on the yanks, they don't have the same connotation of "rooting". There's a plumbing business called roto rooters in the states, gives me a good chuckle every time I see once of their trucks. Along with the "coït cleaners" from SF

….2.1 million cars? California alone almost has that offset with their close to a million EV’s. It feels like we’re barking up the wrong tree here
