"leading to more customers".
Where are you living that you get to pick your utility service provider?

Utilities have next to zero incentive to invest in/upgrade existing infrastructure, especially if they're privatized. It looks way better on the balance sheet if they just repair it when it breaks.

Reply to Social isolation is linked to classical risk factors of Alzheimer’s disease-related dementias by squigeons

Abstract

> Alzheimer’s disease and related dementias is a major public health burden–compounding over upcoming years due to longevity. Recently, clinical evidence hinted at the experience of social isolation in expediting dementia onset. In 502,506 UK Biobank participants and 30,097 participants from the Canadian Longitudinal Study of Aging, we revisited traditional risk factors for developing dementia in the context of loneliness and lacking social support. Across these measures of subjective and objective social deprivation, we have identified strong links between individuals’ social capital and various indicators of Alzheimer’s disease and related dementias risk, which replicated across both population cohorts. The quality and quantity of daily social encounters had deep connections with key aetiopathological factors, which represent 1) personal habits and lifestyle factors, 2) physical health, 3) mental health, and 4) societal and external factors. Our population-scale assessment suggest that social lifestyle determinants are linked to most neurodegeneration risk factors, highlighting them as promising targets for preventive clinical action.

You're thinking too much like a smart person.

You have to dumb it down for them. If they change now, it costs them money, and that's bad. So they don't change. Anything in the future is "potential" even if it's highly likely to occur, so right now all it would do is cost, no matter the future gains.

Reply to comment by real_bk3k 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

It solves the problem that people in cities have too-high emissions because our infrastructure has made them reliant on cars.

“Your proposal won’t fix anything, so we shouldn’t do it” is the argument on the side that doesn’t have arguments that are actually good.

I know your answer is money, but it seems like being able to more quickly adapt the technology and making it cleaner would be good thing, leading to more customers and mo ey down the road.

Most green roofs don't require tons of soil and watering vegetation. They're usually pretty thin layers of media and root barriers for grasses and other native plants to live, they're called extensive green roofs.

Intensive green roofs usually don't cover the whole thing, and have deeper layers and larger plants. They're much less common.

Reply to The antidiabetic drug metformin aids bacteria in hijacking vitamin B12 from the environment through RcdA (Jan 2023) by basmwklz

Metformin in combination with some kind of statin to lower cholesterol is common as well. I have that combination, and another side effect is dumping syndrome which also lowers your bodies ability to absorb nutrients. I was not told ever to supplement with B12, but I already supplement with other multivitamins to offset what I lose by dumping.

>because it's cheap and works well,

That's precisely why. If they can save a few cents, and nobody stops them, why would they change?

Sure. That doesn't solve the issue that so many people live outside cities. Even if you pretend they don't exist, their carbon emissions (including their cars) won't disappear.
