Cool. Thanks for taking the time. God speed.

The first prediction is if a person lacks the will to not check their phone - they will fundamentally be incapable to leading independently from the cultural opinion-machine - they will continue sucking on that teat, never truly having any of their own life experiences, and forever living vicariously through those who do.

One other thing about concrete that gets glossed over a lot is that it requires sand dredged up from riverbeds and other places where it is water tumbled. Wind tumbled sand, like what you find in deserts such as the Sahara, is unsuitable due to its smooth shape.
Demand for concrete in construction is contributing to erosion of riverbanks and other habitat destruction in this way.

They've already invented carbon negative concrete. They just don't use it due to cost. Is this process going to be cheaper than traditional concrete/steel? Probably not, so it will not be used as well unless we start mandating it.

So, how do we stop these insidious chlorophyllian invaders? Blow up the mountains?

Really figures that even Russian trees don't work right.

I mean yeah but environmentalists will oppose it because the word "GMO" is scary. I was just reading about the opposition to this exact thing the other day

Yes, but most man-made wooden structures do not catch on fire. They just sit around, sequestering CO2 for a long period of time.

Reply to Developmental predictors of young adult borderline personality disorder: a prospective, longitudinal study of females with and without childhood ADHD by BlitzOrion
I wish I could explain how hard BPD is to those that don’t suffer from it.
The best explanation I’ve seen is it’s like a 3rd burn of the emotions that’s constantly being poked.

Doesn't that mean that all the captured C02 is then released into the atmosphere?

From my quick google aearch I can see that's the consensus, but it still isn't the worst emmiter for being the most produced resource which is pretty surprising. It's thrid.

good idea. nice..
however, what I see is just gymnastics so people can continue to add to the population growth. in the end whatever gain will be made by a technology like this will be eaten up by the increase on population. maybe it is supposedly slowing but I don't see it coming in time.
still a good idea. doubt it catches on

Okay, but how does that make it number one? I feel like there are many other I dustries, such as rare earth mining and iron working that requires the same amount of energy if not more.
What makes the concrete industry the worst as you put it?

Because to make cement for concrete, you heat calcium carbonate (limestone) to drive off carbon dioxide to make lime (calcuim oxide). This process is energy intensive, requiring quarrying equipment, crushers, heating, cooling and grinding, as well as emitting vast amounts of carbon dioxide as waste product.

Some places did. The plant near Raleigh, NC generates enough power for about a million people, although additional reactors that were planned ended up getting cancelled. About a third of the states energy comes from nuclear. Hence why rates are still $0.12/kWh there.
Or, as an alternative, I live in Washington now, where much of our energy comes from hydro, and we're at $0.10/kWh.
Our country needs to be smarter about who we vote for. Infrastructure and a variety of other issues should come way before a minor tax break, yet people seem willing to sell their soul for a few more dollars up front. We end up paying that tax break back many times over to predatory private industries, widescale power outages, inflation / national debt, and numerous other very obviously forseen consequences

Check out the work of Dr. Chris Palmer. He has been doing a lot of interviews re: his new book Brain Energy.
Both bipolar and Alzheimer's have been linked to insulin resistance, along with diabetes, NAFLD, PCOS or ED in men, mood disorders, heart disease, some cancers and Alzheimer's. Dr. Ben Bikman's book Why We Get Sick is excellent at laying out the common underpinnings.

Reply to Reflexive fear responses tend to linger in people with anxiety disorders, study suggests by chrisdh79
From the article: People with and without anxiety disorders learn to fear a threat equally quickly, according to new research. However, people with anxiety disorders tend to have a harder time learning to stop being afraid on a physiological level (when the threat is gone) compared to healthy individuals. These trends can be detected by monitoring fear-potentiated startle responses.
The study was published in the International Journal of Psychophysiology.
Learning to recognize threats is a capacity that is of extreme importance for survival. However, problems in these processes, such as situations when an individual easily learns to associate certain stimuli with danger but fails to extinguish this association once the stimuli in question are not longer associated with danger, have long been linked to the development and maintenance of pathological anxiety.
Some theorists have linked the fact that anxiety symptoms start developing in late childhood and early adolescence with variations in the maturation of neural circuitry supporting threat learning. This is often explored experimentally by using the so-called differential threat conditioning study plans.

There was some analysis a while back saying much of it was about half and half actual scarcity vs corporate greed. That's just the nature of the economics of monopolies/oligopolies, and exactly why they should never be allowed to persist. Although I think that 50-50 was in reference to all goods, not fuel particularly, so maybe it was worse for fuel
