Reply to comment by [deleted] in Scientists have figured out a way to engineer wood to trap carbon dioxide through a potentially scalable, energy-efficient process that also makes the material stronger for use in construction by giuliomagnifico
A mature oak tree weighs somewhere around 2,000 tons.
The average American generates 16 tons of carbon a year. That’s 125 years of emissions covered.
So each tree does quite a bit

>And they're kinda dangerous. They get to 30-35' tall, then just randomly fall over.
The soil probably isn't right. Russian olives are banned in my community because of this. They blow over in wind. But, in some parts of the country, they are used as wind breaks! They need rocky soil for their roots to wrap around and get a grip.

Reply to Globally, the total cost of energy for households has likely increased between 62.6% and 112.9% since Russia invaded Ukraine, say international researchers. An additional 78–141 million people worldwide could be pushed into extreme poverty as a result of these increases. by MistWeaver80
This is still a result of capitalism, though. The economics of it is just back bending on everyone else's part to keep the wealthy wealthy.

Considering mindfulness meditation predates bmt by millennia I don't think so.

Reply to Developmental predictors of young adult borderline personality disorder: a prospective, longitudinal study of females with and without childhood ADHD by BlitzOrion
Background Research on the precursors of borderline personality disorder (BPD) reveals numerous child and adolescent risk factors, with impulsivity and trauma among the most salient. Yet few prospective longitudinal studies have examined pathways to BPD, particularly with inclusion of multiple risk domains.
Methods We examined theory-informed predictors of young-adult BPD (a) diagnosis and (b) dimensional features from childhood and late adolescence via a diverse (47% non-white) sample of females with (n = 140) and without (n = 88) carefully diagnosed childhood attention-deficit hyperactivity disorder (ADHD).
Results After adjustment for key covariates, low levels of objectively measured executive functioning in childhood predicted young adult BPD diagnostic status, as did a cumulative history of childhood adverse experiences/trauma. Additionally, both childhood hyperactivity/impulsivity and childhood adverse experiences/trauma predicted young adult BPD dimensional features. Regarding late-adolescent predictors, no significant predictors emerged regarding BPD diagnosis, but internalizing and externalizing symptoms were each significant predictors of BPD dimensional features. Exploratory moderator analyses revealed that predictions to BPD dimensional features from low executive functioning were heightened in the presence of low socioeconomic status.
Conclusions Given our sample size, caution is needed when drawing implications. Possible future directions include focus on preventive interventions in populations with enhanced risk for BPD, particularly those focused on improving executive functioning skills and reducing risk for trauma (and its manifestations). Replication is required, as are sensitive measures of early emotional invalidation and extensions to male samples.
“First, findings highlight the longstanding effects of early experiences of adversity and trauma. Prevention of these childhood experiences, especially through public health initiatives, cannot be overemphasized. Second, our results reveal the importance including global executive function (EF) deficits in childhood as indicators of risk for BPD, in addition to the focus on childhood impulsivity. These findings have implications for guiding early clinical assessment and intervention (e.g., through early EF skills training) to prevent later BPD. In short, we highlight the need for interventions before the adolescent period, which appears to be an especially sensitive time of risk [11].”

A Zen practioner I knew would travel 2 hours a couple of times a week on her own dime to teach mediation to prisoners at a state prison. This was entirely selfless to help prisoners keep calm and also (hopefully) control outbursts.
Even though prisoners wanted the opportunity it took her a very long time of advocating to do this. The Christian chaplain and warden didn't want Buddhist influence in the prison.

Hmmm… …seems like the origins are still being debated. This hermit dig does seem to provide evidence of pre-Colombian syphilis in Europe but it’s still ambiguous whether the disease we know it as today came to Europe via the Americas. A similar finding from a century or two earlier would be more conclusive though one could still make the argument that Vikings could have brought it to Europe though that seems like a huge stretch considering the first recorded outbreak was in Naples in 1494/5. The European origin still has many plausible hypotheses between it being confused with leprosy and the possibility that the outbreak in Naples was from a mutation of a precursor. So yeah…. …who knows.

Reply to comment by Lonny_loss in Plants are spreading up mountains faster than thought in North America by BlitzOrion
Alpine meadows, natural ones, grow in places where it's hostile for trees. There are multiple stressors that are correlated with altitude.
Here's an intro article: https://www.encyclopedie-environnement.org/en/life/how-do-plants-cope-with-alpine-stress/
If you're thinking of semi-natural (man made) grasslands in mountainous areas, then, yes, the succession to trees is natural.
Mountains are hotspots of biodiversity. But the climate warming effect is known already: as the climate is warming, species are moving up the mountain, and it's not just plants. The mountain gets narrower towards the top, which leads to more crowding, and the species at the top already have nowhere to go.

Applying some fancy co2 absorbing material to wood makes the material work 8 times better and also makes it more stable or something.

Yes, resulting in a net-0 change -- the CO2 that went into it is equal to the CO2 that is released from burning it.

It's been tried with great success. Until parents found out. Usually the christians. They've gotten various programs shut down multiple times in multiple locations. Chicago, Georgia, Australia.

Ok, your comment got me wondering as it seemed like if it was originally from the Americas, it would have been the first disease I'd hear about doing this.

Where do you think they find the carbon they need to grow?

82.1% of students self-reporting improvement is quite promising. I've always been of the belief that meditation/mindfulness should be taught in schools. So valuable in this age of unlimited distractions.

Awesome. Now let’s convince the majority of people to reduce their production of carbon emissions along with this.

I tried to read most of the study, does it speak to variances in extreme temperatures or weather conditions (hail, wind)? Trees to not do well at high altitudes for generally one reason, high winds mixed with significantly low temperatures. If we're seeing a warming trend, I wonder if extreme lows are also climbing.

Yet another reason we need to support Ukraine in getting Russia tf out of there.
