Reply to comment by My_Body_The_Mystery in Scientists create carbon nanotubes out of plastic waste using an energy-efficient, low-cost, low-emissions process. Compared to commercial methods for carbon nanotube production that are being used right now, ours uses about 90% less energy and generates 90%-94% less carbon dioxide by Wagamaga

>Also plastics should be easily categorized.

They in fact are.

You can use cheap-ish near infrared spectography to tell em apart. https://www.oceaninsight.com/blog/spectroscopy-for-plastics-recycling/

​

Really the issue is how ridiclously cheap it is to "mine" the base mineral (oil), making it utterly uneconomical to recycle even when its technologically feasible.

Reply to comment by [deleted] in Climate change and the projected savannization of the Brazilian Amazon threaten most land-based mammals that live there, new research shows. The “savannization” here refers to when lush rainforest gives way to a drier, open landscape that resembles savanna but is actually degraded forest. by MistWeaver80

> When you have few opportunities a job is a job even if long tern that job ends up being bad for you and your family. You still do what you have to.

True but irrelevant. The poor, shirtless peasants of Brazil do not have access to the bulldozers and chainsaws necessary to cut down the Amazon, the massive trucks required to drag out trees, the markets to sell them in, nor the mercenaries needed to murder the indigenous people who live there.

The rape of the Amazon is being driven by Brazil's rapacious oligarch scum. The poor they employ to do some of the dirty work are mere pawns.

Reply to comment by Sherlock-Holmie in Physicists nail down the most precise value yet of the electron magnetic moment. A newly measured value of an electron’s magnetic moment — a property of its spin and charge — is twice as precise as the one physicists have used for the past 14 years. by MistWeaver80

Theoretically, couldn’t you use the spin direction of an electron as yet another means of computational processing strength in microchips? Like, if a microchip consists of a bunch of atomic “switches” that are either on or off, and you had another controllable variable (spin direction) you could incorporate, wouldn’t that mean that you could have dramatically greater chip processing power? Full disclosure I have no clue what I am talking about.

> Better policing and policy is great and all but if poor people are still poor left with no other way to better themselves what else do you expect is going to happen? With no other option people will exploit local natural resources to better themselves.

You're thinking like a WEIRDo - western, educated, industrialized, rich and democratic.

Almost all of the inhabitants of the Amazon are uncontacted or barely contacted indigenous peoples who don't share a single one of your values or aspirations. They largely live today as their ancestors lived in the stone age and they are quite content to do so. This means they live in small bands of no more than a couple hundred, build transitory shelters that they use for no more than a year or two, hunt and gather for food, and then move on to greener forest. The damage they cause to the environment self-heals in a couple years, and so their lifestyle is sustainable.

They do not premise their lives on infinite growth and accumulation, the core requirements of capitalism. They do not exploit resources more than is necessary to live their lives.

The Amazon needs nothing more to thrive than to be left alone by Brazilians and other western neighbors.

I've read more on it and people's ability to process strong emotions(like people with bpd) but I'm having trouble finding it right now. Here's an article I'll post more if I find it:

Because of the nature of the illness it is very difficult to prove the relationship one way or the other. Because of this I would say the science is not clear on the issue but there are good theories both ways.
