produce their meats

Billions of individuals choose to eat animal products giving money to factory farmers and industrial fishing companies - 2 industries that cause more pain and suffering than all other atrocities ever committed in all of history, combined (1-3 trillion fish are tortured to death every year by fishing companies, and at least hundreds of billions of animals are enslaved in torturous conditions in factory-farms every year). I live in a 3rd world country, and went vegan almost 20 years ago. For the people causing most harm: those in rich countries, it's easier to be vegan.

For those who can't grow their own plant-food, there's still this: https://ourworldindata.org/grapher/land-use-kcal-poore

Reducing emissions is a systems problem, it’s not about telling people to “be more green”

It's both: "No single raindrop believes it is to blame for the flood."

Corporations aren't causing a mass extinction just for shits and giggles, they're doing it because billions of individuals buy their products and services. If the billions of individuals stopped buying it, the corporations would stop making/offering it. The rich cause more harm in the short term, but even poor people having more kids despite the biosphere not being able to sustainably support even a fraction of the current population, are more omnicidal in the longer term.

It used to be mostly smoking; now it's mostly eating animal products and processed food, and poor sleeping. The advice given for decades is still valid: only whole-plant food and water, lots of exercise, and proper sleep.

Possible reasons listed in article:

  • obesity,
  • metabolic syndrome (abdominal obesity, high blood pressure, high blood sugar, high serum triglycerides, and low serum high-density lipoprotein),
  • added sugar,
  • processed food,
  • ultra-processed foods,
  • consistently high blood glucose,
  • insulin resistance,
  • change in sleep patterns (children sleeping less, shift work and artificial light),
  • microplastics,
  • antibiotics.

Biggest sources:

  • 7.6 Mt from macro plastics breaking down
  • 1.3 Mt from paint
  • 1.0 Mt from tyres

10-40 Mt released into environment/year, and increasing.

Answer: "The lifespan of these wasps is only 5 days"

"it's brain cells get rid of their own nucleus and all its stored maintenance information. The neurons already exist, so maintenance is the only task [...] requiring DNA, and they don’t live long enough for that to matter at this point"

"No nucleus or DNA frees up half of a neuron’s volume"

Edit: copying the font to /usr/local/share/fonts/ fixed it. (I downloaded Debian Xfce a while ago because of how much I dislike Snap, so I'll soon replace Xubuntu with it.)

I recently installed the font “Atkinson Hyperlegible” on Xubuntu 22.04.3 (via right click, Fonts 41.0), and I use it as the Xfce UI font and the default in Mousepad and LibreOffice without any problems.

However in Firefox 120.0.1 (64-bit), Snap for Ubuntu, canonical-002 - 1.0; it’s not listed at Edit, Settings, Fonts; or Fonts, Advanced…

When I view an HTML page where the CSS’ body has font-family:"Atkinson Hyperlegible",sans-serif; it also doesn’t use the Atkinson font. That page also doesn’t use Atkinson in the (Epiphany GNOME) Web 45.1 browser.

Any ideas on how to get Firefox and Epiphany to see it?

The crust is minuscule compared to the core and mantle.

The mantle makes up about 84% of Earth’s total volume. The temperature varies from about 1 300 K (1 000°C, 1 832°F) near its boundary with the crust, to 4 000 K (3 700°C, 6 692°F) near its boundary with the core. https://education.nationalgeographic.org/resource/mantle/

The temperature in the Earth's core is uncertain: estimates at the inner core boundary range from 4 000 K to 8 000 K and at the core–mantle boundary from 3 000 to 4 500 K. https://www.homepages.ucl.ac.uk/~ucfbdxa/pubblicazioni/nat.pdf

Wouldn't an honest title state that a certain flu variant now seems extinct? Why spread a title that makes it seem like the vaccines are unsafe?

Please downvote distortions like this.

"On oil and gas companies who have spent decades burning fossil fuels - ramping up the world’s carbon emissions - Mehta said the law couldn’t go back in time and punish past activities."

Since we gave people the death penalty at the Nuremberg trials ex post facto, we can do the same with anthropogenic climate change. I would support such death penalties now already, tho I suspect more than a hundred million people would have to die directly from unambiguous climate change events within a short period like a week, before more people would agree. The problem is that the climate-change tipping-points will cascade, which means that the 1st one may cause other tipping points to be triggered, at which point billions of people will die unnecessarily in a Mad Max world.

"Enslave" is a bit harsh, considering there are about 38-50 million people who are currently slaves https://en.wikipedia.org/wiki/Slavery_in_the_21st_century

We're choosing to allow a lot of the things these companies are doing to us; but we could choose to walk away at the cost of some shiny things.

To view a text only version of CNN pages, replace "www" with "lite". https://lite.cnn.com/2023/07/26/economy/china-youth-unemployment-intl-hnk/index.html is about 50 kB, whereas the original is about 2.7 MB.

Did the Staten-Generaal supervise the Heeren XVII, was it the other way round, were they usually the same people, or did it not work like that?
