Reducing prairie dog concentrations, and most often killing the weaker slower ones, which are likely infected and showing the most symptoms.

Reduces spread and increases evolutionary pressure to increase resistance and possibly even become immune.


Led, mercury, cadmium and arsenic are showing up in so many foods. In rice in spinach and obvious in fish.

Microplastics and PFAS in fruits and fish and everything else.

And the most recent TV report on cadmium in spinach, I watched, told me to have a diversified diet.

Diversified into WHAT?


A diet with balanced between cadmium, lead, mercury, arsenic, microplastics and PFAS obviously.


On the other hand, the US is close to bankruptcy. And that's not all the current admin's fault.

And their cuts are trying to avoid that, although they have thrown out many babies with the bath water. It's hard to blame them for trying to avoid default, which would be far worse than anything.

The program apparently cost $900 million which is not a trivial cost.


Yeah, except for the tax cuts for the wealthy which created more debt than all of their other cuts combined, and then some.


Carbon neutral as long as your electricity is carbon neutral.

Also many steel mills are built so that they can switch between energy source, oil, coal, gas, which ever happens to be cheapest currently.

It's a commodity business, price is almost all that matters. And with the current US Administration the days of carbon subsidies might be numbered.


With this approach, a waste heat energy recovery system could reuse a significant percentage of the energy.


Addictive tech in your hand is an evolutionary trap.

Much like cars are to squirrels, squirrels have evolved to run into a straight line to the nearest tree at the hint of any danger. And for all threats other than cars that is the correct thing.

But many squirrels are "trapped" by evolution to cross the path of a car when there is no need to do so.

Humanity's curiosity, sociability and OCDness have all been trapped by algorithms and smart phones.

And it is shortening lives and even more so reducing reproduction. A faint hope is, that with all such evolutionary pressure, we can evolve our way out of them.... eventually.


I find it interesting ever more risky way to sequester carbon are invented.

Instead of making adding biochar to farm land an agricultural subsidy. A simple, extremely low risk policy, that is a local subsidy and does create international trade conflicts like other subsidies can.

And it does not affect any wilderness.

And in hot humid climates is proven to increase fertility.

Or a bit risky we could fertilize the open ocean, very significantly increase ocean life. And it has been proven that a significant percentage of fish poop sequesters carbon in the deep ocean.

Instead efforts seem to be focused on shading the sun. And new ideas using nukes....


The potential benefit of this idea is it's very cheap. One penny per ton vs hundreds of dollars of per ton of biochar.

Iron fertilization, shading the sun, and more nukey-stuff, all worth exploring at this point.


Can you tell me, without looking up, how many gigatons of carbon are in the atmosphere and how many are added by humans each year?

Yeah, it's 'simple' until confronted with the sheer scale of it


Does biochar remain in ground for long? How quickly does it decompose and rot?


That is pretty variable I would think due to ground composition and how complete the char burn is. In my anecdotal experience, if you do a low grade charcoal that still has a decent amount of oils in it like a lot of old-school burn wood and bury it in earth or drench in water, most of it will have broken down to invisibility after just a few years or so mixed into the ground. However charcoal that I have burned in a container sealed from air ingress and using a secondary source of heat until the wood stops venting any gases and is nearly pure carbon, I still see decent size chunks of it in my garden areas over 2 decades later, and no reason to expect it to not still be there even 50+ years from now.


The current best in class methodology for biochar aims for 100+ years. There are some folks saying there are pathways to make biochar last 1000+ years.

Puro methodology: https://biochar.groups.io/g/main/attachment/32853/2/Puro.ear...

The nice thing is biochar is relatively inert. It just sits there in soil, holding onto water, making space for organisms to grow, but isn't "food", so it doesn't get eaten up and turned back into carbon dioxide. So it's a win for farmers and carbon removal.


7 to 10-ish years from what I recall. Which is another thing that makes it so low risk. If you stop the subsidy it goes away with a few years.


You're doing great, keep it up!


I think there's still appeal in the underlying (very) basic ideas of trying to create a workplace that's comfortable for everyone.

If copyright forces a diversity of AIs. That would be good.

Every AI company using its own created training, resulting in AIs that are similar but not identical, is in my opinion much better than one or very few AIs.


Japan used to be known as the one nation in the world where old people were fans of bran new tech.

However, today it would seem that's because that generation lived through the great changes Japan experienced. Extremely quickly going from a pre-industrial civilization, to a post-industrial one.

And so despite Japan's great traditionally intense conservatism, they were fans of technological innovation.

With that generation fading away, it seems Japan is returning to being hyper conservative in every way. And falling behind technologically.

The story of Shuji Nakamura, inventor of the blue LED, is interesting. The company founder supported his experimentation, but the next generation, the son of the founder, wanted to Shuji Nakamura to stop.

Faith in innovation vs pessimism.
