Why does it happen? My first answer, it's dur to felting which happens mostly with sorts of wool that have a hairs with a scaled surface. Felting (when producing felt) is done by moisturing, heating and heavy agitation, so that the scales interlock at a compressed state and then stay that way.
Search turns up several ways of shrinkage though, for different types of fiber: felting, relaxation, consolidation, and contraction. Interesting to read --> Why Do Clothes Shrink in the Wash?
I used to be bothered by bat calls, and that's supposedly inaudible to humans.
Some species do partially chirp into the human audible range. But yeah it still requires moderately good hearing.
Societies would probably degenerate to absolute chaos. Relevant book exists: The Children of Men
film: Children of Men, 2006 (trigger alert: realistic brutality!)
Seconded. It is sick.
I didn't. My answer is as much guessing as the other funny ones. It's just the lamest one as in: if no other information is given then the question must be about the (true) semantic relation of the words themselves ... which there isn't because the accusation of treason is arbitrary. 😅

In a nutshell, many people are bringing in more or less useful comments although it has already been suggested how this could work; the changes required would touch some core functionality in the way federation is done/ links are handled, thus none of the new devs take the initiative; the two main devs are occupied with other serious stuff.
Apart from the list of items being somewhat generic and IP address just being unobtainable as someone else pointed out, it's just saying that they get data about users by means of the normal functioning of federation. It's ok in the same way as the server that originally hosts this community we are posting to (lemmy.ml) necessarily getting user data from our "home" servers we are posting from (feddit.de, sopuli.xyz), is ok. This is how we want it to work.
They would have to modify it for the other, "third party" server through which the user interacts with theirs, though.
There may be several answers to this. This is my somewhat simplified take.
One is, it's a (series of) physical action (heating, gasification, pyrolysis -- break-up of molecules of the fuel) and chemical reactions (oxidation). Oxidation means in general (in a commonly accepted model) that an atom shares away its outer electrons, which makes it acquire a lower energetic state. Oxygen is one element that is eager to attract such electrons for the same reason.
Whenever such a reaction happens, the superflous energy is released as a quant of electromagnetic radiation (a wave/particle) which we call a photon (it's therefore called an exothermic reaction). Photons can appear to us as visible light (that is wavelenghts in the visible spectrum). The wavelength of a photon inverse-correlates with the energy of the photon (blue > red).
Getting the reaction going however, requires the molecules of the fuel to get excited with energy in the first place, which is the required activation energy. This can be done by heating the atoms of the fuel. And as the oxidation also emits heat energy (far infrared), and in fact more than what is required for the whole phsyical-chemical process to happen, it can sustain itself (given the right conditions, see the second answer). This self-sustaining gassification, pyrolysis and oxidation we call a flame.
Flame colours are composed of the glow of gases at different temperatures ("red" is colder than "white") and the colour corresponding to the wavelength of the photons emitted in the oxidation reaction (simplified). In a typical candle flame, we see mainly hydrogen burning at the lower end (where the flame is blue but the gas is still reatively cold). Carbon takes a bit more activation energy (burns less easily), so it will start to oxidise farther up the flame where the gas is hotter. Carbon will make an orange flame at these temperatures. Other elements burn in all kinds of colours. A burning copper wire will make a flame glow green. Print colours on paper can contain metals which burn in different colours.
The other answer is how I explain how to make a "smokeless" campfire.
A fire needs three things: fuel (something to burn, wood), oxigen (air), and heat. Smoke is just the gases coming out of the wood condensating because they are either not hot enough for activation of the final combustion, or there is too little air getting into the hot zone of the fuel. Anything that is smoke could be a flame when the smoking part is put into a hotter place. Black smoke usually means that there is too little heat for the carbon to get fully oxidised. Cold fuel and having to evaporate water in the wood generally takes away heat from the flames.
TL;DR: A flame is a self-sustaining combustion process in a mixture of gases that needs to be hot and be steadily fed with fuel and oxygen. The gas is so hot that it glows.
I guess it means the DuckDuckGo Browser?

You seem to show some of your self-image here (a concept that replaces the misleading "ego"). The short description you give seems to tell that this is attached to "the quantity of your doing". Hence the idea of "living = doing more = becoming more" vs. "dying = doing less = becoming less".
While there is nothing wrong with that in principle (heaps of books exist on the different philosophical approaches on this wider topic and yours is quite popular among certain cultures), we could without changing much arrive at a different but perhaps more satisfying conclusion.
The change is from equating "living" to the experience of exercising our body and mind, to "living" being the experience of purely inhabiting and owning that body and mind. -- That would probably be what people mean when they seemingly tell you to paradoxically "live a little" (implying to mean "live a little more") by "doing less". Which, when we really concentrate on enjoying the pure experience will not actually mean that we are just idling but it would mean we would be less occupied with exercising and more occupied with observing the living (or observing the feeling of it). Whether we actually do physical/mental exercising or not does not really matter. It's just more easy for many people to do the observing while they are "idling" or "meditating" in a still way, but any way that fits a specific person is good. We might be surprised by how active we are when doing that.
That way we could arrive at the insight that "doing less" does not equal "becoming less" (perhaps even the contrary), neither that "dying" equals "becoming less". :-)
edit ... If we were to see "living" and "dying" purely as functions of an organism regardless of the existence of a self-image, then "living" would mean a sustained state of dynamic equilibrium whereas "dying" would be a transitory state toward non-equilibrium (that is decaying). Interestingly, decaying should then be a transitory state from being one dead organism into sustaining the equilibrium of living in other organisms (i.e. becoming the other); while there would be no transitory state toward becoming living (there's just a transition from being a single cell to being an organism).
