I think asking is good, and this may be worth getting into for other reasons - but know that this is a one way trip.
I'd suggest starting with the things that helped me unfuck my shit (partially, anyway!). First, if you haven't already, check out Kurzgesagt's Optimistic Nihilism video. If you find that interesting, continue on to absurdist philosophy, especially Camus (Sisyphus, Stranger) and Sartre (Nausea). After that, existentialism - I think I'd probably start with Man's Search for Meaning by Viktor Frankl.
Once you begin to get a feel for these ideas, I think a high-level reevaluation of deeply held beliefs and how you perceive the world around you becomes inevitable.
In terms of your question and what you are seeing, I believe these trends represent a larger collective awakening. Not a miracle, but something borne out of necessity: for anyone brave enough to take their head out of the sand for thirty seconds, environmental concerns alone are completely fucking overwhelming, and obviously that's just a start.
I do take solace in this development, though. Somehow, even without actively studying philosophy, teens today (and even younger!) appear to have, to a degree, an intuitive understanding of these concepts. That's wild! When I was in high school in the late 90s, genuinely thinking for yourself wasn't tolerated the way it is today. Sure, there were punks and goths and whatever, but for anyone who dared to question the paradox of asserting one’s uniqueness through group affiliation, the road was much bumpier than it seems to be today.
I actually had to remind one of my children at around 10 years of age that she should be careful telling her peers things like "god isn't real and nothing really matters" ... admittedly she was raised in a "we always respect people with different beliefs even if we find it difficult to respect their beliefs" home, so the "god isn't real" part wasn't a surprise, but she found existentialism on her own.
Consider the complexity of the humour in memes today - I think a lot of older folks dismiss it as vapid and banal, and while some definitely lands there, the baseline tends to include a lot more irony, sarcasm, and even elements of these more abstract philosophical ideas in ways that older generations tend to struggle with. At first glance it appears completely nonsensical, but upon superficial understanding it quickly becomes "antisocial" and offensive: how dare you find camaraderie in joking about suicide, and do you really think the collapse of civilization would be a good thing? This is more than gallows humour.
And perhaps your comment was more flippant than my initial interpretation and this will just come across as obtuse and condescending - I hope not, as that is definitely not my intent. If it was sincere and you are just beginning down this path, I hope my perspective makes a difference for you. I suspect it is obvious, but my own experience with this was not pleasant; it took me many years to find my way through and feel ok about continuing, in the broadest sense. With a bit of discipline and thoughtfulness, I think you should be able to mitigate the psychological risks inherent in exploring some of the more fundamentally challenging implications of nihilism.
No, you can't. Yes, you are missing the first law of thermodynamics. The refrigerator doesn't 'make cold', it moves the heat from the front to the back. Pull your refrigerator out and you will notice the back is very warm.
If you put the back of the refrigerator out your window, it would cool the inside of your room, but it wouldn't work as well as an air conditioner because it is designed to keep a very small highly insulated area cool. Air conditioners use the exact same principle, but they are much more powerful because they need to move a lot more heat.
I know this is the cliche joke, but it's fucking tired - especially considering the fact there is nothing unique about Taco Bell: they pass food safety requirements just like every other shitty fast food restaurant. If you can't eat a few beans without experiencing GI distress, your diet is the problem, not Taco Bell.
How is it ridiculous? If someone wants to end their own life, oxygen deprivation is possibly the most peaceful way to do so. In fact, many folks choose to end their lives with dignity by closing themselves in small "gas chambers" specifically designed for this purpose.
It isn't an opinion, though, you are simply failing to follow the conversation. I said "the method itself", which implies that I am comparing this method to other methods and NOT discussing whether or not capital punishment is ok.
How sensitive are you? I've found I struggle with them a bit if I eat lots suddenly after not eating them for a while, but if I continue, it tends to be fine. My guess is that the reason it is inconsistent for me is related to fluctuations in gut bacteria partially due to what I am eating...
I know actual IBS is no joke, but I think it would be interesting to determine your threshold and see if you can change it at all. For example, eat a pea-sized piece of onion and wait a couple days. No effect, start eating a pea-sized piece of onion every day and wait for cumulative effects (a week or two?). Still no effect, add another piece for one day, go back to regular dose for a couple days, etc. When you reach the point where it starts to cause discomfort, back off a bit and try to push it again in a week or two.
I know a lot of people die accidentally this way, but I wonder if it's always peaceful. I had to take oxys once and - granted, the dose was minuscule - I experienced some pretty intense paradoxical effects for a while before I noticed any degree of sedation. Would giving 100x guarantee immediate sedation and respiratory shutdown, or would they be convulsing and puking everywhere on their way out?
Where do we even go from here, though? We should've saved this one for the end.
