Never underestimate just how clueless the general population is about how the world works. More than you'd expect would prove to not really grasp even the most basic mechanisms of their environment.

People turn to religion for a reason.

To the majority of people, understanding the world beyond "inexplicable god magic" is difficult to learn good-for-nothing trivia unless it's needed for a good grade and maybe a job if you're cut out for it. Only the parts specific to surviving in the wild get a different treatment.

Even the non-religious seem to make a habit of thinking like this. The kind of "not a Christian" alcoholic that is completely disinterested in the actual philosophies that allowed for a world where open disbelief is safe, and vocally in favor of "rights" of some sort for currently relevant minorities, with maybe a rare acknowledgement of some surface-level misunderstanding of humanitarian ethics.

You completely missed the point.

This was about the elegance of the answer, not the answer itself.

My first thought, when I heard that question, would be "do we have a backup in case the naturally produced oxygen for some reason goes away?" like some families have an emergency supply of food or water, not that the child did not know that Earth's atmosphere naturally contains oxygen thanks to plants.

It wasn't about wanting to know about photosynthesis, the original question was really about the oxygen tanks. Kids very often are looking for a simple answer. Even though the real answer is far more complex.

As a Dad who helped raise 4 Daughters, (a CPA, a Triage Nurse, PHD Mech Engineer, and a Computer Forensic Expert for the FBI), teaching at home is a crucial part of parenting. Beyond offering a wide variety of materials to learn from, (we built a library of books that filled my office), and being ready to answer those oxygen tank questions, you need to show and make asking those questions and learning from them fun.

To add to this: At 3'500 meters above sea level, the pressure is down to 2/3 atmospheres. So instead of 21 kPa of oxygen partial pressure, it is only 14 kPa. So like breathing 14 % oxygen at sea level. People live at that height.

Dumb question, but in a very oxygen rich environment, can you just breathe through a paper bag or something? Mostly just breathe your own exhaled CO2 with a bit of O2 leaking in?

It is (I hope) an original. Though the form "my grandfather would tell stories" might be bordering on cliché.

This is just your “one of today’s lucky 10,000” moment.

So, Lemmy. Lemmy is where you find one.

Happy belated father's day, from someone who is glad you made this comment. I appreciate you highlighting this issue, because this is something that is sorely lacking in progressive discourse; it's getting better, I think, but that is likely due to people like you helping people like me to understand how caring fathers are usually not respected or appreciated by the world. (Edit: like you say, "appreciation" towards fathers is usually limited to financial support, which completely ignores the vast majority of what it means to be a father (and also marginalises full-time dads whose partner is the working parent))
