Yeah this is mindboggling. It wouldn't have ever crossed her mind to tell her kid that they don't need oxygen canisters on this planet? I mean, what the dad said is good, as it opened the door to some more learning... but wow.
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.
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.
I mean... I know perfectly well that plants produce oxygen, but it never would've occurred to me that that was waht a child asking about oxygen tanks wanted to know.
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.
Right? This seems like a…strange problem to have. “Why don’t we need gas masks when we go outside?” “Why don’t we need to worry about rivers of lava?”
…because those aren’t problems on this planet. Lava stays underground unless there is an active eruption and the air outside isn’t toxic. Pretty simple.
A time traveler's survival guide. The vertical green bars are the only times in Earth's history with enough oxygen to breathe (hypoxia) and low enough to avoid oxygen toxicity (hyperoxia):
That blue bar is extremely pessimistic. Humans can survive pretty well with 15% oxygen, and do so in several places in the Andes mountains, China and India. I wouldn't recommend doing it without lengthy acclimatizing, especially not considering my last paragraph, but it's completely survivable by itself.
Humans also don't really have a problem with 25% oxygen, although that will definitely bring down the life expectancy.
On the other hand, note how those pointers talk about giant insects, megafauna and other scary things. Those are a much bigger problem than the air you're breathing.
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?
You don't get oxygen toxicity, even breathing pure oxygen, unless you're under significantly more pressure than atmospheric pressure...
So either this graphic is wrong/misleading, or the atmosphere was more than double current pressure for most of earth's history... Which I'm pretty skeptical of.
Yep. I was reading at a 6th grade level in 1st grade, and had advanced to university level comprehension by 5th grade. WTF was an "age appropriate book?"
I'm pretty sure that those people would have been incensed, if they knew that I chose TLotR as my 1st grade book report. (This was in 1985, so while there was an animated movie, it didn't cover the entire three books, so I had to read them.)
I'm extremely impressed that you were able to read and understand LotR at 7 years old. i read them at 15 and loved them, but definitely had trouble at the council of the elves etc
And they tell you to get whiskey or rum, not Coors.
Or a Coors. Who cares. It's alcohol.
Also how many whys does it take to get to the big bang and final we can't know before popping we need better instruments or math so difficult it's impossible for even mathematicians to pretend to make sense of besides 'maybe, the math works anyway.'
Almost everywhere…if all the men in your life are really that shitty it’s time to prioritize getting the fuck out of whatever community you’re stuck in.
yes, fytoplankton, but those are plants too. THey'll be extinct in +/-500 years because of the ocean acidification, which is a result of the sea absorbing CO2 from the atmosphere.
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))
Dude... just like.. think before you speak to a stranger on the internet. You assume. You assume I've never raised a child that wasn't mine in a relationship that lasted 10 years. You assume I didn't wake up 30 minutes early every morning to drive my exs' kid to school for 5 years. You assume I don't have my nieces and nephews over for sleep overs regularly. Mostly you assume that I don't take the "financial possibilities" of having a child into consideration. Just like shut the fuck up. I'm sorry, but be quiet. The adults are speaking and you don't know of what you speak. You spew, you throw up nonsense. Be quiet 🤫
Mostly, mostly you may assume I'm female. I'm a 40 y/o male that aches to have a child to love and raise. I yearn for the day when a child says "I love you dad" to me again. Cause it happened with my exs' child and it's like a hit from heroin, instantly addicted but in the best way possible
Or if you want to go full crash course, "For now, but that hasn't always been the case and might not be in another million years" and explain things like Oxygen Collapse/Great Oxygenation during the proterozoic when oxygen levels first shot up and killed off a ton of oxygen-hating things.
