I argue that this is not a flaw. Our lungs likely did not evolve to filter out particles of this size because they did not exist until very recently relative to our species’ entire history. Therefore, this is not our body’s fault, only a shortcoming. The true blame goes to the producers of said particles.

At work, we are required to grind down the corrosion on the back of the wheel hub, every time we take a wheel off. This is how you’re supposed to do it, but most places don’t. Since they go so long without being cleaned, we usually get a large dust cloud of corrosion to breath in. I don’t know how, but for some reason they do not provide us with respirators to avoid breathing that in. So I guess I’ll just buy my own.

The oesophagus should be completely separate from the breathing pathway. We could then eat/drink and breathe at the same time, minimizing the risk of choking. The body should also have a backup method of assimilating oxygen in case the lungs become overly clogged up or compromised. Many of our bodily systems are far too vulnerable and in need of an upgrade. Of course cyborg bodies may one day be the better choice.

Just wait until you fine out what causes depression. Which is the pursit of fun and happiness resulting in 300 million depressed people, 240 million with anxiety and one of the top 20 causes for suicide. In other words, stop getting lost in fun and happiness and DO something to address the more serious matters before it's too late. Why destroy yourself losing yourself in drink and cigs to forget when pain improves people when it's face/confronted/accepted? I can understand it can be hard. It doesn't change the fact it's what works. If it's proven to work (it is) then avoiding pain, which results in drinking/smoking/being lazy, etc, is counter pdroductive. Ergo, do the productive thing. Face/confront even if afraid/in pain. I said "accept pain and fear". I didn't say "Chug down a bottle of booze". There's a difference. The complication is that even if facing/confronting evreything none physical (eg: always push for communication/honesty no matter how much you don't like it), it can get confused with "Take those drugs" or "Keep drinking". Accepting everything doesn't mean "chase" everything. Focus. Organize. Consider the long term affects of burgers and sausages. etc. The only thiing to always be chased for is "answers". Knowledge. Learning. Let the rest write itself. Question everything. Always stand your ground. Don't live in the middle of a city where there's a lot of fumes from cars (seriously, that's a big factor). Cities are death traps really. I do the smart thing and live on the side near a large park next to many trees with low rent (yea, you an do that). Imagine how clean the air is here. Control the mind. Control the body. We are what we repeatedly do. It's a matter of habits. Control the habits. Control your life. Plan. Organize. Act. Communicate. Plan. Organize. Act. Communicate. Remain consistent. Be persistent. Pushed. Struggle. Learn. Push. Adapt. Learn. Treat it like Dark Souls. It's a boss push you down until you keep trying enough to overcome (and please do that with close range instead of range spam if you play the game). Do it with something you can work with first. Push yourself. Do it with something else. Push yourself. What you learned from games you can transfer to other real events. Push yourself. I think I made my point here. Struggling and breaking is part of the process. Those that keep going learn to get through it.

Might have some long term effects which shorten old age, but that's still impressive. Don't underestmiate the determination of anything that acts of its own accord. It can be a person. An ant. A cell. It can even be a tree. Not a rock though. Rocks have no biological mass. Technically there's atoms, which are kinda like bacteria in some ways, so technically a rock could count. Hell, it's been around in the same form for, wow, that long. So yea. Evolution to the point that it works well enough that it doesn't need to adapt? Well, now I'm not sure what to think when it comes to rocks. This could indicate being static and not adapting at all is peak evolution. On the one hand, around that long. On the other hand, life would be very dull. Imagine never doing anything at all. Would it be worth being a rock and never doing anything until reduced to sand? Ok, so a rock kinda does adapt in a way. Becuase it's turned to sand. What happens after that? Huh. That's all I got. Didn't think I'd give that much thought to rocks.

Do any of the natural defenses you talk about happen when you breathe through your mouth? If not would that mean particles entering though your mouth have unrestricted access to your lungs? Thanks :)

[@matthewmullier]

While reducing your personal emissions is an important step in reaching net zero, it is very important to put this into the broader context. The term 'carbon footprint' was originally coined by BP to distract from the fact that it is corporations, not individuals that account for the overwhelming majority of carbon emissions. I am disappointed that a clearly well researched and put together video failed to include the necessary context when talking about the videos sponsor. Organisations like wren can often do more harm than good by emphasising individual change over systemic change and promoting poorly evidenced carbon offsetting initiatives. I think it is essential when talking about individual climate action that it comes alongside promoting collective and government action as we cannot solve climate change individually

The video doesnt know like who made the video. Base off internet google wannabe doctor.

[@Warriormon87]

This is the single most compelling video about cleaning up air emissions. Climate change constitutes a 1 degree increase in average global temperatures over the last 50 years. Not a crisis level of increase. Temperatures change more than that from one day to next. Most environmental problems we face are misattributed to climate when they are actually caused by something else: • Polar bears (Hunting. Now that hunting has stopped polar bear populations are better than ever.) • Great Barrier Reef (explosive fishing, dumping wastes. Combined with a low in the natural cycles of coral. The cycle natural cycle has come around and the reef is now at an all time high.) • Wildfires in California (they are drinking the Colorado river dry, without evaporation from the river it is creating a drought. To fix the over consumption they are implementing anti-evaporation tech, making the problem even worse.) • icebergs melting (this isn't a problem. Icebergs melt and refreeze every year, arctic life is literally dependent on this cycle. The overall max and min sizes aren't decreasing. The problem is people see dramtic pictures of icebergs breaking off and think that something that big breaking must be a significant event, when it actually happens constantly throughout each year.) But this video shows how the increase in polution particles adversely effects our health.

The most fatal flaw is the inability of our lungs to fully heal once the microarchitecture is disrupted. Inflammation can easily lead to ARDS which lowers the surface area to such an extent that sufficient gas exchange is impossible.

[@VinaySingh-jm8iw]

I'm confused about the sizes. I googled average air molecules sizes and found "The molecular sizes of oxygen, nitrogen, and argon are 0.299, 0.305, and 0.363 nanometers (nm)". If the smallest particles on your chart at 2:30 is 0.1μm (100nm), how would they richochet off molecules 1/300th their size?

[@Aereto]

The answer is simple: air itself is not still. Respiration and the fact that the air is close to body temperature means that air is constantly moving, and its has mass, so particulates lighter than air are most affected by air's own momentum. The only way air to stay still is to be extremely cold.

[@ianjackson9852]

It’s part of something called Brownian motion, where large particles move somewhat randomly by bouncing off of a massive crowd of much smaller particles.

[@caracalfloppa4997]

Those molecules are moving really damn fast. Imagine getting hit by a constant barrage of tennis balls going 800 MPH. That's roughly the kind of forces we're dealing with.

[@Warriormon87]

Yeah. Wren is not actually helpful for the environment. Other than them planting tress trees everything else is just politics and lobbying. Powerful politicians have invested in elecreic cars with the plan that they can convince people that driving them saves the environment. But electric cars use electricity and that that power means pollution (unless yours is being supplied by a nuclear power plant) even wind and solar need supplementary coal plants.

[@Warriormon87]

Wren is more about getting peoppe to buy into a world order where you can monetize "good for the planet." Many such credit systems already swap in supporting certain polics as granting credit, so you can be horrible for the environment but tell people you're good for the environment by support the credit organizer's political party.
