Why is Ebola getting out of control, if prevention is so simple? | I agree with /u/alexwojtak - there is a huge cultural and education barrier than most people can't even comprehend. Also, there is essentially no medical or logistical infrastructure in much of Africa. In order to prevent transmission, the people responding need personal protective equipment and other medical supplies.... |
Why is it that it's commonly accepted that yellow teeth indicate unhealthy teeth, while I keep hearing that yellow teeth is actually a sign that your enamel is strong/thick? | First thing I noticed coming to the us was that bleaching is the thing. In Europe it wasn't. English actor usually have unbleached teeth. At least that's what it looks like.You can try rinsing with water after drinking coffee, tea or juice. Not sure how much that helps tho.Teeth vary in shade. Some people have naturall... |
Why do movies still display with a letterbox when today's televisions are built for that size? | What's even worse, is the movies that are widescreen, but will show on-screen with the box all the way around it! I still haven't figured this out. |
How to get to the Moon? | As far as the fuel goes they use either solid rocket fuel or liquid hydrogen fuel. If they use liquid hydrogen then they have separate tanks for liquid oxygen so they can burn in space. Thrust in space works basically like if you throw something backwards then you will be pushed forward because if conservation of momen... |
How close are we to curing cancer? | Cancer turns out to be lots of different diseases, not just one. On some, we've done amazingly well. Some forms of breast cancer, for instance, are not very likely to kill you any more. On others, there's not much we can do. Not close. ", 'How close we are to curing car crashes? We're not. Without a groundbreaking omni... |
Why do people that bitch get rewarded free stuff or discounted orders and people that are patient get nothing? | As someone who works in retail: Free/discounted stuff doesn't come out of my pocket. Sometimes it's easier to just give them what they want to make them go away instead of arguing with them. |
Isn't searching for past possible Nazi war criminals, who are well into their 90's, a big waste of money and time? | Is it a waste? Technically, sure. Its more about closure. The people searching are trying to close an open wound that's been festering for decades. Even if its only symbolic, it still means an end to that chapter. |
Why do so many racing video games look almost photo realistic when games from other genres don't as much? | In addition, with all the models whizzing past you probably aren't gonna be able to get a really good look at anything, except your car which is probably just a high-poly model", 'All the other answers, plus one of the biggest "tells" of CGI is that things look too shiny, because the way light behaves is really complex... |
The difference between torrenting and watching a movie (a la youtube) on some illegal site? | If you watch a movie from a streaming site, you connect to one particular server that serves the movie to your computer -- specifically, to the viewing application that pipes it to your screen. The pieces of the movie have to arrive in order and faster than real time. If you torrent, you get random pieces of the movie ... |
why doesn't the UN flag include Antarctica? | The UN flag or UN symbol was originally a representation of the members of the UN. As the UN grew in membership the symbol morphed into the one they use on the flags today.Antarctica is not really a 'Nation' as it is not 'owned' by anyone. It is truly a multinational place with an agreement called the 'Antarctic Treaty... |
Why are teenagers so certain in their beliefs? | [The less life experience you have, the more certain you'll be you've experienced it all.] |
Why fax machines are still used? The technology is dated and we have better options today. | Bureaucracy loves to leave a paper trail, hard copies of documents are more secure and can be used to authenticate certain things, making them preferable over an email or something. Since you can't really get a digital document legally certified without printing it.They are ubiquitous, cheap, and fairly easy to use. Fo... |
what is the point of disallowing viewers from certain countries to watch YouTube vids? | This is due to copyright laws. Companies have to comply with general national law of the country and, if they want to show their content elsewhere, regional laws everywhere they broadcast. Sometimes they are either not big enough or simply don't care to deal with this. Some countries also refuse to play content by some... |
Why do we, as humans, love having sex but get grossed out when we see/hear other people having sex? | I'm not thoroughly informed regarding the finer details, but it's basically because sexual excitation has a kind of inhibiting effect over the parts of your brain that tell you that something is gross/disgusting. I remember reading a study a while ago, I'll look for it and post back. EDIT: [Here's the article.]", 'My g... |
Why would anyone oppose an improvement of the relationship between the U.S. and Cuba? | Cuban exiles are a very influential minority in the US, especially in Gulf states like Florida. They were killed or forced to flee by Castro's regime, so they have an interest in trying to bring down the dictatorship. |
What is the Speed of a Photon as it Gets Reflected by a Mirror? | You've partially answered your own question - photons move at c. What you're missing is that they're not the same photon. When light hits the mirror, the photons are absorbed. The reflection is other photons being emitted, travelling at c. |
Why is the % midwife births in the United States so low in comparison to the rest of the world? | Most Americans that I've met know about midwives. However, the explanation I've gotten multiple times is that if anything goes wrong during the birthing process, it's better to have a doctor around. Most soon to be parents want to minimise risk and thus end up going to the doctor instead. |
Why does closing your eyes when you are tired feel so good? | i assume that your brain waves , start to lower from all alpha to mixed alpha and whatever's lower. |
If I always feel mentally and physically better after exercising, why do I still avoid it like a whiny toddler? | I think it is a matter of motivating yourself further. [At this url,] _URL_0_ lists motivational factors which are not situation specific. > achievement, advancement, autonomy, personal growth, recognition, responsibility, and the work itself. Maybe you've hit some points but not enough, so it's like a chore that you w... |
Why women's nipples are censored and NSWF but men's aren't? | Because our society has sexualised women's breasts to an extend where we can't even show something as natural as breastfeeding. |
Why is it that out of all the senses, smell is the most effective in triggering memories, especially very early memories? | because the pathways through our sensory systems in our brain is much MUCH simpler for smell than it is for the other senses. It basically skips a big step and so it's easily associated with memories or events. Its much more a part of our experience than it is a sensory stimuli associated with it. I hope this is ELI5 |
Why does lightning strike in a zigzag rather than a straight bolt? | Lightning takes the fastest route to get to the bottom, not the closest. Even though the closest distance between two points is a straight line, if there's a pillar in the middle of the two points then that line won't get anywhere. Instead, the lightning just jumps from molecule to molecule. Theoretically, it could tra... |
Why can't we sneeze while we're asleep? | Fact: most people also can't fart when they're asleep. They'll wake up temporarily for a few seconds to fart, and then immediately drift back to sleep within like less than a minute. I imagine the sneezing process is also working by a similar concept. Some processes require consciousness to activate, I guess, for a tru... |
why don't international sports players (ie. Lionel Messi) represent their countries at the Olympic Games? | You can have 3 players over 21 in the team and every one else has to be under. Some teams don't like there senior players playing in pre season due to risk of injury and so the Olympic manager tends to pick others. |
Why do any Americans who are not white, rich, and male vote Republican? | You underestimate how many voters have no knowledge of the policies of the people they vote for. You also underestimate the amount of advertisement and gerrymandering to counteract this exact thing you're talking about. Republicans are super good at getting people to vote against their own interests by convincing them ... |
How do they shut down entire cities to record action movies? | They pay for a permit to shut down one area at a time. They don't shut down an entire city. Weird trivia fact. In terminator 2 where Arnold rides the motorcycle off the bridge into the drainage ditch was finished filming 5 minutes before their permit ran out. The cops were waiting just off screen to shut down productio... |
how do Uhaul and car rental companies get their cars and trucks back when they are dropped off in different states or cities? | Ideally, there is enough balance that a return trip brings the vehicle back. That's the reason you see so many out of state license plates in a lot of rental places, they just keep the car and hope another car will make it back. If not, the next option is to pay customers to do it. If you want a one way rental from Atl... |
why is it ok for a woman to take an abortion pill, but if a woman's significant other tricks her into taking the pill it is considered murder? | Because it is a part of the mother's body at that point. It's like asking why it is a crime for me to gouge out *your* kidney, but why I would be allowed to donate my *own* kidney. |
Overthinking and rumination - the feeling of being 'stuck inside your head.' | Linked to this can anyone tell me why my brain sometimes just won't let me 'escape'? Sometimes I feel like I'm not in control of my brain? Not in the sense of doing things I shouldn't be doing , just more like I feel like I want to pull myself out of a depression but my brain seems 'stuck'. Sorry if I didn't explain my... |
What causes babies to go from happy as can be one minute, to bawling their eyes out the next for seemingly no reason? | Babies don't have a middle ground, it's all extreme, black and white thinking, pure absolute emotion, they don't remember this 'split mind' when they get older |
How does jamming a door with a chair actually keep the door jammed? | The handle can't be turned because the chair is pushing against it from underneath. It can't be pushed because the chair is jammed between door and floor, blocking all movement. |
What is a 'sun fade' outage caused by the 'physics of the sun' jamming satellite receivers? My local TV station cited this as the reason the station went off-air for a short time. | Simply put the sun is directly in a line with the satellite and the receiving dish. The sun transmits enough energy at the frequency used by the TV program provider to overwhelm the satellite's signal. These outages are completely predictable and most TV stations plan accordingly by switching to another satellite for t... |
How did Japan go from basically America's worst enemy to a cultural and technological powerhouse that took over the US? | After World War 2 the allies helped rebuild the infrastructures of Japan and Germany which led to those two countries having a much easier job recovering and becoming economic powerhouses. Whereas, in the US our infrastructure is rather old and probably hasn't ever had a major refit, so we lag a little behind . The sem... |
What lead to Japan and Germany becoming allies in WW2? | Japan wanted to be a world power, they had few little battles with Russia in WWI, but were mostly ignored by Europe and the US. Japan was on the winning side of WWI, but didn't have much say in the treaties ending it, which is sorta how they met Germany. From there, it's basically because Japan and Germany are so far r... |
In a time of war, how are the Geneva Convention codes enforced? | The possibility of losing the war. It's not just Geneva. There's the Hague Convention, treaties, etc. If you lose break these conventions and treaties the other country isn't going to be happy. Ask the Germans and Japanese what happened after WW2. They got hanged and shot. |
Why are all the Olympics money losers except Los Angeles in 1984? What did they do that all other host cities refuse or were unable to do? | Los Angeles was able to reuse a lot of its previous Olympic infrastructure. As well as large stadiums the Olympics requires a number of speciality facilities for certain events. An equestrian centre for example is unlikely to attract a lot of visitors once the Olympics is over. This has been a particular problem for bo... |
Why is it socially acceptable to eat donuts for breakfast, but not ice cream? | This is something of a shaky and potted history but in roughly 18th Century Europe, the entire structure of the day was different and what we would now eat at breakfast time would be a high-carbohydrate snack between the work you did in the early morning and the work you did in the early afternoon, thus it made sense t... |
Why is Obama disliked in the USA? | Because he's the president.We have become an aggressively hyper-polarized nation in terms of politics, so half the nation will hate the president at any given time. |
Why are most euro coins still in the country where they were minted when the currency has had so many years to circulate in the eurozone? | People just don't use coins that much. It's the kind of thing you dump out of your pocket at the end of the day . If you're travelling internationally you might dump it in a donation box rather than deal with the metal detector.Never been to Belgium? Only one in three coins in my wallet are Belgian. |
How are movies edited to be in 3D when they are't originally filmed in 3D? | I'm not 100% sure of the process but I imagine basically some people manually identify objects and sets their depth and then some software applies the appropriate polarization to the film. This is why post-processed 3D files generally have limited depth to a few layers, usually the actors, a few important objects and t... |
How do fire detectives discover the cause of a fire when everything is burnt and destroyed | I imagine its like a gradient. What's most burnt in the centre > less burnt around the edges. |
Why are speed cameras always accompanied by big signs that let motorists know they're there? | If there is a sign they slow down, if they don't know about the camera they just keep on driving too fast. It's about preventing an accident, not about punishing speeders |
Why is the stock market doing so well when the U.S economy is in a recession? | The economy isn't in a recession, it is recovering *according* to figures. Depending on what happens on the global markets, you're grandfather might not be too far off that the stock market is bloated. The reason that investors are investing in stocks is because Federal interest-rates are way low, which means that mone... |
If it's illegal to deface American currency, how are those machines that flatten pennies and put a design on them legal? | Defacing currency isn't illegal. What's illegal is defacing currency *with the intent of committing fraud*. For instance, doctoring a $10 to look like a $100 bill. |
How do microphone "Pop Filters" work? | A well-built microphone is Very sensitive to sound waves, and the metal mesh around it is for physical protection more than sound filtration. The 'fabric' is actually a foam; like a sponge. It's not necessary for microphones further than a foot away, but speaking into a naked microphone close to your mouth will yield l... |
Why are there no primates in North America? | About 40 million years ago, the Simiiformes infraorder split into parvorders Platyrrhini and Catarrhini .[9] The individuals whose descendents would become Platyrrhini are currently conjectured to have migrated to South America either on a raft of vegetation or via a land bridge. There are two possible rafting routes, ... |
Why do American employers give such a small amount of paid vacation time? | Why, because there is no law saying they must do otherwise. My understanding is that long vacations in Europe are mandated by law. There are exceptions -- in highly competitive tech companies you'll sometimes see excellent vacation policies. |
How would traffic be different if all cars were self driving? | In addition to the effects everyone has mentioned about how the cars would behave on the road, there's also the effect on how many cars might be on the road in the first place. The traffic might be worse, if everyone in the city just tells their car to do some laps of the block or go back home instead of paying for par... |
How can you be an Anarchist and a Communist? | > I know that Anarchy is the absence of government Most people who take anarchy beyond nihilism see it as the absence of *involuntary* government. Meaning you choose to be part of it and adhere to its rules, and if you don't like it, you are free to leave. In that context, communism can coexist with anarchism quite rea... |
What's the difference between a well-crafted interaction website for mobile devices and an app? | The app can spy on personal data that doesn't have to be input directly to the app. Went through my phone and disabled some if the social apps I had and found out they had permission to make calls, send texts, read contacts, etc. |
How do some people live unhealthy life styles but are still good at working out/exercising/pt? | Just because they are smoking, drinking, and eating fast food doesn't mean they aren't putting in the work to stay fit too. The body is capable of handling far more than the mind thinks. Also some people have good genetics. |
Why do old Chinese people act uncivilly on buses? | As it has already been covered, it's a cultural thing. Their upbringing is basically to be cutthroat fucking douche bags! Edit: so, uh, thanks kind stranger for the random gilding! I just noticed every comment is gilded!", 'Theory 1 is correct. This idea of you have to be ahead of everybody else is ingrained throughout... |
Why is zero often placed after nine instead of before one? | People don't count from zero to nine. Also, the number one is considered the first integer . |
why is FIFA so against using technology in football? | Because the game was designed to be judged at full speed. Judging fouls and penalties is different when done at slow motion. Player intentions get skewed and that's a big part of the ref's decision. Imagine how every hand ball and every push off would look intentional in slow motion replay. The goal line technology is ... |
Just bought my first home. What effect will that have on tax returns? | We bought a house in Oregon this time last year but only had to pay one months mortgage payment. Our tax return wasn't much since we didn't pay much, I expect this next time to be more since we've actually paid a whole year. It's based on the interest you pay. |
Why is scary or dangerous stuff intriguing? | I don't have a good answer but I suspect it has something to do with triggering the panic response and us enjoying the emotional rush that gives us. On a related note, I find it fascinating that the mere sight of a shark or snake excites me and gives me a feeling of dread even though I have never been bit by either and... |
In motoGP how do they get there bikes at such angle without the bike actually slipping out from underneath them? | For a slightly more ELI5 version , and not taking away from the stuff about tire design or gyroscopic effects that others have posted: In the normal course of things that aren't accelerating very fast, we feel gravity pointing straight down. If we're accelerating, then we feel an additional force - like when you feel h... |
Why can't we go to venus if it's so close to us? | Incredible atmospheric pressure, high enough surface temperatures to melt several types of metal, dangerously high wind speeds, sulfuric acid rain that boils away before it even reaches the ground, the clouds are mostly made of said boiled sulfuric acid, and it may or may not have surface volcanic activity. Take your p... |
How can drug companies be sure that new drugs won't have serious side effects years later? | Short answer: They don't. Slightly longer answer: During testing, they are supposed to carefully monitor for things that could eventually cause side effects. [Sometimes they miss things.] |
Why do dogs lick human faces to show affection ? | My understanding is that they're not showing affection, they're hoping you'll spit up food. At least, that's how dogs often react to that behavior in the wild. Hard to say if domestic dogs are doing the same thing, doing something different, of a combination. |
How can an abortion be "reversed" and why did Arizona pass a law making doctors say that? | The idea is that a chemical abortion is a two stage process where two pills are taken. Conceptually not taking the second pill can result in giving birth normally. An anti-abortion doctor has anecdotal accounts of an injection which, along with not completing the abortion pills, he claims will help to save the pregnanc... |
Why does gasoline pricing produce such acute price sensitivity in consumers, despite the negligible differences in totals over filling an entire tank? | In regards to why consumers are concerned at a macroeconomic level, imagine the average American family with two cars - a van and a truck - that's about 45 gallons of gas that needs to be filled roughly every week. Over the past three years, the lowest average price of gas has been about $1.70 and the highest average p... |
Why does the US get cheaper gas prices than Canada? | One part of the reason is taxes: Let's compare fuel taxes levied by similar provinces in Canada to states in the U.S. per U.S. gallon of gas. Ontario: $1.07 minimum New York: 74.8 cents Alberta : 75.7 centsNorth Dakota : 47.4 cents If you were living in Alberta you could save a lot of money by just going across the bor... |
If obesity is 'the most serious public health issue of the 21st century', then why isn't it addressed by any of the electoral candidates in the current U.S. electoral campaign process? | They do, but it's not anything that drives up votes for the party, so it's not that important to them. I think personally that Americans don't want to be told what to eat and how to live this aspect of their lives _URL_0_ |
How can we shape C4 to explode in a certain direction but we can’t with nuclear explosions? | you absolutely can shape charge a nuke. you just need to put something on one side that'll have enough mass and strength to absorb the blast concussion and the temperature. like .say about a mountain's worth of mass.This is from Atomic Rockets, in the section called "conventional weapons" to give you some context for t... |
How does my car know if it is icy outside? | I highly doubt your car has onboard sensors to tell if it's icy. Instead, it's either temperature based, or fed through your satellite navigation system.Once the thermometer senses that the temp outside is 37 degrees your car will warn you that it is potentially icy outside.My car will display ICE POSSIABLE on the disp... |
If police can seize a house because a child in that house is caught with drugs, why couldn't the U.S. government seize Wells Fargo when they got caught laundering money for drug cartels? | > ELI5: If police can seize a house because a child in that house is caught with drugs, why couldn't the U.S. government seize Wells Fargo when they got caught laundering money for drug cartels? Technically they can. Although if they do it would severely disrupt the economy so instead they agree to pay fines. In a link... |
why did you need to wait for the "green light" on old cameras to use the flash? What was taking so long ? | The flash in an old handheld camera was a bulb called a flashtube. Basically, the camera's battery would charge up a capacitor to a very high voltage Then the capacitor discharges, creating a spark, which causes a very bright light for a very short period of time. So when you saw the green light, you were waiting for t... |
Why is there sand at the beach? | because if there wasn't sand there it wouldn't be a beach, it would just be a coastline. sand forms from big rocks banging against each other to make little rocks which bang against each other to make coarse pebbles which bang against each other to make fine pebbles which bang against each other to make sand.The real q... |
When I stub my toe, why is the pain delayed for a second before it really kicks in? | You experience pain way slower than the actual physical process that's going on because of the slower connection. When you put your hand on a hot stove, you will immediately feel that it's hot but the pain comes later because of the slower connection to the central nerve system. |
Why is it so hard for someone to kill a tyrant/dictator/etc from within their own government? | Why doesn't a dictator commit suicide? Because they're enjoying their position. Those in the higher echelons of a dictators society are generally doing very well for themselves also. It's also pretty much impossible that someone would survive long even if they managed to kill a dictator. Loyal guards and all that are s... |
How were people in the past able to create fountains shooting upward without the use of electricity? | They used gravity and fluid dynamics. If a water source is at a higher elevation, it will have a certain amount of pressure to it depending on the distance the water travels and the difference in elevation. Also, when a fluid is flowing through a pipe and that pipe's diameter is reduced, the pressure of the fluid is in... |
How is it possible for tiny SD cards to have 200GB storage? How do they create more storage space on something that small? | Short answer is Moore's Law. Technology continues to scale down allowing for more storage/circuits in the same physical space. We are basically making the space that holds each bit smaller with process enhancements and new technology. |
Why do credit card scanners have to ask "credit or debit" instead of figuring it out automatically from your card? | You can run a debit card as a credit card and the money will still come off of it but it will take a bit longer, like a day or two. That's all I've seen as the difference. Oh and no cash back options. As to why, I have no idea. |
When my cat sits on my touch lamp, i can use his nose as an on/off button. How does this work? | The cats tush is all fuzzy making no connection. When you boop it on the nose it's butt puckers making the connection |
When I get a headache, what is actually hurting? Is it my skull, my brain, tissue? What?? | Headaches are pretty complicated, and the way they work isn't fully understood yet. Sometimes part of your head hurts. Your eyes, ears and your sinuses actually go pretty far into your head. If your sinuses get backed up from an infection, or allergies it can cause pressure issues inside your ears, against your eyes, o... |
Are there mindsets that manifest themselves and create mental illnesses? | I read a book called Learned Optimism by Martin E. P. Seligman. In this book he talks about his research in how pessimism can lead to depression, especially if you also have the type of personality that ~~rummages~~ ruminate . He talks about how most people will go through depressed periods in their lives, but pessimis... |
How does Reddit stop bots from signing up without a captcha at the sign-up page? | They don't. They combat spam accounts by letting them sign-up, but then shadow-ban them when they're detected as a spam account. Since you can't actually tell when you're shadow-banned, the spam account would just keep posting even though nobody can see them. |
How hard would it be for a human to change away from a 24 hour day schedule (for instance living on a planet that had 30 hour days) | I feel like it wouldn't be too hard if there was still a circadian light/night rhythm. It's only an extra four hours, and if there was sun and night like we have now, I think the body would adjust quite well. Just like it adjusts when the nights get shorter in summer. Or longer in winter.I 've heard of a 28 hour \'Prog... |

Why does 70°(F) air feel great, but 70° water feel incredibly cold? | When we experience temperature, we're really experiencing the rate of temperature change touching an insulator like a book feels warmer than touching a block of metal the exact same temperature! Here's a good link that explains it fairly well: _URL_0_ Edit: Brain fart word choice |
If I send a heater into space and turn it on, where does the energy form the heater go? | It goes into space as infrared radiation - which is just another term for light that's below the red end of thr visible spectrum. |

How is the meat and chicken industry meeting the global food requirement without wiping out farm animal populations? | They grow large numbers of animals in small spaces, bringing in grain by truck for them to eat. A large percentage of the world's grain production is fed to meat animals. |
Why does WLAN know my exact location but LAN doesnt? | When companies like Google drive around cars for street mapping / photo purposes, they also collect information about nearby Wi-Fi Access Points. This information not only includes the SSID , but also the MAC address that uniquely identifies each router . These companies collect and store this information in massive da... |
What is the significance of Sean Hannity being Michael Cohen's client? | It's a huge violation of journalistic ethics for him to have been commenting on the raid of Cohen's office without disclosing that he has a stake in the matter, being a client of Cohen. He's been lying by omission to his viewers for the last week by presenting his attack on the Special Counsel and the SDNY as the opini... |
How beer can go bad but not liquer | The alcohol in most beer is a low enough percentage that bad stuff can grow in it. A few beers, often called barleywines, are strong enough that they can't go bad either. |
Why does tickling myself not make me laugh? | One theory is that being ticklish may be a warning system. An unexpected touch may be a threat and it activates your sympathetic nervous system to get you to protect yourself. It's noteworthy that many ticklish areas are also vulnerable areas. An anticipated touch like when you try to do it yourself doesn't activate th... |
Has the physiological damage caused by trauma been the same through out history? | Yeah, no, it wasn't nearly as common as you seem to think. Why do you think things like the Salem Witch Trials or the Spanish Inquisition are such a big deal in history books a century later? People only get tortured and raped by every other guy on the street in the movies. The fact of the matter is, by the time it got... |
Why is all the CO2 in the atmosphere bad? Shouldn't it promote more plantlife, since they use CO2 and put out Oxygen? | When Oxygen and CO2 are in proper balance, it's fine. Digging up millions of years old carbon, in the form of fossil fuels, and burning it upsets the balance, producing more carbon dioxide than the existing plants can handle. |
Why does it seem like there are way more guys on the Internet than girls? | The internet is very, very good at separating out people by their particular interests. Guys' interests and girls' interests have some overlap, but there are great big ranges that *don't* overlap. If you're a guy, the parts of the internet that interest you the most will usually be parts that also interest other guys .... |

- Communism, and the general dislike/fear of it in the US? | just hang out in /r/debateacommunist for awhile and you'll get a good understanding of it. communism and marxism get asked about here every other day and the answers are consistently garbage.The "fear" was simply a very well designed propaganda campaign designed to protect those who have lots of money from those who do... |
Can someone explain how water gets recycled? (Ex: we drink water, pee it out, then....)? | In cities with treatment plants and sewers and whatnot, it's a bit different, but in the country, it's basically: Drink water. Pee water.
