Our waterways are becoming more and more polluted due to PFAS, plastics, medicines, drugs, and new chemicals made by companies that just hand over the responsibility of cleaning to plants paid for by public moneys. Detecting the different chemicals and filtering them out if getting harder and harder. Could the simple solution of heating up past a point where even PFAS/forever chemicals decomposes (400C for PFAS, 500C to be more sure about other stuff) be alright?
How the hell do people use that much water? Are they including water consumption needed for the products we use or? Let’s say a flush is 8L and the average person flushes 5 times a day, that’s 40L. The average person needs about 2L of water a day. Let’s say an average shower is 100L. Cleaning dishes at worst is probably like 20L per person without a dishwasher. That’s like 160L of water per day and I feel like most of those were over-estimates. How did they get to that number?
Dishwashing is a significant underestimate here, and don’t forget hand-washing (before/after bathroom, food, cleaning…).
Plus you missed outdoor and gardening, which would help explain why the Land of the
FreeLawns uses more than anybody else.Ok yeah the second part makes sense, but for the first part I was calculating it based on hand washing, dishwashers would be way less since you have to split the usage per person in the household, which holds for hand washing as well. Idk for other people but when I’m alone I use the dishwasher probably every 3-4th day and for handwashing I’d say 20L is realistic, double it maybe but still isn’t that much.
They eat meat.
They use AI.
How much water do you believe AI consumes? The 31 billion land animals we keep in captivity and the crops we grow to feed them dwarf most human water consumption.

That’s a lot, but by some back of the envelope math I calculated that American consumption of cheese alone uses four times that amount in a year.
Based on this, 4 oz of cheese uses 450 liters of water. https://foodprint.org/blog/dairy-water-footprint/
Based on this, the average American consumes 41 lbs of cheese per year. Each lb of cheese uses 1800 liters of water per the above. https://www.statista.com/statistics/183785/per-capita-consumption-of-cheese-in-the-us-since-2000/
That means that each US citizen uses 73,800 liters of water per year on cheese alone.
Multiply that by 340E6, the US population, you get 25 trillion liters of water per year. That’s 25 billion cubic meters of water a year.
Not that AI is environmentally friendly by any stretch, but dairy is the equivalent of like, a dozen AI industries all stacked on top of each other. Feel free to check my math and correct me as needed.
For the record, dairy production and consumption has been around for almost all of human civilization. It had time to really embed itself in society, and it served a very real, practical purpose. It kept people alive.
The AI hype has only being going for like a decade and shows no signs of slowing down. Those numbere are literally rookie numbers.
Perhaps there have been times of famine where it kept people alive, but today and throughout most of human history, it’s simply killing people. Something like eight of the top ten causes of human death are consequences of diet. The leading cause of all human death goes away completely without consumption of a class of products that includes all dairy. Dairy is not healthy to consume, it is harmful.
I always find those kinds of numbers difficult because they include rain water in that estimation.
What percentage of the 450 liters of water comes from those different sources? How impactful is a green water footprint vs a blue water footprint vs a gray water footprint? If the 120g of cheese were made from 100% blue water, that would definitely be problematic. But if it were 100% green water, that would most likely be less of an issue.
Next, you have to consider how the water comes into the calculation. Is it just considering the water for feed crops of the water that the cow itself consumes? And if it’s feed crops, the type is also important. Some feed is simply the byproduct of crops that are used for human consumption e.g maize only has maybe 10% of its biomass for human consumption. Would simply throwing away the other 90% be considered wasteful or useful? And how does that factor into the water calculation?
And a final point regarding feed, is what kind of feed it is and where it’s grown. Feed may not only be byproduct of human comestible crops but also crops that cannot be consumed by humans at all, and they can also grown in places where human comestible crops cannot be grown.
Now you have to compare that water for server farms. I have little knowledge thereof, but my guess is that they don’t wait for rain to cool their servers and it probably is more blue water than not. It maybe as entangled and complicated as the source of water for cheese, I don’t know.
My point is, it’s not an apples to apples comparison. Water consumption doesn’t always equal water consumption. To drive the point home, would you consider the water required to raise fish in a landlocked country the same as that of a coastal country?
What is your actual point? “Don’t worry about water consumption?”
Yeah but it says “at home” and gives recommendations how you personally can reduce water consumption (like more efficient taps or showerheads), which makes me believe that it’s not your entire direct and indirect water consumption (which realistically isn’t even relevant for the argument since the water used for crops isn’t gonna be getting treated anyway)
The estimations for water required to make meat even include rainwater. As if cows are out standing in the field collecting water through their hooves or something.
The crops are literally standing in a field collecting water through their roots. Sometimes it comes from rain, but an ever-increasing share comes from irrigation. One way or another, that water has to be accounted for. Rainfall is a limited resource in agriculture, like any other source of water. Even entire rivers are often 100% consumed by agriculture.
