4@sun They are literally calculating all the rain that falls in a field as "water required to proceed beef". Without the cows, the water still falls and lands on the ground.
Does anything improve if you remove said cows from the field? The rain still falls, the water still seeps into the ground. Shitlibs are still retarded.

21@sun @BroDrillard @jeremiah It is. But see it also produces meat. And IMO that's a good and useful use of resources.
The business issue of adding numbers ?
The business issue of transferring information to one side of the world to another ?
Haven't we solved these already ?

1200 pound steer, you can expect a 740 – 770 pound carcass.
a steer drinks ~75 liters a day, and oldest at slaughter is going to be 2 years / 24 months
365 * 2 = 730 days
730 * 75 liters = 54,750
54,750 / 750 pounds = 73 liters for drinking water only
now let's do their feed
20 pounds grain mix per day is max, this is made of 30% oats 30% barley 40% corn
based on available data:
21 gallons / pound of corn = ~79 liters
290 gallons / pound of oats = 1,097 liters
~346 gallons / pound of barley = 1,310 liters
(1310 / 100) * 30 = 393 liters
(1097 / 100) * 30 = 329 liters
(79 / 100) * 40 = 31 liters
~ 753 liters / pound of grain mix
20 pounds per day * 753 liters = 15060 liters of water for feed inputs
15060 * 730 days of steer age = 10,993,800 liters
10,993,800 liters for all feed inputs / 750 pounds of beef = 14658 liters per pound
14658 feed + 73 liters of drinking water = 14731 liters per pound
seems pretty fucking close to 15,000 liters per pound of beef to me
@feld @BroDrillard @jeremiah @sun 99.5% of which is the growing of crops. Tell me, what is the negative environmental impact of using water to grow crops if sufficient water is already available?
at the rate it is used, fresh water is a non-renewable resource. land vertebrate biomass today is at ~7 times what it was naturally before human intervention (i.e. prior to global megafaunal extinction), and, to achieve that, aquifers globally are being drained more quickly than precipitation can refill them. it's not possible to just feed cows on grass in a field. you have to pump water and dig things from the ground to feed crops (alfalfa, soy, ...) for them
using water this way, you're taking the fraction of rainfall that was already absorbed and pumping it back to the surface for another chance to evaporate or run off. and the percentage that is absorbed takes nitrates (either from fertiliser directly or from animal poops) along with it, poisoning the aquifer and killing people who drink from it
the current number of humans on the planet is unsustainable, just humans alone outmass those historical megafauna, but the problem is made far worse by feeding them inefficiently, and eating vertebrates is one of the least efficient methods there is. designating more than 3/4 of all crops grown globally to growing baby animals into adults, with them all the while radiating energy away as heat, is just stupid when humans could eat those crops directly instead
@sun @BroDrillard
The point here is that a cow does not drink 3522 liters of water per day. (calculating 15,000L, average weight and lifespan of a beef cow)
@sun @BroDrillard The number is just to demonstrate the absurdity. I agree.
Then go talk to the jeets about them cows.
