Here's another resource describing the positive values of a plant-based diet. This is a short, easy read, still very informative but a bit less academic in style than the article from my previous post.

They illustrate the radical difference in land use between one kind of diet and the other with this graphic...

The world is running out of fresh water. A major cause of that is factory farming. But if we shifted to a plant-based diet...

@breadandcircuses I'm surprised by that graph, as tomatoes are HUGELY water intensive as a crop.

@ai6yr @breadandcircuses

214 litres of water per kilogram of tomato

Although that doesn't give the number of KCal for each.

Don't get me wrong, I'd prefer we stop murdering animals.

@ZikZak @breadandcircuses Oh yeah, the chart is valid (animals are hugely intensive on water usage and energy inputs, etc.), just surprised that "tomato" is there as the most water efficient thing.

@ai6yr @ZikZak @breadandcircuses

the picture is misleading.

It takes 15,000 liters of water to produce one kilo of beef.

Cocoa 27,000 liters

Roasted coffee 21,000 liters

pork 4,730 liters,

Poultry 4,000 liters

Nuts & millet 5,000 liters

Raw rice 3,470 liters

Vegetables and fruit such as carrots, potatoes and green salad are foods that require less water. All of them are under 250 liters per kilo.

I found these figures on several sites.

@Gehtso

What exactly do you find misleading about the picture? Those numbers seem consistent with what is shown.

Or are you saying that they could have chosen a better lower-bound veggie than tomato to further emphasize how costly cows and such are? (Which I agree with, though I'm not sure I'd say that causes the image to be "misleading".)

@FantasticalEconomics @Gehtso @ai6yr @ZikZak @breadandcircuses It'd be more useful to normalize by calories. 1 kg of water requires only 1 L, while 1 kg of butter has over 7000 Cal. Using the water numbers from the above chart, that leads to

Tomato: 1.18 L/Cal

Broccoli: 0.80

Peach: 2.34

Tofu: 3.03

Cheese: 0.79

Chicken: 1.97

Butter: 0.76

Pork: 2.53

Beef: 5.96

@jedbrown @FantasticalEconomics @Gehtso @ai6yr @ZikZak @breadandcircuses

Also if the butter, cheese, & beef are all coming from the same animals, how is the resource apportionment being made between each of those?

@HighlandLawyer

I don't think they do. Milk cows and beef cows are often not (never?) the same animals.

@FantasticalEconomics @jedbrown @Gehtso @ai6yr @ZikZak @breadandcircuses

That depends on the method of farming. Factory farming tends to strictly separate milk cattle from beef cattle, but traditional farming uses/used the same animals for both. Also even in that case, cheese & butter both come from the same milk cattle.

Therefore apportionment is a valuable detail to argue against factory farming of animals, not just for vegetarianism/veganism.

@HighlandLawyer

Fair. I'm sure all these numbers are from factory farms. Smallscale farming is likely to be different for all the numbers involved.

I'm still not sure you need to separate out cheese vs milk. Regardless of the proportion of raw milk going to the different end products, the water intensity for them doesn't change, and, unlike milk/meat, it can't be used for both.

@FantasticalEconomics @jedbrown @Gehtso @ai6yr @ZikZak @breadandcircuses

The original already separates out cheese & butter, which both come from the same milk. I'm assuming they're calculating the subsequent processing, though the difference is presumably taken by the resulting whey or buttermilk, which do have their own uses too.
