Like the notion that animals don't drink water, and that we don't absorb water unless it's organic. Can't imagine how someone could not be aware of animals in the wild going to water holes to risk their life with crocodiles to get water... Or someone dying from lack of water not being saved by a drink of non organic water.
The hervibores mainly do that in the summer when it's hot and they sweat a lot, and throughout the year when much of the plants they've eaten were dry rather than fresh, so they need water to compensate.
The carnivores are there to combat the heat, to drink some water because they only catch prey once a week or less, and also to wait for the herbivores that will inevitably come by.
If you eat lots of dry or partially dehydrated foods, of course you will need to drink plenty of water. If you eat mostly fresh foods, there is little or no need for water most of the time. If you haven't eaten anything in days, then of course you will need to drink water.
The whole idea that we need 8 glasses of water a day, 2 liters a day, or whatever other standard like that is a misnomer. Yes, we need about that much "water", because that's the water content that is included in the fresh foods that we consume daily. If you remove the water from the foods, then yes, you have to add it back in, although it won't be the same. Mostly all fresh foods are 60 to 90% water by content.
Nobody said we don't absorb non organic water, rather what we think is that this water leeches minerals from the body.
