From the above stats, a 2.3% change to USA meat consumption, up or down, has the same impact as a 100% change to data centre water consumption, up or down.
If I read the USDA stats correctly, US red meat and poultry production went up about 5.6% from Jan-Jun 2025 to Jan-Jun 2026, i.e. the increased production of meat led to an increase in water use that was twice as much as the water use of all the data centres combined.
It's not quite that simple. Most people who reduce/eliminate meat consumption are going to substitute something else rather than eat less, and what they substitute may be just as water intensive as the meat they replace.
For example, if a person's meat diet is virtually all chicken (reasonable given prices lately), substituting the chicken for almonds is a net neutral change. Almonds use every bit as much water as chickens do.
Granted, that may be an extreme example, as almonds are one of the more water-intensive crops, and chicken is one of the most water-efficient meats. There will likely be decent water savings in many cases, but at the very least, anything a person substitutes for their existing meat diet is going to use some water as well.
