For some numbers:

One graph even has California’s animal feed water usage so large it actually goes off the chart at 15.2 million acre-feet of water (it is distorted to make it fit as it notes). For some comparison, the blue water usage of animal feed is larger than all of almonds water usage of ~2 million acre-feet of water

EDIT 2:

Also worth noting is that per liter, dairy milk requires 628.2 L of freshwater vs almond milk requiring 371.46 L of freshwater. And if you use something like oat milk instead that gets you to 48.24 L

    Animal feed is one of the main users of water of the colorado river which is drying up. Large amounts of people depend on that river for their drinking water

    Correspondingly, our hydrologic modelling reveals that cattle-feed irrigation is the leading driver of flow depletion in one-third of all western US sub-watersheds; cattle-feed irrigation accounts for an average of 75% of all consumptive use in these 369 sub-watersheds. During drought years (that is, the driest 10% of years), more than one-quarter of all rivers in the western US are depleted by more than 75% during summer months (Fig. 2 and Supplementary Fig. 2) and cattle-feed irrigation is the largest water use in more than half of these heavily depleted rivers

    in terms of things like emissions, it’s important to reduce meat and dairy consumption to meet climate goals as well

    To have any hope of meeting the central goal of the Paris Agreement, which is to limit global warming to 2°C or less, our carbon emissions must be reduced considerably, including those coming from agriculture. Clark et al. show that even if fossil fuel emissions were eliminated immediately, emissions from the global food system alone would make it impossible to limit warming to 1.5°C and difficult even to realize the 2°C target. Thus, major changes in how food is produced are needed if we want to meet the goals of the Paris Agreement.
