It's highly misleading to suggest that the net impact of cycling a gallon of agricultural water (including irrigation + rainfall) is equal to that of a dumping a gallon of drinking water (packaged and delivered to your door, no less!) down the drain, of course.
Also, while the water footprint of almonds (and pistachios, cashews, etc) isn't great, if you aren't comparing it to that of other high-impact foods (in terms of water use by weight of end product) like say, dried tomatoes, butter, or most four-legged meat products -- not only per gram of end product, but per recommended serving (which for nut products is comparatively modest) -- then you're not only not helping us understand how we got into this mess (and how to get out); you're just pushing people's buttons, basically.
