When it comes to food, it takes, for example, about 18 gallons of water to produce one apple, 53 gallons for one egg, and 2,050 gallons for a pound of beef. Thinking about this can be overwhelming and, of course, we should remember that water is just one aspect among many when considering the links between our diet, the environment, and other factors that might be important to us. But we are committed to learning more.
Personally, I am starting to eat less of certain foods and am especially mindful and grateful when I do eat big water guzzlers. I am also excited to support practitioners of dry farming. In the kitchen, I am using less water for boiling and trying to cook with fewer dishes and utensils so there is less washing up required (for some reason, this is a really difficult one for me, but I am trying!).
