Thinking about what I want to eat for dinner, I don’t often consider how my choices are impacting the environment. The agriculture and livestock industries require massive amounts of water; with this said, some choices for dinner are more environmentally sustainable than others. According to Kai Olson-Sawyer, a Senior Research and Policy Analyst in the GRACE Water and Energy Programs, “the total amount of water needed – to produce one pound of beef is 1,799 gallons of water; one pound of pork takes 576 gallons of water. As a comparison, the water footprint of soybeans is 216 gallons; corn is 108 gallons”. Thinking about the amount of fresh water required to raise livestock vs grow crops, choosing a plant-based diet is much better for long-term environmental sustainability, due to the extreme strain on our water resources from the livestock. The extensive amount of water required to raise animals comes partially from how much the animals need to eat and drink, as well as the number of animals that are produced in our massive food industry, especially in the United States. Due to the large differences in water requirements for production, plant-based diets contribute to much better environmental sustainability than diets that include meat.
