How Many Gallons of Water to Make 1 Pd Beef

You have already wasted hundreds of gallons of water today, and you probably don't even realize it. Where is all this invisible water going, you ask? The answer is uncomplicated: our food. You volition never see the bulk of water you consume in your lifetime, and this is considering food comprises ⅔ of the average American'southward h2o footprint. Nothing that lands on your dinner plate gets at that place without the use of h2o: crops tin can't flourish without water; the grain we feed our livestock needs water to grow; and fifty-fifty the most processed, artificial foods use water during the manufacturing process. In fact, the agriculture manufacture is responsible for approximately eighty% of the water used in the U.S. So—how to cut downward on your water footprint without starving yourself? It'southward important to realize that when it comes to water, not all foods are created equal. In general, meat has a much larger water footprint than fruits, vegetables and grains. This is because of the massive amounts of virtual water that go into creating food for livestock. Beef—which is the 2nd well-nigh popular meat in the U.S.—has the largest water footprint out of all types of meat, taking a whopping 1,800 gallons of h2o per pound. Manifestly, cutting meat out of your diet birthday would be a great way to adjourn your personal h2o footprint. Just if the thought of living a burger-free being is too much to behave, non to worry—there are other ways to reduce your h2o footprint without giving up steak forever.

For some tips on where to start, VICE Impact talked with Peter Hanlon, Deputy Manager of Programs at GRACE Communications Foundation—a leading, national not-profit devoted to promoting sustainability in food, h2o and energy systems—to get some answers. What goes into our h2o footprint, and how does food fit into that? When we talk about the water footprint, it's really nigh "virtual water" use versus "straight water" use. Well-nigh people are used to thinking nigh their direct water employ—so, h2o that comes out of the tap, out of the shower, flushing the toilet, etc. Only virtual water is the water that goes into producing the food we eat, the energy we employ, and all the products nosotros purchase. People never see their virtual water utilize, so information technology's a harder concept to grasp. But information technology's really a key concept, because the largest part of our water footprint is the water that'south used to grow the nutrient that we consume. Why does meat take a greater water footprint than fruits, vegetables or grains? There'south something called a "feed conversion ratio," which tells us how quickly livestock can turn whatever grain or feed that they're eating into mass. Some animals are pretty efficient, but cows are not and so good at that. Information technology takes a lot of grains or grasses to produce and grow these larger animals for meat. And all those grains and grasses take water to grow in plow. So the water footprint of meat is greater, because you're using products from lower on the nutrient chain to grow something larger. Are there differences between the water footprints of meat raised on a manufactory farm versus meat raised on a free-range farm? When we're talking almost raising livestock, a key concept to sympathize is that the h2o footprint is actually made of three parts: there's the dark-green water footprint, the blue h2o footprint and the gray water footprint. The light-green water footprint, when information technology comes downward to it, is essentially rainfall. The blueish water footprint is the amount of water that's extracted from reservoirs, surface water and groundwater to irrigate fields. And and so the grey h2o footprint is an indicator of the amount of pollution you're causing. For example, if you look at beef that is pasture raised, nosotros're talking about a green water footprint because the animals are eating grass that's being fed by rainwater. But if you look at a more industrial system, we're talking about a larger blue h2o footprint; those cattle start on grass as well, but somewhen they are switched over to feedlots where they're fed grains which are much more intensive in their needs for irrigation. And so there's also the pollution aspect, or grey water footprint. On a pasture-raised organisation, the waste that the cattle are producing is actually used as fertilizer, so it's a benefit. But if you're talking nearly an industrial system, you take 100,000 caput of cattle all pooping in one identify. And all that waste matter is typically moved into a manure lagoon, which is a massive pond of waste matter that frequently can leak. Waste tin leak into the groundwater, it can leak into nearby bodies of water, so instead of that waste beingness a benefit, it tin really be a pollutant. On a personal level—if you don't want to go full vegetarian, how can y'all reduce your water footprint and nevertheless eat meat? First, eat less meat and better meat. In terms of "less meat," you can go "flexitarian," you tin do "Meatless Mondays," or you can even just shrink the portion of meat that yous're serving. Those are all positive things and yous don't necessarily have to "go vegetarian." And then in terms of "better meat," if you choose pasture raised meat certified past a quality third party grouping—something like Animal Welfare Approved or Certified Humane—you can trust that meat will have less affect on water resource than conventionally raised meat. The 2d method to reduce your water footprint, would be eating fewer processed foods. So finally, the third method of reducing your water footprint is to waste less food. About 40 per centum of the food that's raised in the United states is ultimately never eaten, and that accounts for virtually a quarter of the fresh water we consume in this state. All that waste material is just an abhorrent abuse of resources that we accept. Even the simplest thing in the world, similar planning your meals before yous go to the market, can save those resources. This interview has been edited and condensed for clarity.
Whole foods employ less h2o than processed foods. Once you start processing foods, that takes boosted h2o for many different services—anything from creating oils that are used to melt foods to powering the plants that are processing these foods. That all raises the water footprint.
