    How much water it takes to create 30 common items

    The world is in a water crisis. From dirty water in Flint, Mich., to droughts in Arizona, California, and South Africa, the human population seems to be spiraling toward a world with less water. Even though water is a renewable resource, there is still a finite amount in our lakes, rivers, and oceans.

    A person uses between 80 and 100 gallons of water a day by flushing toilets, taking showers, running facets, washing clothes, starting the dishwasher, and watering outdoor lawns. However, that number doesn’t take into account the amount of water used to make common items people use on a daily basis.

    Everyday items like computers, smartphones, T-shirts, jeans, shoes, coffee, eggs, and dog food carry a water footprint. The water footprint of a product is the amount of water that is consumed and polluted in all processing stages of its production. Call it grey water, virtual water, or something else—the things people use every day are produced with hundreds of gallons of "hidden" water. Consider these examples. A pound of almonds takes nearly 2,000 gallons of water to grow. It takes more than 3,400 gallons of water to produce a smartphone, 6,000 gallons of water to run a 60-watt lightbulb for half a day, and 200 gallons of water to make one bowl of dog food.

    To find out how much pressure everyday products are putting on the world’s finite freshwater supply, Stacker’s researchers analyzed the water footprint of 30 common household items. Click through the list to see how much water is needed to make each of these items and discover more eco-friendly alternatives.

    Set of car tires

    It takes around 2,074 gallons of water to produce a set of car tires. The vast majority of tires are made from synthetic rubber, which needs water to be produced. During tire production, water is also used to create hot steam that molds the tire itself. To save water, people can use bikes with smaller tires as their primary transportation.

    A cup of coffee

    It takes significantly more than a cup of water to make a cup of coffee. It takes about 37 gallons of water to grow and process the number of beans needed for a single cup. Unfortunately, the only way to be more eco-friendly about coffee is to drink less coffee.

  • A ton of steel

    A ton of steel

    In the 1960s, it took 34,000 gallons of water to make a ton of steel, and that number has gone up. Current estimates are almost double that number, at 62,000 gallons for a ton of steel. Water is used in the production process to cool the metal, scrub the steel, and descale the materials.

  • Blue jeans

    Blue jeans

    About 2,000 gallons of water go into creating a single pair of jeans, thanks to the cotton growth and apparel manufacturing processes. However, water usage in blue jeans production can be cut by more than half. Levi Strauss & Co. focuses on water sustainability and has managed to get water consumption down to 998 gallons per pair, and that includes the water used to care for them at home.

  • Smartphone

    A pint of beer

    The four main ingredients in beer are hops, yeast, barley, and water. It takes about 20 gallons of water to make a single pint, a number that combines the water used in the brew and through the growth cycle of the plants. Luckily, brewers have caught on and are starting to use more water-friendly production methods.

  • Car

    60-watt lightbulb

    A 60-watt incandescent lightbulb, when left on for 12 hours a day in a year, uses up to 6,000 gallons of water. The water is used for either cooling generators or producing steam. Energy-efficient lightbulbs are more eco-friendly alternatives, as they require less water consumption.

  • Pound of beef

    Pound of beef

    It takes 1,799 gallons of water to produce a 16-ounce steak because that's how much water a cow consumes before it arrives on someone's dinner plate. Going vegetarian is more eco-friendly because vegetable production uses significantly less water.

  • A gallon of wine

    Plastic water bottle

    A plastic water bottle has a relatively low water impact compared to the rest of the items on this list. However, it takes a bit more than three-quarters of a gallon to produce a quarter-gallon (or 1 liter) bottle. Most of the water consumption happens during oil drilling. Still, people can save extra water and plastic usage by switching to reusable water bottles.

  • Computer

    Polyester shirt

    Throughout their entire life cycle—from production to washing to disposal—two cotton shirts use more than 7,000 gallons of water. Polyester, on the other hand, is a synthetic fiber that's significantly less thirsty; two polyester shirts (equal to about one kilogram of the fabric) will only use 501 gallons of water.

  • One slice of bread

    One slice of bread

    About 172 gallons of water are needed to produce the grain for a loaf of bread. That means a single slice uses around 11 gallons. Eating lettuce wraps or sandwiches with thinner bread slices are more eco-friendly alternatives.

  • One sheet of paper

    A pound of chicken

    Chicken has one of the lowest rates of water usage among meats. Producing a pound of chicken requires 468 gallons of water. However, producing healthy chickens for human consumption still uses significantly more water than vegetable production. Ditching meat altogether is a far more sustainable option.

  • One lumber board

    One chocolate bar

    You need about 450 gallons of water to make a single chocolate bar. The vast majority of the water is used to grow the cocoa plants needed to create chocolate. Luckily for chocolate lovers, it's not that wasteful—most of the water used to grow cocoa is rainwater, thanks to the plant's ideal growing climate.

  • $1 worth of pet food
