These days the environmental buzz is all about carbon. People, businesses and even countries are talking about their "carbon footprint" -- or the impact of their activities on the environment in terms of the greenhouse gases produced (and measured in CO2). As we evolve in our consciousness about how our consumption affects the world around us, and what we can do to live equitably within the bounds of our planet's resources, we need to consider much more than just carbon.
A next step is water. Many of us in the developed world rarely give it a thought. We turn on our drinking and shower taps, and clean water comes out. We flush our toilets and magically, the waste disappears. We turn on our sprinklers and green lawns abound. We run our dishwaters and washing machines and fill up our pools and hot tubs, often without thought.
As our climate crisis becomes a part of daily consciousness, our energy future will need to match our water future. The two are inextricably linked.
And today, on World Water Day, it is the perfect time to ask: How much water do we use?
A new website, H2O Conserve, allows you to actually calculate how much water you use so you can begin to assess your "water footprint." As their site explains, "Your water footprint takes into account not only the water used in your home, but also the water that is used to produce the food you choose to eat and the products you buy. Your water footprint also includes other factors, such as the water used to cool the power plants that provide your electricity and the water that is saved when you recycle. You may not drink, feel or see this water, but it makes up the large majority of your water footprint."
On a global scale, water consumption varies greatly. It is estimated that, in order to survive, a person needs 4 to 5 gallons of water per day -- this includes water for drinking, cooking and sanitation. The average water use per person per day, just for domestic purposes in the United States and Canada is actually around 150 gallons. In Europe, things are different. With roughly the same standard of living, the average resident of the United Kingdom uses 31 gallons per person per day. And of course, in the developing world, the numbers are a stark contrast. The average person living in Africa uses 5 gallons per person per day, which means that in many areas, people are getting even less water than that -- and often not enough to survive. Globally, a staggering 25,000 people die daily from lack of access to clean water.
While the water consumption rates for the United States seem high in comparison, the amount of water we all use is actually even higher. These statistics consider only the basic domestic water use, but the H2O Calculator gives a more holistic view of what impact we have on our water resources. This includes where our energy comes from, the products we buy, how much we drive, whether we use bottled water, and the kinds of food we eat.
The website also goes a step further -- once you know your shocking number (and yes, you'll probably be shocked by the actual number of gallons you use in a day because it's more like 1,000 and not 150) -- there is a ton of information that helps you figure out how to cut that footprint down. Some things are definitely lifestyle choices, like how far you drive and the vehicle you use to get you there. Or the kind of food you eat -- eating lower on the food chain, less meat and dairy, saves a lot more water.
Some of the tips are also pricey and geared more towards homeowners, like when you're in the market for new appliances, choose Energy Star-rated ones or get a rain sensor for your automatic sprinklers on your lawn (or better yet, use xeriscaping). Of course, replacing toilets, showerheads and faucets with low-flow/flush versions save a lot of water and aren't too expensive. Likewise, setting up rain-harvesting or graywater systems to reuse water (although not for drinking) is a great way to cut back on water consumption without shelling out a ton of money. After all, do we really need to be using potable water to flush our toilets and water our lawns?
But there are also lots of tips for people that may be renters or apartment dwellers and aren't able to change their appliances or install solar panels. Here's a few: Recycle and reuse products in your home; buy whole instead of processed foods; only run the dishwasher when full, and if washing by hand, don't leave the water running; save water you use for boiling, and let it cool and then use it for your plants; be speedy in the shower; and the list goes on. A lot of it is common sense or what you may have heard from your parents or grandparents, but much of us could probably use a reminder.
