When I first read this infographic on water usage from Loch Ness Water Gardens, I was amazed at how many gallons of water it took to produce one glass of orange juice (45 gallons) or just one egg (53 gallons). It got me thinking that from a sustainable travel point of view, as healthy and fresh water becomes more scarce in many parts of the world, it would be relatively easy for me to forgo certain foods while traveling. What do you think? What would you try giving up during your travels? Here are quick tips for saving water when traveling by utilizing the concept of a water footprint.
Saving Water When Traveling Means Different Food Choices
A water footprint measures the amount of water used to produce each of the goods and services we use. It can be measured for a single process, such as growing rice, for a product, such as a pair of jeans, for the fuel we put in our car, or for an entire multi-national company. The water footprint can also tell us how much water is being consumed by a particular country – or globally – in a specific river basin or from an aquifer.
Water footprint covers not only the water we use directly every day but also those that were used in making our food or the products we use. For example, a slice of bread requires 10 gallons of water; that is the total amount of water needed for growing the wheat and sugarcane, raising chicken for the eggs, manufacturing the flour and sugar up to the baking process of the bread. That is a lot of water for a single slice of bread! In the Philippines, every person uses an average of 3,800 liters of water daily.
