We waste about half our food in America, and that wasted food accounts for about 2 percent of annual energy consumption in the U.S. Now comes news that the water used to produce the food we throw away is about 1.5 the amount of water we use in our homes!

That study, conducted by the Waste & Resources Action Programme and WWF — is actually for U.K. homes. But “the problem is unlikely to be restricted to the UK,” according to New Scientist. Titled “The Water and Carbon Footprint of Household Food and Drink Waste in the UK,” the study shows the huge impact of the food we throw away:

Our research has found that the water footprint of avoidable food waste is 6,200 million cubic metres per year representing nearly 6% of all our water requirements. In per capita terms, this is 243 litres per person per day, approximately one and a half times the daily average household water use in the UK. A quarter of this water footprint represents water used to grow and process food here in the UK, i.e. water from the UK‟s rivers, lakes and aquifers.
This week happens to be World Water Week — a time when people are hopefully fixing leaks and adopting water-wise habits. Want to try a World Water Week resolution? Try to reduce your food use for the rest of the year. Your fellow MNN readers offer lots of tips to help you get started.
Wasted food wastes water too
A new study shows that avoidable food waste sucks up six percent of the water used in the U.K.
