At first it seems baffling that it could take up to 7 litres of water to make a bottle of water or 140 litres to make a cup of coffee. The statistics get worse when you look into meat and dairy production with 2,000 litres of water going into 1 litre of milk or 1kg of beef. Where is all this water going?
In the case of coffee, it is a very thirsty crop, often grown in a hot climate. It is also grown in countries where irrigation systems have been stretched to the max, these tired systems can be inefficient with the water they carry.
With bottled water it is the bottle itself that is the culprit. To make the plastic, mould it, mass produce it and maintain the factory where it is created.
For beef and dairy it is not just the water that the cows consume, it is the water that it takes to grow the food they eat. The grass or corn or alfalfa that they eat needs water to grow and one average cow can consume up to 76kg of grass per day.
So is water labeling the solution? I do believe that we as consumers need to become more aware of the amount of 'virtual water' we consume. In Ireland it is often easy to forget that water isn't so easy to come by elsewhere. I have just finished reading Fred Pearce's 'When The Rivers Run Dry' which paints a pretty bleak picture of our world teetering on the edge of water poverty. Centuries of bad water practices, of dams and irrigation systems that rob some rivers of so much of their flow that they fail to reach the sea. Of drained and polluted aquifiers, of farmers who dig wells deeper and deeper yet they still run dry. Each of us need to take responsibility for the amount of virtual water we consume, we may switch off the tap whilst we're brushing our teeth but to really make a difference perhaps we should cut down on the amount of coffee we drink, the amount of bottled water we buy or the amount of meat and dairy we consume? Water labeling will educate us, will make us aware but my fear is that another label on our food, without a massive marketing campaign to back it up, could just be lost amongst our certified organic, fair trade, carbon footprint and nutritional information.
