World Water Day: Humans are guzzling too much water

With World Water Day, the United Nations will draw attention towards mankind’s water consumption, especially in industrial nations. Today, about 7 billion people live on our planet. The number is expected to grow by about 2 billion by the year 2050. Of course, each one of them will need water. That includes drinking water as well as water used in every day life, like for showering or food production. All together, that adds up to a lot of water. Just keep in mind, producing one kilo of beef consumes 15,000 liters of water, and one kilo of wheat guzzles up 1,500 liters.
The United Nations recommends a sustainable diet. That means we should be aware of how water-intensive products are. We also should reduce the amount of food we waste, says the UN. 30% of the food produced worldwide is thrown away. The water used to produce it is therefore lost forever. You can learn more about the World Water Day on the official UN website.  The latest Environmental Outlook report by the OECD also draws a bleak picture on rising sea levels that are swallowing cities and millions of people who will be suffering water shortages.
The UN also provides a very interesting FAQ about the value of water. Facts and figures about water can be found from the National Geographic.  If you are a U.S. resident, the National Geographic provides another interesting feature, a water footprint calculator to estimate your water use on a daily basis.
