‘Water, water everywhere, but not a drop to drink.’ This poetically plagiarized prose precedes an International Energy Agency (IEA) report. As the climate changes, so do our precipitation expectations, and the latest portrait drawn by the IEA makes those words look like a possible future photographic caption. Water demand is expected to double by 2035, according to the IEA. Around half of the projected 66 billion cubic meter increase will be swallowed by coal production. This is equivalent to the residential consumption of everyone in the US for three years. The United Nations estimates that 1.8 billion people will have to deal with severe water scarcity and two-thirds of the population will be living in ‘water-stressed conditions.’
Fortunately there is no guarantee of being stuck out at sea sans both paddles. Water awareness is a good first step, and you can simultaneously cut your carbon and water footprint, since water, agriculture and energy are so intertwined. We’ve mentioned before how becoming a weekday vegetarian can save you around 2 tons of carbon, there are also benefits for your water footprint. The average American diet uses around 1,000 gallons a person everyday. Choosing to eat less meat and dairy and (if you are eating meat) picking grass-fed over grain-fed can make a real difference. National Geographic estimates that a vegan consumes around 600 fewer gallons of water than the average American. Then there’s all the embodied water in the energy you consume and the products you buy, many of which come from water stressed regions of the world. So as you buy less stuff and make your home a model of energy efficiency you’ll also be working water wonders for the people and ecosystems that need it most.
