Oldspeak: ‘So. There’s that. This should come as no surprise, as Humans are currently consuming this irreplaceable and rapidly dwindling resource at an unsustainable rate at the same time that sources of fresh water are rapidly drying up due to Anthropogenic Global Warming. Right now, 1 in 9 humans don’t have access to safe water. 2.5 billion do not have access to adequate sanitation. With expected increases in population, by 2030, food demand is predicted to increase by 50% (70% by 2050) (Bruinsma, 2009), while energy demand from hydropower and other renewable energy resources will rise by 60% (WWAP, 2009). These issues are interconnected – increasing agricultural output, for example, will substantially increase both water and energy consumption, leading to increased competition for water between water-using sectors. Oh, and 85% of the world population lives in the driest half of the planet. SO as temperature rises, a lager and larger majority of humans will not have water to drink. In short, this is a recipe for extinction. Raising prices won’t help. Recycling won’t help. We will exceed the biocapacity of our planet, and that will be it. Hellacious paradox really. Lack of water on land will kill us, and overabundance of sea water will drown us. (2/3rds of people live near coastlines.) ” -OSJ

The world will only have 60% of the water it needs by 2030 without significant global policy change, according to a new report from the U.N.
While countries like India are rapidly depleting their groundwater, rainfall patterns around the world are becoming more unpredictable due to global warming, meaning there will be less water in reserves. Meanwhile, as the population increases, so does demand for potable water, snowballing to a massive problem for our waterways in 15 years’ time.
The report suggests several changes of course that nations can take, from increasing water prices to finding new ways of recycling waste water.
