Blockchains & Circular Economy Strategies in Water Recycling and Reuse
Water covers two-thirds of the world, but only 1% of it is suitable for human use. On Earth, there are 326 million trillion gallons of water. The remaining 97 per cent is saltwater, which is unfit to drink. Freshwater makes up 2.5 per cent of the total, but most of it is locked in the poles or deep below. This leaves us with about 0.4 per cent to distribute among the 7 billion people on the planet.
