Traditional agriculture uses 70 percent of the water on the planet. Hydroponics is 70 percent more efficient than traditional agriculture. Aeroponics, meanwhile, is 70 percent more efficient than hydroponics. Thus, if we used aeroponics for agriculture, we could drop water use from 70 percent to 6 percent—quite the savings. With the threat of water scarcity getting more serious every day, it’s hard to believe these technologies haven’t been widely adopted.
