Technosphere

The thirst of humans and our technology for water, according to two important studies, is bottomless and accelerating, even if the precious liquid itself is finite on this planet. One study shows that human activity has massively altered the world’s flow of surface water and imperilled water cycles critical for life as varied as fish and forests. The other confirms that in many places on Earth aquifers and groundwater wells are being pumped and mined faster than they can be replenished. The concept of the technosphere helps to explain the forces in play.
