Humans cannot drink saline water. But, saline water can be made into freshwater, which is the purpose of this portable, inflatable solar still (it even wraps up into a tiny package).

How does water pollution affect drinking water?
As ground water works its way through the soil, it can pick up excess nutrients and transport them to the water table. When polluted groundwater reaches drinking water systems it can pose serious public health threats. ... Some of these waters are impaired or affected by excessive amounts of nitrogen and phosphorus.
Water pollution occurs when harmful substances—often chemicals or microorganisms—contaminate a stream, river, lake, ocean, aquifer, or other body of water, degrading water quality and rendering it toxic to humans or the environment.
Deforestation and poor farming practices also make the problem of water pollution worse.
