Under pressure: raising Venice above water (using... water?)
Two factors are exacerbating the flooding risk to the city: global sea level rise and subsidence. In short, sea is rising and the city is sinking. Like other cities built on river deltas, the sediment beneath the city is compacting over time. In a natural setting, this compaction would be offset by the deposition of fresh sediment at the surface, but the rivers feeding the lagoon were diverted in the 1500s. As a result, the land surface is sinking, and the salt marshes are suffering for it.


I won't spoil on how exactly water is being used solve Venice's water problem.

Shower Heads That Save Water and Still Feel Good
In the pursuit of saving water — finding a low-flow shower head with high pressure — I took an inordinate number of showers, sometimes several a day. I compared the merits of 17 shower heads, each with a standard half-inch connection. Criteria included how well each could deliver an acceptably robust shower, and the usefulness of the various spray options. Also, I tested the flow rates stated by the manufacturers with a bucket and stop watch. Everyone told the truth.
