In no more than 500 words please use the script outline below to write a short script about why the city of Venice in Italy is sinking.
|The floating city Venice, is slowly sinking into the Adriatic Sea. But why?||*generic picture of the city of Venice|
|Purposely built on the water to avoid invaders, the Roman citizens in 420 AD required security as the western half of the Roman Empire was being invaded||https://www.gwern.net/docs/eva/1996-newtype-anno-interview|
|A barrier from northern invaders, the swampy waterway by the sea has turned from friend to foe. Water continues to flood the streets of Venice, damaging the historic mertopolis||*video of flooding||https://www.gwern.net/docs/eva/1996-newtype-anno-interview|
|But like everything these days, it’s more complicated than that||Tag before intro|
|There exists two forces pulling Venice into the Adriatic: one is human the other natual. So let’s start with the Venetians who settled in the city.|
|The habitants of the inlands by Venice, wanted to build a home on the swamplands that are now Venice|
In order to secure their homes, Venetian architecture implanted long pointed poles of wood; oak, larch, or pine, straight down into the seafloor. Two layers of horizontal planks were laid out. Layered with stone, these techniques laid the foundation for the city
Sudmerged in water, these wooden poles actually became STRONGER as the surrounding saltwater pertified the wood hard as stone
So if the structures were built to get stronger why is Venice sinking?

|Surrounded by wood strengthening saltwater, Venice has struggled to acquire good drinking water. As the city grew this issue became a real problem|
In the 1960s artisanal wells were dug into the clay that supported the wooden poles. This weakened the structural integrity of the wood, and the city began to sink, fast!Later outlawed, studies in 2000 showed the rate of sinking slowed considerably
|Problem solved right? Well not so much|
A new study in the journal Geochemistry, Geophysics, Geosystems found Venice was subsiding on average about 1 to 2 millimeters a year (0.04 to 0.08 inches per year). According to the study:
“Our combined GPS and InSAR analysis clearly captured the movements over the last decade that neither GPS nor InSAR could sense alone”
This is where the natural forces sinking Venice come into play

|Far below the swamp, Venice sits on the Adriatic plate|
Literally caught between a rock and a hard place, researchers found the tectonic plate below Venice shuffling underneath the nearby Alpiennes Mountains. These seismic activities have been pushing Venice further into the sea.
Add to that the effects of rising sea levels and Venice is being drowned from both sides.
The twin processes of human acitivity and geological change have subsided the city by about 120 mm in the 20th century. In addition the sea level has risen about 110 mm in the same time
|Scientists estimate that the city and surrounding land could sink by about 80 mm (3.2 inches) relative to the sea in the next 20 years.|
Providing shelter from barbarian invaders, the likes of Charlemagne and even Atilla the Hun, the citys biggest strength is also its fatal weakness. Water built Venice up, and it looks to be swallowing it whole
