I'm a local and whilst I'm not an advocate of Sandbanks, your representation from as early as at 0.41, is wholy inaccurate - we don't have cliffs - Sandbanks is a - wait for it, a Sandbank (clue is in the n ame,  it ain't Cliffbanks!).

The ferry does not and never did connect Sandbanks to Poole.  It connects Sandbanks to Shell Bay (which is part of Studland near Swanage). To get from Poole to Sandbanks, the route is by road only and takes under 20 minutes.

many of these photos dont show sandbanks ..

Such a pity that 99.9999 percent of the pictures are nothing to do with Sandbanks.
As the No50 Purbeck Breezer travels downhill to Shore Road, Poole Harbour looks like heaven on earth on a sunny day. Then over on the chain ferry to Studland and onward to Swanage. England at its very very best ❤

Absolute nonsense. The majority of your photographs do not feature Sandbanks. Other places entirely.

I visited there many times, once the hotel at the harbour entrance. It is a crowded but lovely place, the blue sky and glittering water, the quality of light. Possibly the best climate in England. I love it there. Easy to understand it's appeal.

Beachhuts at sandbanks were only for Poole residents to rent from the town council. My grandparents had one and Tony Blackburns family was next-door door, but 1. When my grandparents passed away, it reverted back to the council onto the 'beachhut waiting list'.

A teacher at school told me sandbanks would be gone in 10 years, it looks the same to me 25 years later.

A lot of these photos are not of Sandbanks and include misleading images of other Dorset beaches suffering from erosion.

Too many photos which aren't Sandbanks

Some very interesting information, but I am not sure how relevant a picture of a bombed out Camden Town tube station  is

Forty years ago you could not walk along the beach to the Haven hotel as the tide came up to the houses, all the beach was under water. Now they beach is much bigger. There was a beach at low tide but not at high tide.

Poole has always been connected by land to Sandbanks. The author of the commentary clearly never visited.

The sea is not making Sandbanks disappear and the cliffs you showed collapsing are not anywhere in the Sandbanks area. Speaking to residents that live on the shoreline they will tell you the sea level is if anything receding.

It's good that the other side of the Harbour isn't built on .

Repetitive unnecessary waffle, incorrect pictures, and incorrect intonation always exposes lazy and tiresome AI.

As a Brit and long time S Florida resident, I can tell you that the same thing is happening in Miami.  Every coastal town or city on the planet is subject to shifting sands and the force of nature.  S Florida beaches are periodically being replenished with truck loads of sand, many times after a major storm.  Just because a piece of land exists doesn’t mean it’s suitable to build on.  With rising seas, millions of people are potentially at risk in the future.

When I was working down in Wimborne 1977 me and my mate were going to buy a beach hut not far from sandbanks for £ 300 pounds but he could not get his half of the money what a mistake that was they now can sell for £105.000 pounds

Fun fact: a very close male relative of mine (not sure which but probably the brother of my great grandfather, whatever that would make him to me) was offered an opportunity to buy half of this peninsula (or whatever you call it for £300 around the turn of the century. He said no, thinking nothing would ever become of the place.

I think you've missed the point completely. If and when that spit ever washes away, that will effectively become an island. The prices of those properties will skyrocket. Look elsewhere around the world. They will either leave it as an island or build a private bridge, which will probably have security at the entry point, where you will be required to present an invitation (permission) pass or a resident's pass. That exclusivity will drive property prices into the sky.
