What are the Human uses of a peninsula

What do humans use peninsulas for OTHER then living on? It has stumped me...

Peninsulas often have good harbors. Fishing around a peninsula can be better than in the open ocean. Peninsulas are easier to defend than mainland sites, and so can be protective (at least before modern times, where airplanes and rockets can go anywhere). A peninsula that sticks out into an ocean with a warm current can have a better climate than the mainland. A peninsula often gets more rain than the mainland because of moisture taken up from the ocean.

Those are the ones that come to mind. there are probably some others.

It depends upon what the peninsula happens to offer. It may or may not provide farmland. It may or may not have towns and factories on it. It may or may not attract toursists. It may or may not have fishing ports and / or beach towns. It may or may not be used for military bases and training facilities. It may or may not have a navy habour. It may or may not have civilian port facilities.. It may or may not have wildlife reserves. It may or may not have quarries. It may or may not provide clay resources. And so on and so on with many may or may nots.

What activities occur vary from place to place. All of the above points, and many more, happen to be relevant to peninsulas on the southern coast of Dorset in England. There's even a prison on one of those peninsulas, so you could include that as well.
