From a dangerous point of view, I must say that the sea is very scary.
People cannot survive in water, which means that the sea can become a threat to people's lives at any time. If you are unfortunate enough to be adrift at sea, your chances of survival will be very slim if you do not find land within a short period of time. First of all, solar radiation at sea is more than twice that on land, there is not much difference between you and staying in a solar oven. This type of radiation will make people very thirsty, but sea water has a very high salt content. If you choose to drink sea water, it will be equivalent to death. The most terrifying threat at sea has never been endangered great white sharks, but lack of food, lack of fresh water and endless despair.
If you are unlucky enough to be on a sailboat at sea, it will be even more tragic, because the chances that thesailboat is rescued are very thin and almost no one will survive the arrival of help. . If the boat capsizes, it will sink into the sea and people will hardly be able to survive at sea for long without a carrier.
Of course, the sea still gives people a lot of fantasy. The vast sea is beautiful, so even though it is dangerous, many people still yearn for it.
