Sea is not really dangerous. It depends on what you do there. If you dont swim in the ocean without any safety suits then you can get killed by the sharks in the sea. The sea is even providing us food like fish and other sea foods. Sea is also providing us caragenan which is used to make plastocs and gels. Salt comes from the sea. Sea can help us a lot if we know how to use it to our advantage.
