One of the most important topics in the world at the moment is the environment: humanity is gradually destroying its natural environment at an alarming rate; and what can be done to prevent our environment from fulfilling its premature destiny, which is closely tied to the one that humanity will face. Humans have always been in close contact with the aquatic environment. Due to environmental awareness, the sea came into focus relatively late compared to other natural areas. Independently of this observation, the sea has historically served as an important transportation route and source of food and recreation. In a world where more than 70% of the surface is covered by oceans, our interaction and dependence on the sea is evident in many respects. Since in everyday life, we encounter and of course depend on the issue of environmental management efficiency. Therefore, the cruise industry considers the best opportunity to gain the practice of balancing ecologically healthy actions and increasing. As is widely known, hosting enormous amounts of people creates significant piles of waste, and the regulation of waste disposal at sea is limited. This is partly due to the cruise industry not being subject to the same environmental standards as the land industry and because it is difficult to control or enforce.
