Luxury cruises on very large ships have become an increasingly fashionable leisure activity, especially among retired people. However, people should not put themselves in danger unnecessarily. Some of the most popular cruises go through parts of the oceans where modern pirates are active. Passengers face a serious risk of being captured and held for ransom or even being killed when the ship is invaded. In addition, it is wrong to benefit from the exploitation of workers. The workers in the engine rooms, laundries, kitchens and restaurants of large cruise ships work long hours for poor pay under appalling conditions and in a culture of fear, facing instant dismissal if they complain about bullying or sexual harassment.
