The question "do cruise ships empty sewage in the ocean" refers to a controversial practice where cruise ships release untreated or partially treated sewage directly into the marine environment. Like many industries, the cruise industry has a responsibility to minimize its environmental impact.
The practice of discharging sewage into the ocean has been a concern for environmentalists and regulators for decades. Sewage contains harmful bacteria, viruses, and other contaminants that can pollute the ocean and pose health risks to marine life and humans. In the past, many cruise ships routinely dumped untreated sewage into the ocean, but in recent years there has been a growing movement towards more environmentally friendly practices.
