Why it is important for ships to sanitize ballast water?

Sanitizing ballast water is crucial to prevent the spread of invasive species, pathogens, and harmful microorganisms that can disrupt local ecosystems and damage marine biodiversity. When ships take on ballast water in one location and discharge it in another, they can introduce non-native species, leading to ecological imbalances. Additionally, untreated ballast water can pose health risks to humans and marine life. Effective sanitation practices help protect both marine environments and global shipping industries.
