Which of the following is NOT a consequence of poor ballast water management?

The choice that is NOT a consequence of poor ballast water management is improved ship stability. Effective ballast water management is critical for vessel stability and safety. When ballast water is not managed properly, it can lead to an improper distribution of weight, causing ships to become unstable and potentially leading to capsizing or other operational issues.

Conversely, poor ballast water management can lead to several negative consequences like flooding due to improper weight distribution, the introduction and spread of invasive marine species—which can disrupt local ecosystems—and contribute to an imbalance in marine ecosystems. These consequences underline the importance of managing ballast water effectively to ensure oceanic health, ship stability, and compliance with maritime regulations.
