What is one key goal of ballast water management?

One key goal of ballast water management is to prevent ecological disruptions caused by non-native species. When ships take on ballast water in one location and later discharge it in another, they can inadvertently introduce aquatic organisms into new environments. These non-native species can outcompete local flora and fauna, leading to significant ecological imbalances, loss of biodiversity, and alteration of habitat structures. Effective management practices aim to treat or exchange ballast water before it is discharged, ensuring that the organisms present are native to the local environment or are otherwise not harmful. This is essential for protecting marine ecosystems and maintaining the health of coastal and marine environments.
