What would happen without seals?

Without seals, marine ecosystems would face significant disruptions as they play a crucial role in maintaining the balance of their environments. Seals are vital predators, helping to regulate fish populations and maintain healthy marine biodiversity. Their absence could lead to overpopulation of certain fish species, resulting in imbalances that affect other marine life and ecosystems. Additionally, seals contribute to nutrient cycling in the ocean, and their decline could impact the health of the entire marine food web.
