What would happen if he basking shark became extinct?

If the basking shark became extinct, it would disrupt marine ecosystems as they play a role in maintaining the balance of plankton populations, which are crucial for ocean health. Their absence could lead to overpopulation of certain plankton species, potentially affecting the entire food web, including fish and marine mammals that rely on a balanced ecosystem. Additionally, the loss of basking sharks would diminish biodiversity and could impact ecotourism, as these gentle giants attract divers and researchers. Overall, their extinction would have significant ecological and economic consequences.
