 The Mediterranean Sea is heavily polluted with plastic waste, especially in the Pelago Sanctuary. Researchers have found that the amount of plastic waste in the sea is higher than expected, and it is likely to be affecting the local wildlife, including the endangered fin whale. This research has shown that the amount of plastic waste in the sea is highly correlated with the presence of fin whales, indicating that they are being exposed to harmful levels of plastic waste.
