It is home to 150 million people along its coastline (roughly equivalent to Russia's population). And it sequesters 17.2 million metric tons of CO2 each year. Joining the Newscast this week to talk about the unique biodiversity of the Mediterranean Sea and its threats is journalist Manuela Callari. Callari has written for Mongabay, highlighting the threats to purple sea urchins (Paracentrotus lividus) along the Italian coast. These marine invertebrates are crucial to the health of marine ecosystems, such as those in the Mediterranean, by helping regulate algal abundance and serving as food for predators. However, they are being overfished and even poached in marine protected areas due to demand for them as the primary ingredient in a popular tourist dish: spaghetti ai ricci di mare. While the situation with urchins persists, Italy has been investing in an unprecedented effort to map its entire underwater coastline using deployed sensors to better understand the marine environment and manage conservation efforts. This is allowing them to identify where meadows of the seagrass Posidonia oceanica, which are “absolutely vital” to the Mediterranean ecosystem, persist, Callari says. Overall, Callari says she wishes the rest of the world and tourists visiting the Mediterranean were more informed about the pressures the marine ecosystem faces. “I grew up here, and now that I go back to certain places where I was as a child, and they are just completely different places to me. Places that were just nature and were difficult to access. Now they have very easy access on cars, buses. You can go on boat tours very easily. And I think we don't appreciate enough the impact that has on the environment. On the sea.” Please take a minute to let us know what you think of our podcast here.
