Are the Mediterranean Waters Relatively Free of Pollution?

Introduction

The Mediterranean Sea is often touted as one of the most beautiful and clean oceans in the world, with its turquoise waters and pristine beaches. However, it's important to explore the complexities of ocean pollution and the real state of this iconic sea. While there are indeed areas and times when the Mediterranean is quite clean, it is not without its challenges. This article delves into the pollution issue in the Mediterranean and explains why it might seem relatively cleaner than other parts of the world.

The West to East Pollution Pattern

The Mediterranean is a semi-enclosed sea, with the prevailing winds blowing in a west to east direction. This has a profound impact on pollution patterns. According to environmental scientists, all the garbage and pollution from various European and African countries ends up on the eastern shores due to this wind pattern. A stark example of this can be seen during a strong winter storm, such as the one that affected the eastern shores of countries like Greece, where beaches were left covered in garbage (see the image below).

Waters vs. Shores: A Complex Picture

The Mediterranean is not uniformly clean. While there are spots where the waters are remarkably clear, the shorelines can be littered with waste. After the winter storms, the beach in a town like Rosignano Solvay, in Italy, becomes white with a layer of bicarbonate due to the nearby factory (see the image below). This highlights the issue of pollution not just being confined to the ocean but also affecting the shores in various ways.

Regional Variations in Pollution Levels

The Mediterranean is a vast sea with diverse regional characteristics, which affect pollution levels in different areas. Islands like Sardinia, Baleares, and Sicily, along with coastal regions in countries like Greece, face varying degrees of pollution. For instance, Sardinia and Baleares might have cleaner waters due to less agricultural runoff, while other areas are more impacted by industrial waste and plastic pollution.

Case Study: Cyprus

Cyprus provides a unique case study. In 2018-2019, the waters around the island were notably clean, thanks to its limited agricultural runoff, which prevents the growth of green algae. This example illustrates that there are specific regions in the Mediterranean that manage to keep their waters clean.

Conclusion

In summary, while the Mediterranean Sea is often perceived as relatively pollution-free, it is important to recognize the complexities and regional variations in pollution levels. The wind pattern in the Mediterranean leads to higher pollution levels in the eastern shores, and there are industrial activities that can further contaminate the shores. However, certain regions such as Cyprus, due to their unique geographical and agricultural practices, can maintain relatively pristine waters. The Mediterranean is a remarkable ocean, but it faces challenges that need to be addressed to ensure its long-term health and beauty.
