In these days I am in Cambados, in Galicia, for a European solidarity project, and I have had the opportunity to observe closely how strongly this area is connected to the sea. Life here revolves a lot around fishing and shellfish farming, especially in the Rías Baixas area, where the sea enters the land forming inlets that are very rich in biodiversity.

One of the most important activities is the cultivation of mussels on “bateas”, which are floating platforms. It is a traditional system but still very productive today, which makes the area one of the main European centers for seafood.

• The problem of plastic pollution

During this project, I also reflected on a problem that affects almost all seas: plastic. Plastic waste reaches the sea from rivers, cities, and also tourism. The main issue is that plastic does not disappear, but breaks down into smaller and smaller pieces called microplastics.

These microplastics easily enter the marine food chain. Mollusks, such as mussels, filter water to feed and can therefore accumulate these particles. This not only harms the animals, but can also become a problem for humans who consume these products.

In general, the effects are: 

•⁠  ⁠loss of quality of the marine ecosystem

•⁠  ⁠risk for wildlife that ingests plastic

•⁠  ⁠possible contamination of food

•⁠  ⁠damage to coastal biodiversity

• What can be done to improve the situation 

In my opinion, also based on what I have seen and learned during this project, solutions need to be practical and involve everyone.

First of all, it would be important to reduce the use of single-use plastic, especially in sectors related to tourism and fishing. Then, waste management in ports and coastal towns needs to be improved, to prevent it from ending up directly in the sea.

Another important point is innovation: using more sustainable materials for nets, equipment, and packaging in the fishing industry.

Finally, I believe it is also essential to raise awareness among people. Often the problem comes from everyday behaviour, so educating citizens and tourists can really make a difference.

Being here in Cambados has helped me understand even better how the sea is both a fundamental and fragile resource. Fishing is an important part of the local culture and economy, but without attention to sustainability it risks being damaged in the long term.

Protecting the sea means protecting the future of these communities.
