Seagrass and Beach Cleaning: How New Rules Are Changing Mallorca's Coasts

Answer

Why is seagrass left on some Mallorca beaches instead of being cleaned away?

Washed-up Posidonia and other seagrass are often left on Mallorca’s beaches because they help protect the coastline. They hold sand in place, support water quality and play an important role in the marine environment. Many people may see them as beach waste, but ecologically they are part of the natural system.
