Collecting seashells is a traditional summer activity, but it significantly impacts beach ecosystems. Current estimates suggest that around 10 billion beach visits occur annually, leading to approximately 10,000 tons of shells being removed each year. Scientific research, including a study at Larga beach, Catalonia, indicates a nearly threefold decrease in shells over 30 years, correlating with a 2.7-fold increase in tourism. The study ruled out environmental factors as causes for this decline, highlighting the impact of human activities on marine environments.
Collecting shells and snails by the seashore is a typical summer tradition, resulting in the annual disappearance of approximately 10,000 tons of shells from beaches worldwide.
Research indicates a drastic decrease in the number of shells on Larga beach in Catalonia, with a reduction of almost threefold during a period when tourism increased 2.7-fold.
