Seashells on the seashore are being taken in large quantities and it's increasing erosion along beaches. A new study reveals the tourism industry is taking too many seashells along coastlines in Costa Rica. 

In this episode of the How to Protect the Ocean podcast, host Andrew Lewin discusses the environmental impact of taking seashells from coastal areas, particularly in Costa Rica. He highlights a growing crisis where the removal of seashells, driven by tourism, destabilizes beaches, accelerates erosion, and harms marine ecosystems. Seashells are essential for various marine species, including hermit crabs, and play a crucial role in maintaining coral reefs and nutrient cycles.

Lewin shares a personal anecdote about a conversation with a friend who chooses not to engage in activities that could negatively impact local environments while traveling. This perspective emphasizes the importance of considering the local ecosystem and communities when visiting new places.

The episode reveals that in 2023 alone, authorities seized over five tons of seashells, complicating conservation efforts due to difficulties in tracing their origins. Innovative solutions, such as using AI technology to classify and return confiscated shells to their natural environments, are being developed to address this issue.

The podcast urges tourists to leave wildlife and natural resources, like seashells, untouched, promoting sustainable tourism practices. Lewin encourages listeners to appreciate the beauty of these natural elements without taking them home, reinforcing the idea that every species plays a vital role in ecological balance for future generations.
