It may seem harmless, but you should avoid taking seashells when you're visiting the seashore. With beach-bound tourism on the rise, visitors taking home shell souvenirs can wreak havoc on natural ecosystems that depend on the shells, which are a vital material resource for nearly every type of aquatic wildlife. Birds use them for nests; fish hide inside them; hermit crabs use them for shelter and even microorganisms need them to survive. And even broken shells are vital, so leave them as well.
