I love going to the beach, though I burn easily.
I love the beach!  Sand can be biological in origin, like shells and algae.
Really? So what kinds of creatures are these shells the remains of?
Mollusc Shells are a good example.
I see. Like Oysters and so forth. I love eating oysters, though I'm allergic to shrimp.
Shrimp is very good.  The cuisine in the US reflects it's history, and we have a deep history in fishing.
Yes, indeed. I used to live in Louisiana, where eating shrimp is a way of life.
Louisiana also has a rich people, back to the Creole people who descended from the inhabitants of colonial Louisiana from those born elsewhere.
Yes, and New Orleans is a very rich city culturally.
Indeed.  It is a major United States port and the largest city and metro area in Louisiana.
