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?
1_Wizard
Mollusc Shells are a good example.

I see. Like Oysters and so forth. I love eating oysters, though I'm allergic to shrimp.
1_Wizard
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.
