However when saying that I assume that the people on land also know of this. The humans would be worshipping Ursula for a different reason, than the mermaids.

The mermaids were granted legs, once a year. The humans want the seas to remain calm, and safe for travel. All things considered, it is pretty safe to assume Eric's kingdom is located near the ocean.... a mermaid spied on him and fell in love, seafood will be served at the ball.
