What happened

The economic ramifications of the closure of the Strait of Hormuz are much discussed.

Why it matters

But so far, the risk of ecological damage following a long blockade of ships has been overlooked.

Common ground

Our recent research shows the more than 1,500 commercial vessels that have been laid up in the Persian/Arabian Gulf since February pose a significant environmental threat because they have been accumulating marine biofouling species on their hulls.

Perspective signals

The tension in the story is sharpened by Loaded Language, Appeal to Fear: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
