Shipwrecks may have redeeming ecological value. The ships often become artificial reefs and habitats, providing shelter for the very creatures threatened by humanitys original intrusion.

“Ships made of wood provide a different hosting environment than those built of steel,” says Benayahu. “Steel is a very successful choice of reef as wood decays. Steel structures are also covered fast by calcareous algae, which provide an adequate surface for coral larvae to grow quickly.”

Another advantage of artificial reefs is that they can enhance the development of rare coral species that are not often found in natural reefs.
