There are more and more constructions at sea, threatening the diversity of marine ecosystems.

00:00:05.480 --> 00:00:07.760
Living seawalls were created in Australia

00:00:07.760 --> 00:00:14.040
by Alex Goad, Melanie Bishop, Katherine Dafforn
and Mariana Mayer-Pinto.

00:00:15.000 --> 00:00:21.040
They are panels hung on constructions that create habitats where invertebrates and seaweeds live and grow.

00:00:22.040 --> 00:00:27.840
Like with reefs, fish also shelter in the panels
where they find additional food sources.

00:00:29.040 --> 00:00:34.960
In areas with Living Seawalls, the number of fish seaweeds
and invertebrates increased up to a third.

This trademarked brand of the Sydney Institute of Marin science is hoping to promote cleaner and healthier seas.
