=== Environmental effects ===
The reduced heterogeneity in sea floor landscape introduced by breakwaters can lead to reduced [[species abundance]] and diversity in the surrounding ecosystems.<ref name=":1">{{Cite journal|last1=Aguilera|first1=Moisés A.|last2=Arias|first2=René M.|last3=Manzur|first3=Tatiana|date=2019|title=Mapping microhabitat thermal patterns in artificial breakwaters: Alteration of intertidal biodiversity by higher rock temperature|url= |journal=Ecology and Evolution|language=en|volume=9|issue=22|pages=12915–12927|doi=10.1002/ece3.5776|issn=2045-7758|pmc=6875675|pmid=31788225}}</ref> As a result of the reduced heterogeneity and decreased depths that breakwaters produce due to sediment build up, the UV exposure and temperature in surrounding waters increase, which may disrupt surrounding ecosystems.<ref name=":0" /><ref name=":1" />
