The people of Lau Lagoon build islands on the reef as this provided protection against attack from the people who lived in the centre of Malaita.
These islands were formed literally one rock at a time. A family would take their
canoe out to the reef which protects the lagoon and then dive for rocks, bring them to the surface and then return to the selected site and drop the rocks into the water. Living on the reef was also healthier as the mosquitoes, which infested the coastal swamps, were not found on the reef islands. The Lau people continue to live on the reef islands.

s and disrupts marine life. The increased amount of sand, sediment, and fine particles creates turbid conditions, blocking necessary UV rays from reaching coral reefs, creating coral turbidity (where more organic material is taken in by coral) and increasing bacterial activity (more harmful bacteria are introduced into coral).
The construction of artificial islands also decreases the subaqueous area in surrounding waters, leading to habitat destruction or degradation for many species.
