Ok, so that’s what Pacific environments used to look like, but… Exotic plants / Agriculture Urbanization Complete devastation Exotic animals Heavy use of marine resources

Taro

Pandanus

Introduced species..

Giant Snails

Threats and changes to to marine ecology Development and use of the coastlines Dams, upstream chemical contamination Overfishing (size effect) Dynamite and cyanide fishing Coral bleaching (warming climate) Introduced species, predatory species (crown-of-thorns starfish)

Threats to marine areas:

Overview… Some patterns…. Richest areas of productivity and species are in the western pacific and decreases as you go east. Richest at conjunction of land, air and water and gets less from there. (sea grasses, reefs and mangroves) The more ecological niches, the more species.
