In the modern world, global warming, poverty, and hunger are some of the most common problems that are worried for, but there is another global problem that is often neglected. Species are dying, which in turn causes the loss of biodiversity. In order to have a sustainable environment, there needs to be an increase in biodiversity. Biodiversity refers to the variety and variability of life on Earth. The number of species of plants and animals are both part of the biological diversity of the Polynesia-Micronesia hotspot. The loss of biodiversity in this hotspot damages crucial services provided by nature. A biodiversity hotspot is a region with a significant amount of organisms that are threatened by humans. The Polynesia-Micronesia hotspot is one of the smallest hotspots, covering only 46,315 km2 of land. This hotspot includes all the islands of Micronesia, Polynesia, and Fiji. There are more than 4,500 islands, representing eleven countries, eight territories and the state of Hawaii and are characterized by their high levels of biodiversity and species endemism (Atherton et al, 2007). These characteristics qualify the Polynesia-Micronesia area as a hotspot. The islands of Polynesia-Micronesia vary from rocky islets, low lying coral atolls, and uplifted limestone islands to larger, higher volcanic islands (McGinley, 2011). The wide geographic range and thousands of isolated island ecosystems have led to high levels of endemism in this hotspot. One of the key factors to…
