Discussion: Extinctions and Endangered Species
In this module’s discussion, we will learn about the economic and ecological impact of habitat loss on the island country of Micronesia. The Federated States of Micronesia is a country spread across the western Pacific Ocean comprising over 600 islands. Micronesia is made up of 4 island states: Pohnpei, Kosrae, Chuuk and Yap. Watch the following video link about climate changes in Micronesia: http://www.pbslearningmedia.org/asset/prcc12_vid_mctprob1/
As you watch the video, focus on how life has changed for the islanders and the land itself.
What are some specific examples from the video that suggest ecosystems and the islanders’ way of life are changing?
What is a biodiversity hotspot? How does Micronesia meet the criteria for a biodiversity hotspot?
What are some of the causes for the loss of biodiversity in Micronesia? Describe at least one of the native species (either plant or animal) that is under threat due to habitat loss or degradation.

Specific examples that suggests ecosystems and the islanders way of life are changing is it takes a full day of fishing to get a good amount of fish. However, 15-20 years ago it only took half of a day. Another example is back in the day before the water hit the ocean it was white water and not it is brown or red. And the last example is one of the little islands that one of people owns it now under water, so they are unable to use it. (Craig Musburger, n.d.)
Biodiversity hotspot per Science Daily is, “A biodiversity hotspot is a biogeographic region that is both a significant reservoir of biodiversity and is threatened with destruction.” (n.d.) What makes Micronesia a biodiversity hotspot is it is home to, “1400 species of plants, including 200 found nowhere else in the world, 1300 species of fish, 483 species of corals, 85 species of birds, and 66 species of plants and animals listed as endangered or threatened.” (Craig Musburger, n.d.) Micronesia is a biodiversity hotspot because they have a huge level of biodiversity and the issues they have like water rising, the temperatures rising causing coral reefs to die off, and long periods of drought is what is causing it. (Craig Musburger, n.d.) What also makes Micronesia a biodiversity hotspot is the fact there are 66 species that are endangered or threatened. (Craig Musburger, n.d.)
Some of the causes for the loss if biodiversity is rising temperatures of the water, which is causing the coral reefs to lose color and die off. (Craig Musburger, n.d.) I’m sure plants are also dying off due to the droughts and with the water rising, animals will have to abandon their habitats to get to higher ground. How much longer though before all of the islands are underwater though, if the water keeps rising. We would lose so many different species once this happens. As I stated above a specific plant that is threatened right now is the coral reefs due to the rising temperatures.
