1.Define biodiversity and explain why biodiversity has been threatened. (150~250 words)
Biodiversity is the variety of the living organisms and ecological complexes, richness of living organism. It can be a small scale or a large scale. Climate, geological history affect to the biodiversity. Now we want to talk about threats of biodiversity. Extinction is a natural event, we know that most of species have gone extinct. As the living organism extinct, biodiversity is threatened. What make the extinct happen? There are many reasons for that. As we learned from the module, H.I.P.P.O can be the good criterion. It is Habitat loss, Invasive Species, Pollution, Human Population, and Overharvesting. Today, due to increase of human action, so many species have been threatened. For example, since we need more land with increase of the human population, people execute deforest. As a result, many living organisms which lived in that area will lose their living foundation. Climate change also one of the biggest reason. Since the distribution of species is to a great extent dictated by climate, just like the appropriation of biological systems and plant vegetation zones. I think those 5 listed events are closely related to each other. Most of them resulted by human action and each event occur other events.
2.Give an example where biodiversity is very high and describe the area. (100~200words)
When I saw the term biodiversity, the first place popped up in my mind was Korean DMZ (demilitarized zone). In the midst of worldwide strains and military acting, the Demilitarized Zone (DMZ) isolating North and South Korea has, for about 65 years, provided sanctuary to creatures and plants which endangered and threatened. The DMZ has been unbendingly upheld. It is uninhabited by people, and its isolation has permitted harmed woodlands to restore and farmlands that are a large number of years old to come back to a characteristic state. This natural detachment area along the 250 km (160 mi) length of the DMZ has made an involuntary park which is presently perceived as a standout amongst the most all around saved territories of calm living space on the planet. So the Korean DMZ is an example place for variety biodiversity and since no one has access to the DMZ, people assume it is possible that there are more species than what we expected.

Hi, My name is Sarah, and here is a link to my blog post: http://geog030.dutton.psu.edu/2016/04/15/module-10-biodiversity-15/.
I really liked all of your questions! I found your second question and answer very interesting, especially towards the end when you said “since no one has access to the DMZ, people assume it is possible that there are more species than what we expected.” It’s so crazy to me thinking about all of the species on earth and all of the species yet to be discovered. In this week’s module, it talked about how 300 new species were documented on an average day. It fascinates me to think about all of the species that we’re living with on this earth that we don’t even know about. Great post!
