The professor begins by telling the students that the keystone speices in Africa is the elephant.He states that a keystone speices is defined as an animal that has an incredibly the large effect on its environment.

To begin with, elephant eat around 500pounds of vegetation a day.This keeps the forest from expanding too much. Something which would in convinience other animals to the point that they would either migrate from the region or merely die off. Also, when elephants wander and defecate, they enrich the soil and plant seeds that will become other plants and trees. Animals can then use these plants as food sources.

In my opinion, the Jeju island is the most memorable plce. First of all, it has special environment. I could see lots of black stones and strange tropical plants. Second, it has places for tourists. For example, a hot air balloon of a tangerin orchard. Consequently, it is my memorable city in my thought.
