Recently there have been some movies released about sharks.   At the same time there has been news from all over the world about people being attacked by sharks.   It seems like whenever summer comes around,  similar incidents occur.  

My impressions of sharks comes from the movie  "Jaws",  which I watched as a child.   The background music became such a classic that it left people with the thought of fear whenever they heard it.   In addition,  in some animal documentaries,  we can see scary clips of sharks hunting for food.   I have seen sharks in some aquariums and find them to be very beautiful animals.   Today,  the fishing habits of some people have become so aggressive that it has disrupted the natural food chain.   This is something that really requires our attention.
