There has recently been a huge mine accident at the United States. It happened at the Massey Energy Co. in Montocoal, Virginia. This tragic accident included the death of at least 25 people. Nobody knows what the reason for this accident is. There has been a case of a mine accident on 2007 at a mine called Grandall Canyon, Utah, 6 miners were trapped. This is believed to be a criminal act. Many more mine accidents have happened at the USA. During time, mines have become a safer place. In the past, many more people would die of mine accidents than today. For example, on December 6, 1907, 362 people died because of the accident. Now, about 5 people die per accident.
My opinion about this is that its better that people are now safer inside the caves and that less people are dying. I also think that caves are really dangerous because it can fall anytime because its dirt.

What the author thinks of this is that there have been many accidents and its dangerous but it just a normal thing.
