What is the author's style in the nonfiction book, The Worst Hard Time?

The account is presented in mainly a journalistic style which is not surprising since Egan is a reporter. There is a contemplative element to the presentation; a manner that reproaches mankind’s misuse of land and disrespect for Mother Earth. There was no need to add drama to the story of the Dust Bowl, there was plenty of drama in the actual events and the stories of the people who suffered so severely and lost everything including finally their dreams and all hope.
