The main difference between the two writing is that Carson is concerned about the destruction of the entire environment, while Muir is only concerned about a certain part of the environment. John Muirs present evidence to persuade and encourage the readers to rescue the Sequoia meanwhile Rachel Carson shows a fictional story of what life would become if we do not save the environment.
<span>Carson is concerned about the destruction of the entire environment, while Muir is only concerned about a certain part of the environment.</span>
Hmm...an easier way to find a theme of the story would be either scheming through the story looking for clues or facts or read it.
I hope this answer helps.
