Gary Snyder's Turtle Island: Theme

According to Gary Snyder in Turtle Island, change needs to be made.  That is the simple solution behind every poem written, although there may not always be a precise outlook on the future as far as what changes must be made.  The poems are intriguing, allowing the reader to become more interested in nature itself and ways to prevent the damage done so far.  Although they are direct and simple, they give way to meaning beyond what is printed on the pages.  The part that caught my attention was the fact that even though Snyder continuously makes a negative remark towards change, he throws bits and pieces into his poems that equate to hope and peace for the upcoming years.  It seems that a common theme is self vs. nature, referring to the fact that as humans-- as an individual in this society-- we must be willing to devote ourselves to producing change in this world.
