In are our nations treasures in danger what is the authors point of view about the people who damage national parks?

The author’s view of people who damage national parks can be interpreted to be somewhat forgiving.  It is forgiving in that the author most likely feels that those who damage and/or cause destruction to national parks do so ignorantly because as he quotes a park ranger, “…the vast majority of people are just making an innocent mistake” such as taking a small piece of petrified wood or tossing a penny into a geothermal vent.

what that mean can you explain please
