In are our nation's treasures in danger what is the author's point of view about the people who damage national parks

Gordon refers to these people as "souvenir hunters." A souvenir hunter is someone who takes a small piece of a national park (for example a rock or a leaf) as a memento. Since the souvenir is so small, these people may not realize the damage they are causing; however, since so many people visit these parks, all the tiny "souvenirs" add up to a lot of damage.
