84、The country Myria, which charges fees for the use of national parks, reports little evidence of environmental damage. This strongly suggests that for the country Illium, the best way to preserve public lands is to charge people more money when they are using national parks and wilderness areas for activities with heavy environmental impact. By collecting fees from those people who overuse public lands, Illium will help preserve those lands for present and future generations.
