Ecological Reflections

 * To go to the snow, you need, if you do not know exactly the route, go with a guide
 *Not drinking alcohol at least one day before you go
 *About two weeks ago eating foods that provide calories, preparing to leave
 *Wear clothes and shoes suitable for the cold and the walk
 * No littering on PNN
 * Caring vegetative species that are there
 * Going green in your daily life, and that global warming is slowly killing the Snowy, and other PNN
