(Easy and very simple tips for eco-friendly lifestyle; but enough to help conserve the treasures of nature.)
When you are out walking in nature, be discreet. Make as little noise as possible and, if you want to see wild animals, avoid wearing bright colours or smothering yourself with perfume.
Always keep to the paths so that there is less risk of disturbing animals or of stepping on plants, mosses, mushrooms, etc. If you take your dog with you, keep it on the leash or make sure is does not stray off the path. Also make sure that it does not bark and scare away nearby animals—in fact, if you want to catch sight of animals, it would be better to leave your faithful companion at home.
Finally, do not throw any rubbish away in natural surroundings and only pick or collect what is allowed.
