While on a family trip, one might visit large national parks, small botanical gardens, or arboretums. This involves environmental education– also in a mobile form. Thanks to natural atlases, users of smartphone applications can familiarize themselves with regional fauna and flora by using the “keys” to identify various species, animal footprints, and bird voices. Boards with QR codes might also be of use. Those who aren’t particular fans of mobile systems will find printed publications and websites as an invaluable source of information.
