Natural Heritage
Preserving the natural patrimony is the most inexpensive and efficient environmental economics. The term natural heritage derives from the French "patrimoine naturel", the totality of natural assets, including those of historical, cultural or scenic beauty. It give us understanding the importance of natural environment: where we came from, what we do and how we will be. Our lives are connected to the landscapes of our daily lives, as well as we keep the memories of places we went. The destruction of these landscapes cause irreversible environmental damage, and are an insult to our memory, causing loss of quality of life.
