When we think of preservation, we unilaterally think of environmental protection.
Preservation concerns us all! Rivers, rivers, lakes, coasts are priorities for protection, but we must keep in mind that the preservation of these environments commits us to the protection of goods and people. Existing and future structures, bridges, dykes, dams, ports, etc., deserve our attention by taking into account environmental protection but also by being attentive to the implications on our living environment.
Preservation issues must be taken into account to promote the natural flow of water by paying attention to urbanization and its inhabitants.
