Un environnement climatique et géologique en perpétuel changement a créé, au fil des siècles, la diversité du monde vivant qui nous entoure. Ce patrimoine dont l'inventaire reste inachevé est pourtant menacé. L'activité humaine détruit de nombreux milieux naturels, entraînant la disparition de milliers d'espèces. La recherche d'un équilibre entre les contraintes du développement économique et le respect de l'environnement est désormais indispensable si l'on veut préserver la richesse même de notre planète.
