Complex environmental alterations damages human body defence system: a new bio-systemic way of investigation

摘要

Few studies focus on environment in its biological dimension, relating territorial/landscape alteration and human health, beyond pollution impact. The growing importance of risk factors in medicine and the new ecological advancements in Landscape Bionomics impose to deepen these studies. The landscape is a living entity, in which man and territory form a complex biological level of life organization. So, a landscape must be investigated in its physiology and behaviour by the discipline of Landscape Bionomics. This to check "if", "how" and "how much" landscape alterations could reflect on human health, independently form pollution. First evidences of a clear correlation subsist, concerning an increase of mortality rate within Milan hinterland (Italy). The Landscape dysfunctions are correlated with the increase of mortality rate MR. All the environmental alterations are registered as 'stressors' by a basilar ethological alarm process. So, bionomic landscape dysfunctions may attempt our health bringing to an excess of cortisol, which reduces our hormonal, immune and nervous system defences. This enlarges the W.H.O. estimation of the environmental MR and the importance of applications impose a true effort in landscape rehabilitation.
