The same must so be used of way of not altering the balance necessary to guarantee the existence of those same living beings, that is not to unbalance the environment. The intention of this is not to offer a global vision on the diverse uses that become of the territory, but an analysis of the implications that certain interventions of the man can cause on the environment.
