What '?

is set up as environmental disaster a phenomenon with a large effect on the 'environment , natural and not understood in a biological sense, that is catastrophic:

• the relative abundance of living organisms involved;
• the severity of the effects of these bodies;
• the vastness of the territory concerned.

It includes, for risks incurred potentially catastrophic environmental disasters also touched.
events may be caused or encouraged by the action of a particular animal species, usually the man. L ' man himself and his territory are naturally ascribed to all concerned, and subject to disaster. Less frequently, instead of the disaster comes from the action of other animal species: it is generally non-native breeds but artificially introduced that destroy the habitat created in time and without their presence.
We can distinguish between:

• disasters caused by the direct action of man and its activities;

• disasters caused by other breeds.

The environmental disaster not to be confused with natural disasters or natural disasters, ascribed all-natural events. Often, however, these natural phenomena receive an amplification effect due to human activities, fading out the boundary between the two categories. For example, deforestation of a hilly area, so a direct environmental disaster, can turn a relatively harmless storm in a devastating landslide that without human intervention would be classified a natural disaster.
