Natural disasters seem to abound at the moment, and the latest one is the Chile earthquake. Of course, it is not going to be the last and it was followed only a few days later by mudslides killing large numbers of people. There is a difference between natural disasters, which we really cannot do anything about other than in terms of how we react and how one builds in earthquake zones, and human-caused environmental disasters and damage which is invariably the case in things like mudslide when natural vegetation and trees are removed and the land damaged.
