Catastrophes caused by man are undesired events that are created by intentional doing or not doing of man, and whose consequences have harmful influence on man or nature. We are talking about a unexpected event of inconceivable proportions which leads to negative changes in the environment.

According to definition of Interpol, those events are characterized by a large number of victims, or a lot of damage that cannot be repaired with local assets.

According to consequences, catastrophes that are caused by man can be: ecological and humanitarian. In the case of ecological catastrophes there are spills of foreign matter into the ecosystem, while in the case of humanitarian catastrophes human life or health is endangered.

Unlike natural disasters, whose effect cannot be predicted or prevented, disasters that are caused by man occur often as the consequence of negligence of men. The data that in the last decades number of such accidents is constantly growing. Nonstop development of industry and economy leads to frequent spills of chemical matter in water, and cases when oil spills into oceans and seas are not rare which frequently damages the water ecosystem. Cases of disasters in nuclear power plants are not rare when there is release of large amounts of radioactive material. We all remember nuclear disaster in Japan or the EXPLOSION OF NUCLEAR REACTOR IN CHERNOBYL, which left behind a large number of victims and damage of incalculable proportions.
