Hazard (Global)
Hazard (Global) :
changes to regional ecosystems which in turn effect global systems, are termed global hazards. Climate change, soil degradation, and deforestation are examples of global hazards that are directly and indirectly related to the manipulation of technology. Global hazards can be distinguished from the more traditional ones because of their diffused or dispersed effects at the planetary scale - they threaten the long-term survival of t he planet.They are not rare, discrete events but develop over a long period of time. Global hazards are cumulative in nature and are the end result of centuries or decades of human manipulation of technology to control nature and exploit its resources (Cutter 1993, 5).
