Environmental Degredation - Pollution

With increasing level of industrialization, Antarctica is now facing tremendous threats to its environment. The enlarging ozone hole has been a concern for more than 20 years since the problem first surfaced. The hole allows excess amount of ultraviolet radiation to pass through. It is formed due to presence of some chemicals released during human activities like CFCs.

The excess ultraviolet radiations will cause anomaly, disorder of diseases in human, such as skin cancers. The agents causing ozone depletion come from human activities in other regions. Thus it is obvious that Antarctica, the cleanest part of the world, can be used as a mirror reflecting the minor changes in pollution level, by censoring the amount of pollutants present in its precipitation, soils and oceans.

Casual pollution also goes along everyday in Antarctica, featuring as oil spills and flotsam. Predictably, oil spill is the increasing amount of oil present in Antarctica due to frequent regional shipping activities. This is due to waste oil remained on the facilities on ships.

Another environmental nightmare in Antarctic waters is flotsam and debris lost overboard from ships. Waste products such as will have damaging effect to wildlife. Fishing net and fishing line may trap seals and sea birds. Animals may also be injured and led to slow death.
