Pollution
The ozone hole is the best known example of pollutants that are produced in one place, but have their effects in another. As Antarctica is one of the cleanest, least polluted places on earth it is an ideal location for measuring the spread of global pollutants. Minute traces of man-made chemicals used in other parts of the world can be detected in the snow that falls over the region. They become concentrated in the bodies of local wildlife such as seals and penguins.
Oil Spills
Threats facing
Antarctica
Oil spills are an increasing form of pollution in Antarctica as a result of increasing shipping activity in the region. While ships often have facilities to contain waste oil and separate oil from water which is then taken out of Antarctica for disposal, an ever greater presence is bound to lead to more accidents which do happen. In recent years there have been a number of groundings of tourist ships in shallow, poorly chartered waters and also accidents involving fishing boats in pursuit of the Patagonian tooth fish.
Flotsam
An increasing problem in Antarctic waters (and in the rest of the world too) is flotsam and debris lost overboard from ships, particularly fishing ships. Bits of fishing net, fishing line, boxes, strapping bands etc. might sound harmless if unsightly, but they can have a deadly effect on wildlife.
