Polar Bears - What the Future Holds
Polar Bears have always been the focus of attention for nature lovers and researchers. The development of technical means of wildlife research has provided for greater opportunities to study this amazing mammal, which is the largest on earth. Acquiring more knowledge on the species is instrumental in helping it to survive. Moreover, Polar Bear population trends are a good indicator of the Arctic's state. Therefore, data supplied by various researches are of great significance.
Satellite tracking, one of the most recently developed and most efficient means of researching the species, allows scientists to learn more about individual Polar Bears and to trace their movements and home ranges. Infrared thermal sensory equipment can help to find Polar Bear dens beneath the snow.
It is now evident that the Polar Bear has no natural predators and may suffer from starvation, disease, and climatic changes. Global warming can affect the species in a drastic way by depriving it of its natural habitat. Ice melting does not allow the Polar Bear to travel and reproduce. Based on recent research, a model of what is going to happen in the Arctic region was developed. It is believed that the Arctic may get deprived of the ice within the next 50 years. Recent data shows that the ice thickness has diminished by 40% during the last three decades.
Human disturbance of the Polar Bear is also a great concern for environmentalists. Polar Bears are greatly impacted by oil spills, shipping, hunting, etc. Many countries join efforts to reduce the impact of the human activities on the species and learn more about the ecology of this largest mammal. It is essential to get profound knowledge on the boundaries of the species, its relations with the seals, and affects brought about by climatic changes. New methods of exploring the nature of Polar Bears are also needed.
