In recent decades, the global warming threat has captured the attention of the nation and the world. While the main focus began with concentrating on the effects this long-term natural crisis would have on the human population, select groups have worked to approach the topic in a manner that entails prevention in order to help other animal and plant species around the globe. One such organization is the National Oceanic and Atmospheric Administration, which has played a major role in the conservation of the polar bear species, one of the mammals most adversely affected by the recent climate changes. As more research has been conducted regarding the polar bears, scientific name Ursus Maritimus, the conclusions have been shocking. In…show more content…

Critical habitat is defined as the “area that contains habitat features essential for the conservation of a threatened or endangered species and which may require special management considerations” (“Critical Habitat”). From this definition coupled with the results of numerous studies, it was found that polar bears have suffered from extreme declines in ice habitats where they carry out the majority of their lives. One study found that “ice thickness has decreased by 40% during the past 30 years and the average annual extent of ice coverage in the polar region has diminished substantially, with an average annual reduction of over 1 million square kilometers” (Schliebe) meaning in a comparatively short period of time the species has been subjected to substantial decreases in their environments. This habitat destruction is the major concern for the polar bear species as human activity is immensely increasing the rate at which their environments are destroyed.

With changing season lengths and temperatures, polar bears
