Increased human activities in the Arctic have raised concerns over the destruction of polar bears habitat. Conservationists have been complaining that activities such as oil exploration and hunting may develop into a drastic decline in the population of polar bears. Most of these activities results into adverse climatic changes which alters the ecology, a situation which strains the creation of these animals. Recent research studies have indicated that unless the key actions are implemented, polar bears may be annihilated before the end of the 21st century (Garner 221). As a result of enhanced communication channels, human beings are better informed of the dangers that uncontrolled human activities cause to both the atmosphere and polar bears. This is preferable to the fact that researchers’ views are easily disseminated to the societies around the world. This paper seeks to analyze polar bears, their habitat, as well as current conservation efforts (Best 1035).

Like other marine animal, polar bears trap warm air by its white fur made of hollow hairs. Light from the sun changes the black skin of polar bear into warmth. These make polar bear dry and warm while it is swimming. They have short ears and tail, this adaptation help to conserve heat. Polar bear feed on bearded seals and they hunt at the interface between ice, water, and air (Durner et al 60).
Advance in technology has facilitated research on polar bears in the past 20 years. Satellite telemetry enables polar bear researcher to keep in touch with individual polar bear over a long period. This has significantly enhanced knowledge of polar bear movements and their family bounds. Infrared emission sensory gadgets help in identifying polar bears hideout under the snow. Aircraft and vessel transportation provide an approach to a larger percentage of swam of family of polar bear. Technology advance also allow for poly-disciplinary explore on polar bear population. These technology advances allow for improved exactness in constituting management conclusion and righter understanding of danger and results of management activities (Calvert and Ramsay, 450). In yesteryear, the large conservation deck for family of polar bear was the reality that polar bear habitat was comparatively.
Polar bear spends most of their life at sea. Their favorite environment is the yearly sea ice overly over the continental shelf. These areas have massive biological fertility in comparison to deep water. Seals are the main diet of polar bear, and they migrate due to appear and disappear of water throughout the year due to weather changes and polar bears must follow their prey. When ice melts entirely in each summer, polar bear go onto land and wait the next freeze-up. Polar bear migrate in summer to areas that remain frozen year round (Knick 226).
Effect of Climatic Changes
Current environmental changes due to modeling of climate style indicate that polar bear habitats will experience drastic changes in the near future, and this will significantly affect polar bear population. Continuous effect of climate change on polar bear family is not certain but, minor change in clime may have a heavy effect on family of polar bear. Increased snow cause a reduction in successful seal birth lairs this causes population of polar bear to decrease. Decrease snow affects seal whelping by not rendering enough snow for construction of birth lairs thus decreasing seal productivity (Kostyan 210). These will cub polar bear survival and production. Climatic alteration that change period of snow coverage could affect dissemination and impact population of polar bears. This could cause bears to spend most of their time on the land. Polar bears hideout could be affected by unusual warm enchantment. This may limit or restrict polar bears accessing their dens this would impact on breeding and survival of polar bears. Rain can cause polar bears snow dens to collapse or be opened to hash environmental conditions. Warmer temperature could cause a reduction in physical and breeding of polar bears in such areas. Organic pollution places an additional area of increasing fear in population of polar bears (Garner et al 225).
International Conservation Efforts
Population of polar bears has declined in the past few decades. This has caused the world conservation union to upgrade polar bear to a vulnerable species from a species of least concern. International involvement in the conservation of polar bears began in 1965 when scientists from different countries met to discuss their conservation. This was due to widespread concern that they were being over harvested (Kostyan 214). Different countries have signed an agreement to co-manage shared subpopulation of bear. An international group formed to conserve polar bear coordinates research on polar bear. These involve conducting studies to assess effects on polar bear immune and hormone systems.
Climatic change and human activities have enormous significance on population of polar bear. Heavy rain and warming affect the habitat of polar bear. Polar bear spend most of their life in the arctic sea and only move to land when snow melts and only return in the next freeze-up. The white fur made of hollow hairs, short tail, and ears make polar bear dry and warm. Advanced technology facilitates monitoring of polar bear which help in conservation of polar bears. Different countries have signed an agreement to co-manage shared subpopulation of bear. There is an international group called Polar Bear Specialist Group that involves with conservation of polar bear (Best 71). This group coordinates research on polar bear and assesses effects on polar bear immune and hormone system.
