Transcript of Polar Bears

Polar Bears Endangered Species Act An endangered species is a species with few animals, or the number of animals is declining very quickly, that is may soon become extinct.
The ESA outlines an endangered species as any species which is in danger of extinction throughout all or a significant portion of its range other than a species of the class insecta determined by the secretary to constitute a pest whose protection under the provisions of this act would present an overwelming and overriding risk to man.
www.epw.senate.gov/esa73.pdf
Endangered-threatened or exposed to danger...Example- Florida Panther
Threatened- any species which is likely to become an endangered species within the forseeable future throughout all or a significant portion of its range...Example-Galapagos Marine Iguana
Extinct-a species that is no longer in existence... Example-Kakapo
We should protect endangered species because they are of esthetic, ecological, education, historical, recreational, and scientific value to the nation and its people. Threats Artic Sea Ice is melting at an unprecedented rate. They need the ice to access their food and to move from hunting grounds to their dens.
Toxic Chemicals and oil exploration disturb thier habitat.
Hunting
Human induced climate change
Artic tourism, minerals, and energy development are affecting the polar bears. Tourist want to get closer to them, yet when their campground food attracts the bears, they are attacked.
Polar Bears are so well insulated they tend to overheat. Because of their physicality, the ecosystem is highly dependent on all its parts, so without them we might loose other species as well, loss of natural preditors, overpopulation, sickness, and mass die offs may occur. Habitat-live in the circumpolar artic, near land masses, the edges of the polar basin artic ice, water, island, and continental coastlines.
Life History
Age of Maturation-Males(10-11 years) and females(5-6 years)
Number of offspring- usually 2 in the first litterand 1 in the following litters
Mating- male and female find each other by congregating in the best seal hunting habitats; males compete for females and the 2 stay together for a week or more; ovulation is induced and an egg is fertilized
Diet- ringed and bearded seals, beluga whales, bowhead whales, walruses, and narwhals
How it lives- they are communal Specific Endangered Species Conservation Efforts VIDEO

“We work to secure a future for all species, great and small, hovering on the brink of extinction. We do so through science, law, and creative media, with a focus on protecting the lands, waters, and climate that species need to survive.”
