Pollution finds its way to the Arctic from land, sea, and air contamination.
Human’s fishing

maternity dens are located on land where snow accumulates Sows give birth to usually 1 or 2 one-pound cubs
Cubs will remain with their mothers for a little over 2 years.
Female polar bears can produce five litters in their lifetime, which is one of the lowest reproductive rates of any mammal.
Mating Season: Late March - May Gestation: About 8 months with delayed implantation Litter size: cubs; though 1 or 2 cubs is most common
