The changing of temperature influence their reproduction cycle, growth pattern, and resulting species movement as well as animal interaction (Friedman L.S, 2012). The declining of the polar icecap because of the warm temperature may affect the availability of polar bear prey, which is seal. The decreasing number of the fish that the seal eat near the productive area in the icecap affects their nutrition status and reproduction rates (National Wildlife Federation).
