See, it is important to use polar bears because people like them...so scare people about their plight and they won't question global warming...
Here are the ten reasons...

take a look at some real science. from the 2014 report Intergovernmental Panel Report on Climate Change, http://ipcc-wg2.gov/AR5/report/final-drafts/
From Chapter 28, Polar Regions:
The primary concern for polar bears over the foreseeable future is the recent and projected loss of annual ice over continental shelves, decreased ice duration, and decreased ice thickness (high confidence). Of the two subpopulations where data are adequate for assessing abundance effects, it is very likely that the recorded population declines are caused by reductions in sea ice extent. [28.2.2.1.2; 28.3.2.2.2]
and more:
Empirical studies provide direct insight into the mechanisms of climate change impact on polar bears (Ursus maritimus) but modelling allows predictive capacity (Hunter et al., 2010; Amstrup et al., 2010; Durner et al., 2011; Castro de la Guardia et al., 2013).
Polar bears are highly specialized and use annual ice over the continental shelves as their preferred habitat (Durner et al., 2009; Miller et al., 2012). The recent and projected loss of annual ice over continental shelves, decreased ice duration, decreased ice thickness, and habitat fragmentation is causing reduced food intake, increased energy expenditure, and increased fasting in polar bears (high confidence) (Stirling and Parkinson, 2006; Regehr et al., 2007; Durner et al., 2009; Amstrup et al., 2010; Hunter et al., 2010; Derocher et al., 2011; Rode et al., 2012; Sahanatien and Derocher, 2012; Castro de la Guardia et al., 2013).
Subpopulation response varies geographically. Only 2 of the 19 subpopulations, Western Hudson Bay (Regehr et al., 2007) and the Southern Beaufort Sea (Regehr et al., 2010; Rode et al., 2010a) have data series adequate for clear identification of abundance effects related to climate change. Many other subpopulations show characteristics associated with decline but some remain stable. Declining ice is causing lower body condition, reduced individual growth rates, lower fasting endurance, lower reproductive rates, and lower survival (high confidence) (Regehr et al., 2007; Regehr et al., 2010; Rode et al., 2010a; Molnar et al., 2011; Rode et al., 2012). Condition is a precursor to demographic change (very high confidence) (Regehr et al., 2010; Hunter et al., 2010; Rode et al., 2010a; Robinson et al., 2011). The decline in the subpopulation in Western Hudson Bay by 21% between 1987 and 2004 was related to climate change (medium confidence) (Regehr et al., 2007).
Replacement of multiyear ice by annual ice could increase polar bear habitat (low confidence) (Derocher et al., 2004). Increasing the distance to multiyear ice and terrestrial refugia at maximal melt may result in drowning, cub mortality, and increased energetic costs (Monnett and Gleason, 2006; Durner et al., 2011; Pagano et al., 2012).
There is robust evidence of changes in sea ice conditions changing polar bear distribution including den areas (high confidence) (Fischbach et al., 2007; Schliebe et al., 2008; Gleason and Rode, 2009; Towns et al., 2010; Derocher et al., 2011). The number of human-bear interactions are projected to increase with warming (high confidence) (Stirling and Parkinson, 2006; Towns et al., 2009).
Use of terrestrial resources by polar bears was suggested as adaptive (Dyck et al., 2007; Dyck and Romberg, 2007; Armstrong et al., 2008; Dyck et al., 2008; Dyck and Kebreab, 2009; Rockwell and Gormezano, 2009; Smith et al., 2010). Polar bears cannot adapt to terrestrial foods (Stirling et al., 2008b; Amstrup et al., 2009; Slater et al., 2010; Rode et al., 2010b), and will most likely not be able to adapt to climate change and reduced sea ice extent (very high confidence). Changing ice conditions are linked to cannibalism (Amstrup et al., 2006), altered feeding (Cherry et al., 2009), unusual hunting behaviour (Stirling et al., 2008a), and diet change (Iverson et al., 2006; Thiemann et al., 2008) (medium confidence).
Theres more, it's a big report, but this is real science. Something you might want to acquaint yourself with.
