what does saving a polar bears cub relates to being a christain?

The above link leads to a story where some animal rights groups want this poor polar bear cub that was rejected by the mother to let him die rather than a human caring for it. I think from scriptures what the zoo is rightfully doing is saving the polar bear cub. I really hate the darwianian survival of the fittest mentality which these animal rights groups espouse.

Let us look at what the bible says about man and his relationship with creation:

15And the LORD God took the man and put him into the Garden of Eden to dress it and to keep it. (gen 2:15)

Yet You have made him but a little lower than God [or heavenly beings], and You have crowned him with glory and honor.
6You made him to have dominion over the works of Your hands; You have put all things under his feet:(A)
7All sheep and oxen, yes, and the beasts of the field,
8The birds of the air, and the fish of the sea, and whatever passes along the paths of the seas.

(psalms 8:5-8)

6Your righteousness is like the mountains of God, Your judgments are like the great deep. O Lord, You preserve man and beast. (psalms 36:6)

10You make springs gush forth in the valleys; they flow between the hills; 11they give drink to every beast of the field; the wild donkeys quench their thirst. 12Beside them the birds of the heavens dwell; they sing among the branches. 13From your lofty abode you water the mountains; the earth is satisfied with the fruit of your work.

14You cause the grass to grow for the livestock and plants for man to cultivate,that he may bring forth food from the earth (psalms 104:10-14)

we christains are called to be like our heavenly father and one of the things we reflect this besides:

living life of holiness,of doing good etc is taking care of animals.
