What conflicts in the novel represent Man vs. nature or Man vs. Society?

Most people know Jack London for his stories about the North. His short story, "To Build a Fire," is one of the most well known American short stories, and both White Fang and The Call of the Wild are well-read and well-loved novels. The main conflict in all of his stories is man vs. nature, or, in White Fang, dog-nature vs. wolf-nature. Although White Fang is not human, the book illuminates the wolfish qualities of both men and animals, and the way that humans shape lesser creatures. The wild is certainly juxtaposed with civilized society. White Fang can't live in a city. He must be in the wild, it is his very essence.

Any Quotes from the story that show this?

Here is one for Man vs Nature,

On the sled, in the box, lay a third man whose toil was over, - a man whom the Wild had conquered and beaten down until he would never move nor struggle again. It is not the way of the Wild to like movement. Life is an offense to it, for life is movement; and the Wild aims always to destroy movement." - Jack London, White Fang, Part 1, Ch. 1
