Final answer:
In Jack London's The Call of the Wild, Buck's life in the Santa Clara Valley is depicted as peaceful and luxurious before his forcible removal to the harsh environment of the Klondike, marking a stark contrast between comfort and survival.
Step-by-step explanation:
Jack London's novel The Call of the Wild begins by depicting Buck's life as idyllic and comfortable in the Santa Clara Valley before he is sold into the harsh realities of the Far North. In the tranquil sunny Santa Clara Valley, Buck, a large and powerful St. Bernard-Scotch Collie, lives a pampered life on Judge Miller's estate where his biggest concerns are leisurely swims and hunting with the Judge's sons. Buck's initial existence is marked by a sense of domestic bliss, security, and primacy among the estate's other dogs. This serene life stands in stark contrast to the brutal and survivalist world he is thrust into following his abduction. As Buck is dog-napped and sold as a sled dog during the Klondike Gold Rush, his narrative becomes a poignant exploration of the inherent conflict between the comfortable life nurtured by human society and the raw forces of nature which eventually awaken his ancestral instincts, reshaping him from a domesticated pet into a creature of the wild.
