what is the major conflict

John Arabl's sow has given birth to a litter. Wilber is the runt of the litter and hence not viable to raise for market. Fern John's young daughter pleads with her father to keep him alive. As Wilber grows, the farm animals tell Wilbur that he eventually will be killed. Wilbur attempts to stop this with the help of his spider friend Charlotte. The spider writes words extolling the pig's many virtues. Can Wilbur be saved from the slaughterhouse? Much of it is an external conflict between Wilbur/ animals and society. Are animals worth more than a food source? Does the little girl Fern have a point about rights of animals in a farm? These are pretty much the conflicts but of course it is important to remember that they are presented in the context of a children’s book.
