I believe that the creators of the Utopia got rid of sunshine due to people getting sunburnt. In "The Giver", the Old Man recalls, "'It was sunburn," the old man told him. 'It hurt a lot,' Jonas said." This quote means that sunshine can hurt someone with fair skin, thus I think the creators took sunshine out so that no one would feel the pain of sunshine. Also, sunshine, if out for too long, can cause skin cancer, and no one would want that. ~Lindsey Rogowicz
