In Chapter 11 of The Giver by Lois Lowry, what is the community's solution to snow and hills?

Jonas's first memory is about sledding down a snowy hill. He absolutely loves the experience and asks the Giver why they don't have snow or hills in their community. The Giver tells him that snow and hills were sacrificed when the community decided to live with Climate Control. He explains that snow and winter slowed down the agricultural growing periods, which influenced the production of food. Snow, winter, and "unpredictable weather" caused problems with transportation, too. Hills were disruptive to the process of getting food out to people, so those were done away with when they went to "Sameness" (84). Sameness is what makes it possible to have a Receiver. Sameness is what gave the community the ability to live in a way that erased suffering and pain from citizens. With each sacrifice, such as hills and snow, the community receives something in return. By sacrificing hills and snow, the community gained more effective transportation, longer agricultural growing periods, and control over the weather.
