Final answer:
The analogy is completed by equating a natural green environment and a farm with concrete buildings and an urban area. Barns and grain silos on a farm contrast with concrete buildings as symbols of urban development. Both agricultural practices and urbanization have profound effects on the environment.
Step-by-step explanation:
If a natural green environment is to a farm as concrete buildings are to an urban area, we complete the analogy by comparing two distinct types of landscapes. The farm represents the natural, agricultural side of the landscape, often featuring elements such as barns, grain silos, and other structures essential for farming operations. These components not only serve practical functions but also tell a story about the farming practices and history of a region.
In contrast, an urban environment is characterized by its dense concentration of concrete buildings and infrastructure that serve as residential, commercial, and industrial spaces. Just as a green field or a dense forest can be indicators of a natural and agricultural setting, tall concrete buildings are iconic of urbanization and the human-made environment.
Finally, the effects of agricultural practices and urban development on the environment are significant. Livestock farming, for example, is a notable factor in deforestation, affecting habitats, greenhouse gas emissions, and potentially altering rainfall patterns.
