1. Urban areas are characterized by higher population density and infrastructure compared to rural areas. This often leads to increased consumption of resources such as water, electricity, and food.

In the early 20th century, urban populations were significantly smaller. However, urbanization has accelerated, and now a significant portion of the global population resides in urban areas.

What is a likely consequence of continued urbanization?

• 1.  A decrease in global energy consumption.

• 1.  An increase in resource consumption.

• 1.  A reduction in urban infrastructure development.

• 1.  A decrease in urban population density.
