Resources, Human Environments, and Global Change

Natural Resources and Economic Development

Natural resources include materials and energy sources supplied by nature that people use. These resources fall into two primary categories based on their availability over time. Renewable resources naturally replenish over time, allowing them to regenerate through natural processes. In contrast, nonrenewable resources exist in finite quantities, meaning they do not replenish at a pace that matches human consumption. Fossil fuels such as coal, oil, and natural gas are nonrenewable resources that remain major sources of energy worldwide, powering industries, transportation systems, and electrical grids.

The geographic distribution of natural resources across the Earth is uneven. Because natural elements are not spread out equally, geography directly shapes how human societies grow and prosper. Regions with abundant arable land and freshwater often support substantial agricultural production. Historically, many early civilizations developed along major river valleys, where rivers provided reliable freshwater and fertile soils for growing crops. Similarly, coastal locations and navigable rivers historically lower transportation costs and foster commercial trade hubs, while landlocked nations often face higher transportation costs when trading physical goods globally.

Geographic advantages also influence how societies organize their labor and industries. Economic activities based on the direct extraction of natural resources are classified as primary economic activities. Common examples include farming, timber harvesting, and mining. In contrast, secondary economic activities include manufacturing goods from raw materials and construction, such as making furniture from timber or building structures. Access to mineral wealth can stimulate industrialization and urban infrastructure development, helping a region expand its factories, transportation systems, and cities.

Because no single nation possesses every necessary material, resource scarcity often encourages nations to trade for goods they cannot readily produce domestically. However, relying too heavily on primary extraction creates economic challenges. Heavy reliance on a single natural resource can make an economy vulnerable to global price fluctuations. When the worldwide market price for that specific resource drops, an entire national economy can experience severe disruption.
