List key categories of man-made resources

Man-made resources are items or substances created by humans, usually from natural resources, to satisfy their needs and wants. They can be broadly categorized as follows:

• Infrastructure: These are the large-scale physical structures that form the foundation of a modern society. This includes transportation networks (roads, bridges, airports, railway lines), utilities (power grids, water supply systems, dams), and communication networks (internet cables, cell towers).
• Technology and Machinery: This category includes all tools, equipment, and systems created to solve problems or improve efficiency. Examples range from simple tools (hammers, plows) to complex machinery (factory robots, computers, medical scanners) and digital systems (software, apps, AI).
• Manufactured Goods: These are the finished products created for consumption or use. This vast category includes electronics (phones, TVs), vehicles (cars, buses), clothing (textiles), and furniture.
• Structures and Buildings: This refers to all man-made constructions for shelter, work, and community. It includes housing (homes, apartments), commercial buildings (offices, stores), and public institutions (schools, hospitals, libraries).
• Processed Materials: These are materials that do not exist in nature in their final form but are created by humans through chemical or physical processes. Prime examples include plastics, steel, glass, paper, and concrete.
