When was there a demand for raw materials?

Demand for raw materials has fluctuated throughout history, often driven by industrialization, economic growth, and technological advancements. Notably, the Industrial Revolution in the 18th and 19th centuries saw a significant surge in demand for materials like coal, iron, and cotton. More recently, the global economic expansion in the early 21st century, particularly in emerging markets, has led to increased demand for various raw materials, including metals and energy resources. This trend continues as industries evolve and the world shifts towards sustainable practices.
