This episode explores the high-stakes world of petroleum extraction and quarrying. We examine how oil and gas are drilled—from deep-sea rigs to desert wells—and the massive machinery behind these operations. You'll learn how quarrying fits into the broader extractive sector, and how the petroleum industry operates very differently across developed and underdeveloped nations. From cutting-edge offshore platforms to communities with few environmental safeguards, we discuss the technological, economic, and ethical contrasts that shape the global energy landscape.
