The oil industry had the biggest impact on what other industry?

The oil industry had the biggest impact on the transportation industry. The discovery and refining of petroleum products fueled the development of automobiles, airplanes, and ships, revolutionizing how goods and people are moved around the world. This transformation not only accelerated global trade and travel but also led to the expansion of infrastructure, such as roads and airports, that further entrenched fossil fuels as a dominant energy source.
