Answer:
The Petroleum Industry is massive.
Explanation:
The main reason it is massive is because Petroleum/Oil is located all across the world. Oil/Petroleum attracts attention. In the Middle East, you got Kuwait, Saudi Arabia, Iraq, Iran, and many more. In North America, you have Canada. And in South America, you have Venezuela. The main reason Iraq invaded Kuwait back in 1990 was because Saddam Hussein wanted to take the oil in Kuwait. America had to protect Kuwait due to the fact it attracts attention.
