The world's busiest shipping routes are on the Pacific Ocean and the Atlantic Ocean. This is because the Pacific and the Atlantic oceans are the largest and most heavily trafficked bodies of water on the planet, connecting many of the world's major trading nations.
The Pacific Ocean is home to several busy shipping routes, including the Transpacific shipping route, which connects Asia and North America. This route is one of the busiest in the world, as it connects many of the world's largest economies, including China, Japan, and the United States.
Similarly, the Atlantic Ocean is also a major hub for global shipping. The North Atlantic shipping route connects North America and Europe, while the South Atlantic shipping route links South America, Africa, and Europe. The Atlantic Ocean also serves as a major shipping route for oil and natural gas, with many tankers transporting these resources from the Middle East to Europe and North America.
Overall, the Pacific and Atlantic Oceans are key transportation corridors for international trade, and the busiest shipping routes in the world are located in these two oceans.
