Why Explore the Oceans

The Earth has one big ocean with many features that I have probably learned more about in the past week than I have in a long time. We talked about the explorers and civilizations from many years ago and about how they depended on sea exploration to maintain and grow their knowledge on what the ocean is and what it holds. Every civilization explored for the about all the same reason, which was to find food resources, find land, and find trade routes. Sea exploration does not just date back to Columbus and the other explorers around his time but it goes back to the ancient civilizations like the Phoenicians, Polynesians, Chinese, and the Vikings to name a few.
We all were given an explorer, civilization, or person that invented something to change how we explore the ocean. I was given Ptolemy a man during the Roman Empire, in Egypt who changed the old latitude, longitude system into the same one we use today. The others in my class presented people like Magellan, Columbus, the Chinese, and many more. They told us things I never exactly knew before, like that nobody thought the world was flat, the Chinese were far more advanced than any civilization and they invented the compass. All of these people helped expand the world.
