The most important invention

There are a lot of convenient things such as cars, airplanes, ships, refrigerators, TV, phone, air conditioners, computers, washing machines in present-day life. We men of today consider them ordinary because they are near to ourselves. These inventions are very convenient and important but I think that ships are the most important invention of all. First, we can transport large quantities of loads. Each different country trades. Trade is necessary. Japan particularly needs to import food because food self-sufficient rate in Japan is row. Ships are useful to transport big and heavy things such as cars too. If we use airplanes, we can transport quickly but we can’t use them to transport lots of big and heavy things, so ships are the best way to trade. Second, long-distance transport is possible. When there were no ships, people walked and rode hoses to move from place to place and they could not cross over the sea. That’s why people only knew their different land, a part of earth. It takes a long time to sail but ships can stop countries and islands easier than airplanes. Third, human history was produced by development ships. This is the most important point. Judging by the history, human beings have used ships since long time ago. On and after being invented first ships, human beings use them in various cases. For trade, war, voyage, emigration and so on. Without ships, human society could not development. These are the reasons why I think ships are the most important invention.
