Ships are developed with the development of human beings. Whether in wartime or in peacetime, there are ships. Millions of fishermen around the world use fishing boats to catch fish. Wartime naval warfare and maritime munitions are all related to ships.
In 2007, there were about 35,000 merchant ships carrying 7.4 million tons of cargo. By 20 1 1 year, about 104304 ships in the world have obtained IMO numbers issued by IMO.
Historically, ships have played an important role in geographical exploration and scientific and technological development. Like Zheng He of the Ming Dynasty in China, he spread the compass and gunpowder to other areas.
Ships can be used for colonial and slave trade purposes, as well as for science, culture and humanitarianism. The Columbus exchange between America and Europe was one of the main reasons for the world population growth at that time. Shipping also makes the world economy an energy-intensive economy.
