Trade is necessary for a globalised society because trade influences export and import. Trade was used in history as a means for income or to provide. Alliances could’ve been made from good trading chemistry but trade dosen’t really hurt anyone but can sometimes damage or influence the economy. “The Age of Discovery” happened because of the need for trading spices and other good with the East and that’s one of the reasons the Portuguese were leading the age of discovery. Trade even globalises a society or empire.
