Today we live in a global community no longer limited by physical boundaries. People across the world are connected by the internet, by communications, by the ease of travel. People, money, information, ideas, services, and goods are constantly moving between countries. This causes cultural and economic changes in the countries involved. This is what we call globalization. As technology has advanced so have the possibilities of international trade and exchange. The increase in international trade has both created and been supported by international regulatory groups like The World Trade Organization and transnational trade agreements like The North American Free Trade Agreement. Anymore there isn't a single country that is completely independent. All are dependent, to some degree, on international trade for their own prosperity. Without international trade there'd be no need for international regulatory groups, and without the international regulatory groups international trade at the current massive scale would be impractical.
