The clothes you're wearing, the phone in your pocket, the chocolate you ate this week all arrived after crossing borders, sometimes several times over. Global exchange is the web of relationships, rules, and infrastructure that lets people, goods, money, and ideas move between countries. It is one way societies meet their needs, share knowledge, and build culture together.
In this subtopic, you'll explore how this web works as a system, with its own parts, relationships, and emergent patterns. You'll trace how global exchange has changed over thousands of years, shaped by shifts in technology, power, and the environment. You'll look at what actually moves across borders: goods and services, people, money, information, energy, and waste. And you will examine the role that multinational corporations and global supply chains play in organising global exchanges.
You'll also think about the distribution of benefits and costs. A decision made by a company or state in one place can affect workers, communities, and ecosystems somewhere else entirely, often without them having any say in it. By looking at how global exchange has developed and who holds power within it today, you'll begin to understand what responsibility might mean when our everyday choices are connected to people and places far beyond where we live.
At the end of Subtopic 7.1 What is global exchange? you should be able to:
describe global exchange as a system with parts, relationships, functions and emergence
describe how global exchange systems have evolved over time, shaped by changes in technology, power, and environmental factors
describe what flows across borders in the global economy
explain how visible global flows are linked to less visible social and ecological impacts
explain the significance of multinational corporations and global supply chains for how economic activity is organised across countries
outline how a country or region's production, policy, financial and consumer decisions impact people and places elsewhere, and what that means for responsibilities
