Trade is the process of exchanging goods and services between people or countries. For example, when a farmer sells fruits at a market, they are trading their produce for money. This exchange allows people to get what they need without having to produce everything themselves. In a global context, countries engage in international trade to obtain resources they lack. For instance, a country rich in oil might trade it for technology from another country. This cooperation helps economies grow and provides consumers with a wider variety of products to choose from.
