International trade can provide benefits but also disadvantages. It allows countries to specialize in what they produce most efficiently while gaining access to a wider variety of goods. However, it can also lead to economic dependence on other nations and depletion of natural resources if not properly managed. Traders act as intermediaries, moving goods from producers to wholesalers to retailers and finally consumers. Goods are traded within a country as internal trade or across borders as international trade through imports and exports.
