Answer:<em> </em>In today’s global economy, consumers are used to seeing products from every corner of the world in their local grocery stores and retail shops. These overseas products—or imports—provide more choices to consumers. And because they are usually manufactured more cheaply than any domestically-produced equivalent, imports help consumers manage their strained household budgets. When there are too many imports coming into a country in relation to its exports—which are products shipped from that country to a foreign destination—it can distort a nation’s balance of trade and devalue its currency. The devaluation of a country's currency can have a huge impact on the everyday life of a country's citizens because the value of a currency is one of the biggest determinants of a nation’s economic performance and its gross domestic product (GDP). Maintaining the appropriate balance of imports and exports is crucial for a country. The importing and exporting activity of a country can influence a country's GDP, its exchange rate, and its level of inflation and interest rates.
