Answer:
Global trade can have many fundamental effects on countries around the world. International trade results in the rapid development of countries and infrastructure. In addition, global trade can introduce new products and materials to countries, increasing development. This exposes countries to a variety of goods and services that were previously unavailable in their domestic economies. Imports from other countries also tend to lower consumer prices, which has a positive effect on global economies. Overall, global trade is central to the economic development of countries worldwide and positively impacts quality of living.
