What is a self-sufficient country?

A self-sufficient country is one that can meet its own needs without relying heavily on external resources or imports. This includes producing its own food, energy, and essential goods, thereby maintaining economic independence and stability. Such countries often focus on sustainable practices, local industries, and resource management to enhance resilience against global market fluctuations. However, complete self-sufficiency is rare, as most nations participate in global trade to access resources or goods not readily available domestically.
