Why did many people in Ancient Greece make there living from the sea?

Many people in Ancient Greece made their living from the sea due to the region's geography, which featured numerous islands and a rugged coastline that facilitated maritime activities. The Mediterranean Sea provided abundant resources, such as fish and trade routes, essential for the economy. Additionally, seafaring allowed for trade with other cultures, enhancing access to goods and resources not available locally. This reliance on the sea was crucial for survival and prosperity in a landscape with limited arable land.
