In this blog post, we examine the rise and fall of the ancient city of Ephesus to explore the consequences of humanity’s choices that ignored nature.
Examples of how the use of nature has led to disaster have existed since the early days of human history. While humans have utilized nature to develop civilization, they have often underestimated its power or misused it in ways that have led to unforeseen disasters. The Mediterranean coast was once home to various civilizations, including ancient Greece and Rome. Thanks to its fertile soil and mild climate, agriculture and maritime trade flourished in this region, laying the foundation for the development of cities and the blossoming of civilization. However, looking at the Mediterranean coast today, it is hard to believe that this was once the site of the most advanced civilizations. The landscape of the Mediterranean has undergone many changes over time, resulting in the decline or disappearance of many cities. Among them, Ephesus was a famous maritime city that flourished during the Roman Empire. Ephesus is a prime example of the prosperity of that era, with Roman-era buildings and ruins scattered throughout the city, giving a glimpse of its former grandeur. However, today, only the remains of a massive amphitheater, marble columns, and exquisite sculptures are scattered across the city, now reduced to ruins. This raises the question of how a city that once flourished on the abundance of nature could become so desolate. What caused Ephesus to decline so rapidly?
The exact cause remains unclear, but it is speculated that it may have been due to changes in the ecosystem. Scholars studying the rise and fall of ancient cities emphasize the close relationship between the natural environment and human activity, citing Ephesus as an example. Changes in the ecosystem can be inferred by examining the flora that thrived at the time. Pollen from plants does not decompose easily and is preserved in the soil for a very long time. Therefore, analyzing pollen found in soil layers can reveal not only the flora and climate of the time but also the form of agriculture and social conditions. Such research provides important clues for understanding the causes of the decline of ancient cities. Analysis of pollen collected from soil in Ephesus revealed that wheat pollen dominated the soil layers from 2,000 years ago, when Ephesus was at its peak. This indicates that wheat-based field agriculture was prevalent. Wheat was the staple food of the people at that time, and agricultural activities related to its cultivation significantly influenced the city’s economy and social structure. In older layers, pollen from grasses typically found in grasslands was discovered in large quantities. In layers dating back 4,000 years, when the area was uninhabited, pollen from oak trees was found in large amounts.
This indicates that the environment of Ephesus changed from a forest area to a grassland area and then to an agricultural area. In other words, as people gathered, the agricultural area expanded, and the forest area gradually decreased. Forests play a very important role in the water cycle. Dense forests have fallen leaves and topsoil, which can store large amounts of water.
This stored water evaporates to form clouds, which then return to the forest as rain. In this way, the natural cycle is closely interconnected, and any change in one element can have a chain reaction on others. However, as civilization flourished in Ephesus, the forests diminished, disrupting the water cycle and leading to reduced rainfall. As the climate became drier and the land grew increasingly barren, Ephesus suffered repeated famines, and the once-prosperous civilization began to crumble. Additionally, the topsoil of the barren mountains was washed away by rainwater, gradually filling the sea, causing Ephesus’ trade to decline and eventually losing its function as a maritime city. Ultimately, the city was abandoned and left in ruins.
This case offers an important lesson for us today. Unrestricted exploitation of nature inevitably leads to consequences. History has repeatedly warned us against the arrogance of believing that humans can conquer nature. For sustainable development, we must find ways to live in harmony with nature; otherwise, cases like Ephesus will repeat themselves.
