What did Greece lack?

Some of the key resources that Greece lacked included:

* Arable land: Greece is a mountainous country with a limited amount of arable land. This made it difficult for the Greeks to grow enough food to feed their population.

* Water: Greece is also a relatively dry country, and water shortages were a common problem. This made it difficult for the Greeks to irrigate their crops and maintain a healthy agricultural sector.

* Timber: Greece lacked large forests, which made it difficult for the Greeks to build ships, construct buildings, and produce other goods made from wood.

* Minerals: Greece had some mineral resources, such as iron and copper, but these were not in sufficient quantities to support a large-scale industrial economy.

These resource shortages made it difficult for Greece to compete with other countries in the region, and they were a contributing factor to the decline of the Greek economy in the 4th century BC.
