Final answer:
The uneven distribution of copper affects local economies by providing economic activity and employment opportunities in mining regions, but can also create unstable economic conditions due to fluctuating commodity prices and hinder transportation and export due to their distance from major seaports.
Step-by-step explanation:
The uneven distribution of copper affects local economies in several ways. Firstly, areas with abundant copper reserves, such as the Copper Belt, experience economic activity and employment opportunities due to mining. However, these regions are often far from major seaports, which can hinder export and transportation. Secondly, the fluctuation in world commodity prices can create unstable economic conditions for the mining industry, which may impact the local economy negatively. Lastly, countries heavily dependent on the mining industry, like those with large urban populations, can experience economic consequences when copper prices fluctuate.
