Why does over reliance on one product weaken an economy?

Overreliance on a single product can weaken an economy by creating vulnerability to market fluctuations, such as price volatility or changes in consumer demand. If the product experiences a downturn, the entire economy can suffer, leading to job losses and reduced investment. Additionally, it stifles innovation and diversification, making it harder for other sectors to develop and thrive. This lack of economic resilience can hinder long-term growth and stability.
