What is the danger of a country that only depending on only one crop?

A country that relies solely on one crop is vulnerable to economic instability and food insecurity due to factors like pests, diseases, and climate change, which can devastate that crop. This lack of diversification can lead to fluctuations in market prices and income, making farmers and the economy susceptible to crises. Additionally, over-reliance on a single crop can deplete soil nutrients and reduce biodiversity, further threatening agricultural sustainability. Ultimately, such dependence can jeopardize the nation's food supply and overall resilience.
