The one-child policy in China, implemented in 1979, aimed to control the overpopulation issue but resulted in severe social and ethical problems, including gender discrimination and forced abortions. The policy has contributed to a significant gender imbalance, with a preference for male children leading to increased instances of female infanticide and trafficking. Critics argue that it violates basic human rights and has created long-term economic challenges, including an aging population and a diminished working-age demographic.
