I believe the biggest global social challenge today is inequality in access to basic needs like education, health care, and clean water. Many people in poor communities cannot go to school or see a doctor, which limits their future opportunities. For example, in some rural areas, children must walk long distances to reach a school or a hospital, causing many to drop out. This problem affects not only individuals but also whole societies, because without equal access, countries cannot develop fairly. Solving this challenge requires cooperation from governments, communities, and international organizations.
