International organizations address global challenges by facilitating cooperation among member countries, providing platforms for dialogue, and coordinating responses to issues like climate change, health pandemics, and security threats. Organizations such as the United Nations, World Health Organization, and World Trade Organization establish norms, frameworks, and agreements that guide international behavior. They play a crucial role in providing humanitarian assistance, fostering development, and addressing transnational issues effectively. Their collaborative efforts are essential for global stability and progress in various sectors, including health, trade, and conflict resolution.
