International organizations address global issues through cooperation and collective action aimed at solving problems that transcend national borders, such as climate change, human rights, and public health crises. Organizations like the United Nations and the World Health Organization facilitate dialogue among member states, develop international norms, and provide resources for implementation. They coordinate efforts, share best practices, and mobilize support for collective initiatives. These organizations play a crucial role in fostering multilateralism and enhancing global governance to tackle pressing challenges.
