Supranational organizations are entities formed by multiple countries that work together to achieve common goals, often transcending national boundaries. These organizations can address issues like trade, security, and environmental protection. Examples include the European Union and the United Nations. These organizations typically have authority that can override national laws, allowing them to implement policies that member states agree upon. This cooperation can lead to more effective solutions for global challenges, such as climate change and economic instability, benefiting all member countries involved.
