Option 2 is correct because Wetlands International operates by integrating field-level knowledge and experiences to advocate for improved policies on wetland conservation and sustainable management. Unlike intergovernmental organizations, which are established by formal agreements among governments, Wetlands International is a global non-governmental organization that collaborates with various stakeholders, including local communities, scientists, and policymakers, to enhance wetland health globally. This grassroots approach ensures that their advocacy is grounded in practical, on-the-ground insights, a critical aspect for effective environmental policy-making.
