An NGO, or Non-Governmental Organization, is a nonprofit group that operates independently of government involvement and works toward social, environmental, or humanitarian goals. NGOs play a vital role in addressing issues such as poverty, education, health care, gender equality, disaster relief, and human rights. They are often funded by donations, grants, and volunteer efforts, and they work at local, national, or international levels. By collaborating with communities and stakeholders, NGOs strive to bring sustainable development and positive change to society, especially in underserved or marginalized areas.
