NGOs, or non-governmental organizations, play a significant role in global politics by advocating for various issues, providing humanitarian aid, and influencing policy. They often fill gaps left by governments, promote human rights, and mobilize public opinion. NGOs work at local, national, and international levels to address issues such as environmental sustainability, education, and health care, often collaborating with international organizations and governments. Their efforts can lead to significant changes in policy and create enhanced awareness of global challenges, making them vital players in shaping the political landscape and holding authorities accountable.
