Activist groups are organizations formed by individuals who come together to promote social, political, or environmental change. These groups often focus on specific issues, such as climate change, human rights, or animal welfare, and work to raise awareness, influence public policy, and mobilize community action. Members of activist groups may engage in various activities, including organizing protests, conducting research, and lobbying government officials. They often use social media and other communication tools to spread their message and connect with supporters. Through their efforts, activist groups aim to create a more just and equitable society.
