Activist groups are organizations formed by people 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. Members work to raise awareness, influence public opinion, and advocate for policies that align with their goals. Many activist groups use various methods to achieve their objectives, including protests, petitions, and educational campaigns. They may also collaborate with other organizations or engage with government officials to push for reforms. By mobilizing communities, activist groups play a crucial role in shaping a better future for society.
