Advocacy groups are organizations that work to promote specific causes or issues, often aiming to influence public policy and raise awareness. These groups can focus on a wide range of topics, including environmental protection, human rights, healthcare reform, and education. They often engage in activities such as lobbying government officials, organizing campaigns, and conducting research to support their goals. Members of advocacy groups may include concerned citizens, experts, and activists who share a common interest in the cause. By collaborating and mobilizing resources, these groups strive to create positive change in society and ensure that the voices of their constituents are heard.
