Nonprofit advocacy groups are organizations that work to promote specific causes or issues, often related to social, environmental, or political matters. They aim to influence public policy, raise awareness, and mobilize community support. These groups operate without the goal of making a profit, relying instead on donations, grants, and volunteer efforts to fund their activities. These organizations often engage in activities such as lobbying government officials, conducting research, and organizing campaigns to educate the public. Examples of nonprofit advocacy groups include the American Civil Liberties Union (ACLU) and Greenpeace, which focus on civil rights and environmental protection, respectively.
