Grassroots advocacy and lobbying differ fundamentally in their approaches to influence policy. Grassroots advocacy often involves mobilizing community members to advocate for change, focusing on building popular support and raising public awareness. It emphasizes broad participation and may encompass various methods, including protests and community organizing. In contrast, lobbying typically involves direct engagement with policymakers and legislators, often through specialized organizations aiming to influence specific legislation. While both pursuits aim to shape public policy, grassroots advocacy seeks to empower citizens at the community level, while lobbying is generally more formal and institutionalized.
