A grassroots movement is a type of social or political campaign that starts at the local level, driven by ordinary people rather than established leaders or organizations. These movements often focus on specific issues, such as environmental protection, social justice, or community development, and aim to create change through collective action and community engagement. Grassroots movements typically rely on volunteer efforts, community organizing, and public awareness to gain support. They can utilize various methods, including protests, petitions, and social media campaigns, to mobilize individuals and influence decision-makers, often leading to significant changes in policies or societal attitudes.
