Grassroots movements reflect societal change by mobilizing communities around shared values and goals. These movements often arise in response to feelings of marginalization or injustice, enabling citizens to advocate for change on issues such as social justice, environmental protection, and human rights. By fostering participation and building coalitions, grassroots initiatives challenge established norms and influence policy. They also act as a barometer for public sentiment, highlighting the connection between individual experiences and broader societal trends.
