Advocacy Groups for Human Rights and Civil Liberties

Advocacy groups for human rights fight for our various freedoms. They're out there working tirelessly to shine a light on injustices within society, especially for those who often get pushed to the sidelines. Whether they're diving into legal battles, spreading the word to the public, or sharing violations with policymakers, their main goal is pretty simple — making sure everyone gets treated with respect and fairness, no matter who they are or where they come from.

Animal Rights

Animal rights organizations seek to protect animals and their habitats through advocacy as well as action-based and educational initiatives. They rally against cruelty, rescue animals in need, and are known to give a nudge to lawmakers to keep animal rights and welfare in the spotlight.

General Emergency Relief

These organizations step in and provide relief during difficult times, such as natural disasters and war.

Shortly thereafter, she started walking.
