According to CareerExplorer.com, A humanitarian is someone who actively engages in promoting human welfare and social reforms, and who has no prejudice with human suffering on grounds of gender, sexual orientation, religious or national divisions. A humanitarian's goal is to save lives, relieve suffering, and maintain human dignity. This can be done in the form of rescuing and providing safety for refugees, providing shelter and food for the homeless, or helping people in the aftermath of natural disasters or civil unrest.
World Humanitarian Day (WHD) is held every year on 19 August to pay tribute to aid workers who risk their lives in humanitarian service, and to rally support for people affected by crises around the world.
