Humanity is the greatest religion of them all and Sikhs are a testament to this fact. Sikhism has its roots in selfless service, and time and again, people from this community have reiterated this fact. Ravi Singh, a British Sikh of Indian origin, is a living example of this. Through his humanitarian work in the world's most dangerous territories, Singh is making a difference in the lives of war victims.

To give you a little background, Yazidis are one of Iraq's oldest yet neglected minority communities. When ISIS captured northern Iraq, they killed their men and took their women into sexual slavery. Those who escaped were forced to flee their ancestral homes and take refuge in the Sinjar Mountains without food or water.

And this is where the 47-year-old Ravi Singh comes in. Singh is a ray of hope for all the 400 refugee families, who not only wait for ration but also the positivity that Singh brings into their lives, making them feel cared for.
