Remember the last time you encountered a child at a traffic light or at the corner of a street with his/her stomach ballooned because of malnutrition? When a little kid or a mother holding a child or a poor old boy knocks on the window of our car, we somehow retire into the plush leather sofa, roll the window up and turn up the volume of our stereo system - some of us have successfully taught ourselves how to shut out what needs attention and conveniently. But there are some people who are working hard continuously for the relief of humanity - happily serving without complaining or roaring for attention - from post-earthquake Nepal to serving the homeless poor in the UK, food services offered by Sikh temples are committed strongly to alleviating world hunger and reducing food waste. We hardly took notice of it, isn't it?

Two Sikh organisations in New Delhi and Amritsar sent food relief to victims in post-earthquake Nepal

Besides sending their team of people who served hot meals to over 10,000 people a day, these two Sikh organisations sent out 25,000 packets to Kathmandu.

In the UK, homeless people are getting free meals, all thanks to the centuries-old Sikh tradition

The Sikhs have managed to take the concept of Langar outside its traditional setting in temples and out onto the streets to feed the homeless and the poor. The Guru Singh Sabha Gurdwara in Southall, the biggest Sikh temple outside of India, alone serves 5,000 meals on weekdays and 10,000 meals on weekends.

These community kitchens fed 346,992 people across Britain in the UK last year, according to the Trussell Trust.
