Pupils at Our Lady Queen of the Apostles Clonburris National School in Clondalkin, Dublin chanted “stop wasting food” and held placards with demands like “don't let me decompose.”
The primary school, where Dublin GAA manager Jim Gavin is a former pupil, took part in the Hunger Heroes campaign run by aid agency Concern Worldwide, which raises awareness of the global hunger crisis and teaches children how they can help solve it.
Schools across the country are urged to join the campaign and to mark Hunger Heroes Day on Friday, October 27 - when students can leave their uniforms at home and go to school in fun costumes while learning how they can help the 815 million people in the world who do not have enough food to eat.
The stark figure, which amounts to 11 per cent of the world’s population, was revealed by the United Nations just last week and is up 38 million from the 777 million people estimated to be chronically undernourished in 2015.
Concern Worldwide said 30 per cent of all food in the world (1.3 billion tonnes) is being wasted, which it said would be enough to feed all the world's hungry four times over.
In Ireland, it is estimated that one million tonnes of food is let go to waste and that this costs each household an average of €700 a year.
“It’s not very nice to waste food,” said Katie Gallagher (6), who was one of the children who took part in Hunger Heroes at Clonburris National School in Clondalkin.
Katie also pointed out that people who waste food risk creating a pungent stench in their own home when she explained: “That means you are going to have a very bad smell in your house.”
