The charity aims to raise awareness of the amount of children working on landfill sites and came about after celebrity journalist Amy Hanson spent time in Cambodia in 2008.  

Amy said of the project's aims: "Ideally we want to raise enough money to get the children away from the rubbish dumps and into schools, but for now we're focusing on providing durable boots to prevent the children from harming themselves with the shards of glass and sharp objects on the ground."

Amy is now hoping the auction will raise money to help youngsters in the third-world stay away from rubbish dumps without adequate footwear or off of them entirely.
