In 2015 the United Nations announced a radical plan to change the world.

Global leaders drew up a list of 17 "sustainable development goals" to create a blueprint for a better future. Governments agreed to support the goals which cover gender equality, health provision, a good education and much more. We've asked 17-year-olds from 17 different countries tell us what they think needs to change if the world is to meet those goals by 2030.

Singapore imports 90% of its food and 744,000 tonnes of this ends up as food waste. Seventeen-year-old Shan wants to find out what might be some of the solutions.

"I really had my eyes opened to just the sheer scale of food wastage within Singapore. I hope that this can serve as a symbol and an inspiration for young people and for everyone out there to play their part and contribute as well as they can to tackling issues related to sustainability for a better tomorrow and for a better future for all of us."
