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, access to clean water, a good education and much more. Now, 17-year-olds from 17 different countries tell us what they want the world to be doing. Seventeen-year-old Rosa Angelica lives in a Mayan community. As many as 80% of Mayan children in Guatemala suffer from malnutrition. Rosa Angelica has spoken to volunteers, activists and even a government minister to try to find out what Guatemala should be doing if it is to reach the UN Sustainable Development Goal of Zero Hunger by 2030. Project 17 is a unique collaboration between the BBC World Service and the Open University. Presenter: Sana Safi. Producer: Kate Lamble.
