In September 2015 World Leaders at the United Nations committed to the Global Goals for Sustainable Development. 17 goals to achieve 3 extraordinary things in the next 15 years. End extreme poverty. Fight inequality and injustice. Fix climate change. To realise these Goals everyone, however young they are, needs to take part. The World’s Largest Lesson is an initiative to introduce students in schools to the UN Global Goals and encourage them to support them and to take part in their achievement.
