Good health. Clean water. Zero hunger. Quality education. Decent work. No poverty. Millions of us take these privileges and rights for granted. For billions more, they remain elusive dreams. These and the other United Nations Sustainable Development Goals (SDGs) - 17 in all - form the heart of Agenda 2030, which promises peace and prosperity for people and the planet. Collectively they represent an urgent call to action all world citizens must heed before it’s too late.
