In 2015, the 193 countries of the United Nations agreed on seventeen Sustainable Development Goals. These goals are very important because they tell us what we must do to end the world’s biggest problems, like poverty, hunger, and climate change. This book explains each of the goals and gives examples of the wonderful work that is already happening around the world to end these big problems. It also gives great ideas of changes that we can all make in our own lives. We must all work together, to build a better world for everyone!
