This coming year could determine not only whether the world rises to the considerable challenges now facing it—climate change, persistent hunger, increasing inequality, stubborn poverty—but also affecting the fate of generations to come. With a growing population that will exceed 9 billion by 2050, the increasing effects of climate change, a widening gap between rich and poor, and growing competition for resources, the major issues facing humanity cannot wait. Deliberation must give way to deliberate action. But the global political will to eradicate extreme poverty, hunger and malnutrition within a generation, and the conviction that this is achievable, are growing. An ambitious agenda is emerging in the process of identifying post-2015 development goals. It aims to end poverty everywhere in all its forms, and to end hunger and achieve food security. And it plans to do so sustainably. This would perhaps be one of the greatest steps ever taken to secure the future of humanity and the life of the planet.
