Global challenges need global solutions and global citizens to bring them about. The environmental movement has been in existence for decades, and many people have been working in NGOs and at all levels of government and society on global issues, Even so, over time, the scale of challenges facing the world has continued to grow and the situation has fundamentally grown worse in most areas, such as loss of habitat, biodiversity loss, pollution, climate change, income inequality, the unsustainable use of natural resources, etc. The need has grown for action on these issues which is no constrained by short-term thinking or the limited self-interest of an individual, company, or nation.
