Our world faces environmental crises that threaten to upend life as we know it. Earth is degraded, deforested and warming dangerously. Nature and the myriad of benefits that it provides to people is declining all around the world. Poor people and traditional societies, especially in rural areas of developing countries, are particularly vulnerable to its loss. Sustaining and restoring nature is an urgent necessity. It is also common sense. Healthy ecosystems provide our food and water and underpin our prosperity and well-being. Ecosystems shield us from hunger, drought, disease and climate catastrophe. Furthermore, they are key to realizing the rights and hopes of people everywhere to live a good life, protect their culture and lay a firm foundation for future generations. We should work with nature—not against it—to continue to enjoy its benefits and ensure a healthy future for us all. Our growing understanding of how the planet works means that we also know how to fix it. But transforming our relationship with nature requires big changes, including in government policies, the production and consumption of goods and services, and individual behaviour. This practical guide presents some of the most important actions that individuals and organizations can take to collectively achieve the goal to transform our relationship with nature.
