Our political, social and commercial decisions are driving the climate and health crisis. Over 90% of people breathe unhealthy air resulting from burning of fossil fuels. A heating world is seeing mosquitos spread diseases farther and faster than ever before. Extreme weather events, land degradation and water scarcity are displacing people and affecting their health. Pollution and plastics are found at the bottom of our deepest oceans, the highest mountains, and have made their way into our food chain. Systems that produce highly processed, unhealthy foods and beverages are driving a wave of obesity, increasing cancer and heart disease while generating a third of global greenhouse gas emissions.
