Earth's Ecological Danger Zone Threatens Human Survival

Earth has exceeded seven out of eight scientifically established safe limits for life, including climate, air pollution, freshwater safety, and the overall natural and human-built environment, according to a new study by the international scientist group Earth Commission. The study includes measures of "justice," which includes preventing harm to countries, ethnicities, and genders. The planet can recover if it changes, including its use of coal, oil, and natural gas and the way it treats the land and water, the scientists said.
