 * Planetary boundaries** is the central concept in an Earth system framework proposed by a group of Earth system and environmental scientists led by Johan Rockström from the Stockholm Resilience Centre and Will Steffen from the Australian National University. In 2009, the group proposed a framework of “planetary boundaries” designed to define a “safe operating space for humanity” for the international community, including governments at all levels, international organizations, civil society, the scientific community and the private sector, as a precondition for sustainable development. - [|Wikipedia]

Nine planetary boundaries 1. Climate change 2. Change in biosphere integrity (biodiversity loss and species extinction) 3. Stratospheric ozone depletion 4. Ocean acidification 5. Biogeochemical flows (phosphorus and nitrogen cycles) 6. Land-system change (for example deforestation) 7. Freshwater use 8. Atmospheric aerosol loading (microscopic particles in the atmosphere that affect climate and living organisms) 9. Introduction of novel entities (e.g. organic pollutants, radioactive materials, nanomaterials, and micro-plastics).
