Planetary Boundaries

Planetary Boundaries is a concept that describes the environmental limits that humanity should not exceed in order to ensure a safe and sustainable future. The concept was developed by a group of scientists in 2009, and it has since been widely adopted by governments, businesses, and other organizations around the world.

What are the Planetary Boundaries?

The Planetary Boundaries are a set of nine environmental limits that have been identified as critical for maintaining a safe and sustainable planet. These boundaries include:

• Climate Change: The increase in global average temperature should not exceed 2 degrees Celsius above pre-industrial levels.
• Loss of Biodiversity: The rate of species extinction should not exceed 100 times the background rate.
• Nitrogen and Phosphorus Pollution: The inputs of nitrogen and phosphorus to the environment should not exceed a certain level.
• Freshwater Use: The use of freshwater should not exceed a certain level.
• Land-System Change: The conversion of natural land to agriculture or other human uses should not exceed a certain level.
• Ocean Acidification: The acidity of the oceans should not exceed a certain level.
• Aerosol Loading: The amount of aerosols in the atmosphere should not exceed a certain level.
• Chemical Pollution: The release of toxic chemicals into the environment should not exceed a certain level.
• Ozone Depletion: The depletion of the ozone layer should not exceed a certain level.
