How many ecosystems of the earth are there? A study published in 2022 in the magazine Nature He counted and classified the ecosystems of the entire planet for the first time.
The initiative was born from the need to preserve the biodiversity of the various environments, and is the result of the collaboration between researchers of the Unsw SydneyInternational Uninone for the conservation of nature (IUcn), the Plus Alliance and over 100 scientists from all over the world.
The researchers developed one Complete ranking of world ecosystems through the mapping of the various environments. In 2020 the first version was presented then perfected over the years to date. This ranking identifies, defines and describes the various ecosystems of the planet, from those already known to those still unknown. The aim is first of all to preserve the biodiversity of our planet, identify the ecosystems threatened by the climatic crisis, to plan prevention and restoration interventions, taking into account the changes to which the terrestrial environments are subject over time.
About the 10% ecosystems has been created and continues to be artificially maintained by man, even if it occupies more than 30%; the remainder 90% Instead it is threatened by the consequences of the climatic crisis.
This overview of ecosystems represents a valid tool for industries and political organizations in order to plan any initiatives in the area. For NGO Instead, it is an incentive to work for the protection of ecosystems, where necessary.
This type of global ecosystem includes not only environments known as tropical forests, large rivers and coral reefs. But also deep oceans, submarine mountains, lakes and microscopic ecosystems in the rocks, generally not known to most.
The researchers divided this ranking according to one hierarchical structure very precise: the highest level divides the planet into the various main kingdomswhile second and third levels include approximately 25 Biomi And 110 functional groups of the ecosystem.
The work of scientists, however, is not finished: the next step is to establish global monitoring, using even more precise and detailed ecosystems maps.
