A new report from the Intergovernmental Platform for Science and Policy on Biodiversity and Ecosystem Services (IPBES), the most complete ever completed in its genre, and based on the Millennium Ecosystem Assessment of 2005, suggests that one million species of animals and plants are now endangered, many within decades.
The report has been compiled by 145 expert authors from 50 countries in the last three years, with contributions from another 310 contributing authors.
According to data from the report, more than 40% of amphibian species, almost 33% of re-forming corals and more than a third of all marine mammals are threatened, in addition to an estimate of about 10% of all insects.
The culprits, according to the report, are the following, in descending order:
- Changes in the use of land and sea.
- Direct exploitation of organisms.
- Climate change.
- Invasive alien species.
Three quarters of the earth's environment and about 66% of the marine environment have been significantly altered by human actions, and more than a third of the world's land area and almost 75% of freshwater resources are now dedicated to agricultural or livestock production.
Negative trends in nature will continue until 2050 and beyond in all policy scenarios explored in the Report..
