Biodiversity is declining as we impact the planet and all species with the burden of our expansion.

IUCN stands for International Union for Conservation of Nature.
It is the global authority on the status of the natural world and the measures needed to safeguard it. Its experts are organized into six commissions dedicated to species survival, environmental law, protected areas, social and economic policy, ecosystem management, and education and communication.
The IUCN Red List relies on assessors (trained individuals, usually species experts) to assess species based on the currently available data and information. This comes from a range of sources, including published scientific papers, books, reports, expert knowledge, indigenous knowledge and citizen science.
IUCN informs on the status of the existing wildlife in 9 Red List Categories:
Extinct
Extinct in the Wild
Critically Endangered (Threatened with extinction)
Endangered (Threatened with extinction)
Vulnerable
Near Threatened
Least Concern
Data Deficient
