A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. [1] [2] ...
Biodiversity hotspots across the world Several international organizations focus their conservation work on areas designated as biodiversity hotspots . According to Conservation International , to qualify as a biodiversity hotspot a region must meet two strict criteria:
Hotspot ecosystems support high species diversity, numbers of individuals, or both, and are therefore important in maintaining margin-wide biodiversity and abundance. [9] HERMIONE research ranges from investigation of the ecosystems' dimensions, distribution, interconnection and functioning, to understanding the potential impacts of climate ...
Biocultural diversity is defined by Luisa Maffi, co-founder and director of Terralingua, as "the diversity of life in all its manifestations: biological, cultural, and linguistic — which are interrelated (and possibly coevolved) within a complex socio-ecological adaptive system."
The latter is often true of species living in biodiversity hotspots, which are areas of the world with an exceptionally high concentration of endemic species (species found nowhere else in the world). [48] Many of these hotspots are in the tropics, mainly tropical forests like the Amazon. [49]
Most of the exponential human population growth worldwide is occurring in or close to biodiversity hotspots. [6] This may explain why human population density accounts for 87.9% of the variation in numbers of threatened species across 114 countries, providing indisputable evidence that people play the largest role in decreasing biodiversity.

Environmental sociology is the study of interactions between societies and their natural environment.The field emphasizes the social factors that influence environmental resource management and cause environmental issues, the processes by which these environmental problems are socially constructed and define as social issues, and societal responses to these problems.
Megadiversity means exhibiting great biodiversity. The main criterion for megadiverse countries is endemism at the level of species, genera and families. A megadiverse country must have at least 5,000 species of endemic plants and must border marine ecosystems.
