The report estimates that there are 8 million animal and plant species on Earth, with the majority (5.5 million) represented by insects. Out of those 8 million species, 1 million are threatened with extinction , including 40 percent of amphibians , almost a third of reef -building corals , more than a third of marine mammals , and 10 percent of ...
The World Wildlife Fund’s Living Planet Report 2022 found that wildlife populations declined by an average 69% since 1970. [1] [2] [3]The Living Planet Index (LPI) is an indicator of the state of global biological diversity, based on trends in vertebrate populations of species from around the world.
The world’s frogs, salamanders, newts and other amphibians remain in serious trouble. A new global assessment has found that 41% of amphibian species that scientists have studied are threatened ...
Insects make up the vast majority of animal species. [14]Chapman, 2005 and 2009 [9] has attempted to compile perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature.
Many [quantify] people value the complexity of the natural world and express concern at the loss of natural habitats and of animal or plant species worldwide. [ 53 ] Probably the most profound impact that habitat destruction has on people is the loss of many valuable ecosystem services .
To qualify as a biodiversity hotspot on Myers' 2000 edition of the hotspot map, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (more than 0.5% of the world's total) as endemics, and it has to have lost at least 70% of its primary vegetation. [6] Globally, 36 zones qualify under this definition. [7]
To date, at least 40,000 plant species, [50] 2,200 fishes, [51] 1,294 birds, 427 mammals, 428 amphibians, and 378 reptiles have been scientifically classified in the region. [52] One in five of all bird species are found in the Amazon rainforest, and one in five of the fish species live in Amazonian rivers and streams.
