Which is at the highest rate of extinction?
End Permian (252 million years ago): Earth’s largest extinction event, decimating most marine species such as all trilobites, plus insects and other terrestrial animals.

Where on earth are most extinctions currently occurring?
Micronesia and Polynesia. Called the “epicenter of the current global extinction,” by Conservation International, this smattering of more than 4,000 South Pacific islands is at risk from both local human activity and global climate change. Humans settled on these islands between 2,000 and 3,000 years ago.
Which country is rich in wildlife?
Brazil is the Earth’s biodiversity champion. Between the Amazon rainforest and Mata Atlantica forest, the woody savana-like cerrado, the massive inland swamp known as the Pantanal, and a range of other terrestrial and aquatic ecosystems, Brazil leads the world in plant and amphibian species counts.
What was the first animal to go extinct due to humans?
the dodo
With their penchant for hunting, habitat destruction and the release of invasive species, humans undid millions of years of evolution, and swiftly removed this bird from the face of the Earth. Since then, the dodo has nestled itself in our conscience as the first prominent example of human-driven extinction.
What is the most endangered species in America?
Here are some of the USA’s most endangered species
- Florida panther. The panther is one of the most endangered mammals in the country, according to the Defenders of Wildlife.
- Lesser prairie chicken.
- Devil’s Hole pupfish.
- Bryde’s whale.
- North Atlantic right whale.
- Monarch butterfly.
- Delta Smelt.
What states have the least endangered species?
As of July 2016, there were 1,353 endangered and threatened animal species listed in the 50 states (this did not include species in U.S. territories and included species listed in more than one state). California contained the most animal species (122) while Vermont contained the fewest (3).
Why are extinction rates so high in the world?
It’s also because we often simply don’t know what is happening beyond the world of vertebrate animals that make up perhaps 1 percent of known species. One recent report noted that current extinctions were ‘up to 100 times higher than the background rate.’ One way to fill the gap is by extrapolating from the known to the unknown.
How many species are at risk of extinction in the US?
The United States is home to 1,278 species at risk of extinction — the second-highest count worldwide — according to the latest update of the International Union for Conservation of Nature’s Red List of Threatened Species.
Why are the majority of extinctions on small islands?
Moreover, the majority of documented extinctions have been on small islands, where species with small gene pools have usually succumbed to human hunters. That may be an ecological tragedy for the islands concerned, but most species live in continental areas and, ecologists agree, are unlikely to prove so vulnerable.
Why are amphibians most at risk of extinction?
That is 27 % of all species assessed. Amphibians are under the highest threat but all groups of species are at risk. Global mass extinction could further accelerate by 2100 because of global warming caused by increased levels of CO2 in the atmosphere.
