The assessment found that crabs, crayfish and shrimps face the highest extinction risk of the groups studied, with 30% under threat, followed by 26% of freshwater fish species, and 16% of ...
With regards to climate change, the experts estimated that 2 °C (3.6 °F) threatens or drives to extinction about 25% of the species, although their estimates ranged from 15% to 40%. When asked about 5 °C (9.0 °F) warming, they believed it would threaten or drive into extinction 50% of the species, with the range between 32 and 70%. [45]
Endangered species are addressed through Canada's Species at Risk Act. A species is deemed threatened or endangered when it is on the verge of extinction or extirpation. Once a species is deemed threatened or endangered, the Act requires that a recovery plan to be developed that indicates how to stop or reverse the species' population decline. [33]
Both climate warming and cooling can cause range shifts and local extinction of animals, but quantitative evidence is rare due to the lack of long-term spatial-temporal data. In [47] Extreme temperature change was negatively associated with increased local extinction of mammals such as the gibbon, macaque, tiger, and water deer. Researchers ...
All three animals, seemingly unrelated, all have one thing in common. Each is critically endangered, according to the World Wildlife Fund. The International Union for Conservation of Nature lists ...
If humans don't start doing more to protect the environment we could see 16 percent of the Earth's wildlife go extinct, according to a new study. The research published Thursday in the journal ...
The World's 100 most threatened species [1] is a compilation of the most threatened animals, plants, and fungi in the world. It was the result of a collaboration between over 8,000 scientists from the International Union for Conservation of Nature Species Survival Commission (IUCN SSC), along with the Zoological Society of London .

Invasive species invade and exploit a new habitat for its natural resources as a method to outcompete the native organisms, eventually taking over the habitat. This can lead to either the native species' extinction or causing them to become endangered, which also eventually causes extinction. Plants and animals may also go extinct due to disease.
