How many endangered species are there in the world

The numbers to the right of each bar represent the total number of extant species assessed for each group. Tables 1 and 2 are organized by taxonomic group and show numbers of threatened species listed in the current version of The IUCN Red List in relation to the estimated number of described species Table 1a , and numbers of threatened species in each version of The IUCN Red List since Tables 1b and 2. These tables highlight the disparity between the number of described species and the number of species that have been assessed.

They also provide a summary of overall changes in numbers of threatened species on The IUCN Red List over the last twenty years, however please note that there are many different reasons for these figures changing between different versions of The IUCN Red List see A Dynamic Red List: reasons for changing status above.

Table 1a - Number of species evaluated in relation to the overall number of described species, and numbers of threatened species by major groups of organisms. Table 1b - Numbers of threatened species by major groups of organisms — Tables 3 and 4 are organized by taxonomic group. These should be used to see, for example, the numbers of globally threatened mammals, birds and amphibians Table 4 is an expanded version of Table 3. Combining the total numbers of EX and EW species gives the total number of actual extinctions recorded since AD ; when CR PE and CR PEW species are also included, the resulting figure is an estimate of number of recent extinctions when uncertainty is taken into account.

Tables 3 and 4 are interactive. Each column can be ordered descending or ascending , and the numbers include links to search results on the website showing the lists of species represented in the tables. Tables 5 and 6 are organized by country. These should be used to see, for example, number of globally threatened mammals or the numbers of Critically Endangered species occurring within a specific country.

The figures presented in Tables 5 and 6 include only certain distributions, reintroduced species and regionally extinct species i. Important note : the figures presented in Tables 5 and 6 differ from the default setting for country searches on the website. The default search includes ALL occurrences within each country i. For wide-ranging marine species, country records are provided in assessments only where data are available for this. These records are also included in Tables 5 and 6. Tables 5 and 6 are interactive.

Table 5 - Number of threatened species Critically Endangered, Endangered and Vulnerable categories only in each major taxonomic group by country. Table 7 is organized by taxonomic group. This table should be used to check which species have changed Red List status since the previous Red List update and the main reason for the status change.

Table 7 is provided here for the current Red List and for previous Red Lists dating back to Important Note: Table 7 is provided only to summarize the reasons for species changing category between one Red List update and the next.

This table should not be used to calculate a Red List Index RLI ; for this it is necessary to analyse the underlying Red List data to identify genuine status changes between specific years for specific taxonomic groups. Note that in , Table 7 included species that were removed from the Red List for taxonomic reasons, and in Table 7 included genuine status changes only. Table 8 is similar to the country tables Tables 5 and 6 , but focus on endemic species only i. Endangered species are those plants and animals that have become so rare they are in danger of becoming extinct.

Threatened species are plants and animals that are likely to become endangered within the foreseeable future throughout all or a significant portion of its range. Species disappear because of changes to the earth that are caused either by nature or by the actions of people. Sometimes a natural event, like a volcano erupting, can kill an entire species. Other times, extinction will happen slowly as nature changes our world. For example, after the Ice Ages, when the glaciers melted and the earth became warmer, many species died because they could not live in a warmer climate.

Newer species that could survive in a warmer environment took their places. People can also cause the extinction of plants and animals.

The main reason that many species are endangered or threatened today is because people have. A habitat includes not only the other plants and animals in an area, but all of the things needed for the species' survival -- from sunlight and wind to food and shelter. The United States has many habitats, from ocean beaches to mountain tops. Every species requires a certain habitat in order to live. A cactus, for example, needs the sunny, dry desert in order to grow.

A polar bear, on the other hand, would not live in a desert, because it could not find enough food and water. Pollution can also affect wildlife and contribute to extinction. The Nashville crayfish is endangered mainly because the creek where it lives has been polluted by people. Pesticides and other chemicals can poison plants and animals if they are not used correctly.

The bald eagle is one bird that was harmed by pesticides. In the past, a pesticide called DDT was used by many farmers.

Rains washed the pesticide into the lakes and streams where it poisoned fish. After eating the poisoned fish, the eagles would lay eggs with very thin shells. These eggs were usually crushed before they could hatch. Today, people are not allowed to use DDT, and this has contributed to the bald eagle being removed from the endangered and threatened species lists needed for the species' survival -- from sunlight and wind to food and shelter.

How can we help: Eco Tourism The goal of wildlife conservation is to ensure the survival of these species, and to educate people on living sustainably with other species. The Foundations of Eco Tourism : tourism directed towards exotic, often threatened, natural environments, intended to support conservation efforts and observe wildlife.

Our responsibility to wildlife: Habitat destruction is the main threat to 85 percent of all threatened and endangered species, according to the International Union for Conservation of Nature.
