Today, there is not a single one left. What happened? The passenger pigeon became extinct. All living passenger pigeons disappeared from the earth entirely. The passenger pigeon became extinct for two reasons. First, the forests where it lived were cut down to make way for farms and cities. Second, many pigeons were shot for sport and because they were good to eat.
At that time, there were no hunting laws to protect endangered species like there are now. There are over 1, endangered or threatened species in the United States today. 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. Today, a small population of Javan rhinos is found in only one national park on the northern tip of the Indonesian island of Java.
A mainland subspecies of the Javan rhino was declared extinct in Vietnam in Javan rhinos are the most threatened of the five rhino species, with only around 60 individuals that live only in Ujung Kulon National Park in Java, Indonesia. The 10 most endangered animals: The Vaquita is a small harbor porpoise native to a very small area in the extreme northern part of the Gulf of California, Mexico.
It is the smallest known Cetacean whale, dolphin , or porpoise alive today, reaching lengths of only feet 1. Averaging cm or cm in length, it is the smallest of all living cetaceans. Today, the species is on the brink of extinction. The Vaquita is a small harbor porpoise native to a very small area in the extreme northern part of the Gulf of California, Mexico. Support Conservation Efforts The vaquita is just one species in peril.
Accidental entanglement in fishing nets is a major cause of unnecessary mortalities in countless species around the world. Support efforts to eliminate this threat! The 10 most endangered animals: For decades, mountain gorillas have been subjected to uncontrolled hunting, disease, habitat loss and the ravages of human conflict.
Their numbers plummeted, and they are now considered endangered. International Gorilla Conservation Program. Securing the Future for Mountain Gorillas. The International Gorilla Conservation Programme is a unique coalition of international conservation organizations …. Today, the tiger is classified as Endangered in the Red List of Threatened Species published by the International Union for Conservation of Nature IUCN and it is estimated that there are only 3, tigers remaining in the wild worldwide.
Wildlife Conservation Society. WCS Goals : Protect tigers and their habitat. Its population has declined by an estimated 50 percent over the past 75 years, and there are an estimated 20, to 40, Asian elephants left in the wild. The Asian elephant was listed as Endangered under the U.

Both species have experienced sharp population declines. A century ago there were probably more than , orangutans in total, but the Bornean orangutan is now estimated at about , based on updated geographic range Endangered and the Sumatran about 7, Critically Endangered. The destruction and degradation of the tropical rain forest, particularly lowland forest, in Borneo and Sumatra is the main reason orangutans are threatened with extinction.
Palm oil , an ingredient found in many everyday food and cosmetic products, is contributing to the rapid deforestation in Sumatra. Orangutan habitat in Sumatra and Borneo is being cleared at an alarming rate for conversion to oil palm plantations.
World Wildlife. Sumatran Orangutan Conservation Program establishing entirely new, genetically viable and self-sustaining wild populations of any great ape species, anywhere in the world. Leatherback turtles are named for their shell, which is leather -like rather than hard, like other turtles. They are the largest sea turtle species and also one of the most migratory, crossing both the Atlantic and Pacific Oceans.
Leatherbacks occur in the Atlantic, Pacific, and Indian Oceans. They occupy U. Pacific leatherback turtle nesting grounds are located in tropical latitudes in the eastern and western Pacific around the world. Extensive egg collection and bycatch in fishing gear are the primary causes of these declines. The Leatherback Trust. A non profit organization dedicated to saving the leatherback sea turtle by promoting conservation of leatherbacks at risk of extinction.
How many snow leopards are left in the wild? There are an estimated 4,, snow leopards in the wild, but it is difficult for scientists to know for sure.
Snow leopards live in the mountainous regions of central and southern Asia. In India, their geographical range encompasses a large part of the western Himalayas including the states of Jammu and Kashmir, Himachal Pradesh, Uttarakhand and Sikkim and Arunachal Pradesh in the eastern Himalayas. In the Himalayas, snow leopards live in high alpine areas, mostly above the tree line and up to 18, feet in elevation.
Snow Leopard Trust. Snow Leopard Conservancy. The Irrawaddy dolphin is a euryhaline species of oceanic dolphin, meaning they transition between saltwater and freshwater. They lack the characteristic beak and streamlined head of most dolphins, instead having a blunt snout and a high, rounded forehead.
The Mekong River Irrawaddy dolphins inhabit a mile stretch of the river between Cambodia and Lao PDR and are scarce—just 92 individuals are estimated to still exist. The dolphins are an important indicator of the health and sound management of the freshwater resources, and their decline could signal a potentially devastating decline in the health of the entire river ecosystem. The dolphins continue to die off at an alarming rate, and experts now estimate that there are only around 80 Irrawaddy dolphins left in the Mekong between Kratie and the Lao border.
The best place to see them is at Kampi, about 15km north of Kratie, on the road to Sambor Southeast Asia. Endangered Species International. ESI directly promotes sustainable fishing practices and no-fishing zones no-take zones in areas where dolphins are still found. Further, ESI focuses on restoring and protecting natural habitats like estuaries and rivers where dolphins occur.
Bluefin tuna populations have declined severely from overfishing and illegal fishing over the past few decades —not just Atlantic bluefin tuna, but also Pacific bluefin tuna and Southern bluefin tuna. Population declines have been largely driven by the demand for this fish in high end sushi markets. As the methods of catching tuna have advanced over the years, the conservation and management of tuna has not evolved as quickly.
Scientists believe that the collapse of bluefin tuna in the Mediterranean Sea may lead to a sharp increase in the biomass of bentopelagic cephalopods, such as squid. That much has always been true, and talking about recycling or creating a compost pile in their backyard is not a fun topic to broach for most.
That said, one of the things that have always motivated even the weak-hearted of conservationists is the idea that one day, there might not be any pandas left. Nor will there be elephants, polar bears, or sea turtles. People may not be scared about smog blotting out the sun, but they seem concerned as hell about baby tigers. Perhaps that is why people like Carole Baskin do what they do. The trick is motivation and in the case of organizations like the World Wildlife Fund, the best way to help is to donate.
Attending zoos is a small way to give back to these remarkable animals that have provided so much to our collective cultural heritage. Conservationists Criticize U.
