But a great many—at first hundreds, then thousands, and finally perhaps millions—find themselves marooned. Extinction rates soar, and the texture of life changes. Never miss a story!

Premium Why is the Madhya Pradesh government replacing eggs wit Premium Why the draft health data management policy raises red A critical situation that affects a few populations around the Congo river: Rwanda, Uganda and Congo.
The causes? The disappearance of its habitat caused by l ogging companies and, most of all, once again, poaching. More than park guards have been murdered in the National Park of Virunga, where most of these animals live, an indication of the struggle for their preservation. It dies due to elevated salinity in the water, the short life span of offspring, contamination in the area and the methods used to fish the recently famous panga fish.
In , only 85 of these animals could be found. Hunting and sale as pets and the large palm oil industries are the reasons for its critical situation.
These consider the orangutan as an enemy of their crops and kill them without pity. Indonesia has lost more than half the surface of its tropical forest in the last 50 years to favor these plantations. These ape can only be found in Borneo and Sumatra.
A species of sea turtle that is in serious danger of extinction along with the leatherback turtle. Although they increasingly attract tourism, accidental fishing, water contamination and hunting for their shells, meat or eggs has nearly decimated these animals. After million years on the planet, they may not survive the effect of humans.
Human actions keep harming the biodiversity of Earth, so we add five animals in this ranking of endangered species. This extension confirms the abuse of man of the rest of the plane t and underlines the urgent need for protection campaigns for all species, especially the endangered ones.
It is perhaps the most iconic image of the effects of climate change. Their habitat has been seriously threatened for several decades by the melting of the Arctic pole, causing the isolation of the species , more difficulty in getting food and sometimes distances too long to swim. The general rise in global temperatures is causing the critical situation of this kind of native penguins in southern Argentina.
The fish that inhabit the icy waters of Antarctica are emigrating because of warming of ocean currents. These fish are eaten by penguins, who are forced to travel hundreds of kilometers to find new food, trips in which many die.
One of the most iconic species in Africa such as the giraffe is a recent addition to this sad list. At present there are less than one hundred thousand specimens. Two main factors are threatening the jaguar, and both are motivated by human action. First, the jaguars are hunted for their fur, a prized trophy. It is also the enemy of farmers, who expand their territories near jaguars and often defend their flock killing the potential predators. The situation of this kind of wolf is more than critical.
Forty years ago, in the mids, it was declared an endangered species. He further said that extinction is happening faster now than ever before and there are some species which are left in such few numbers that the next generations may not be able to see them if nothing is done for their conservation. Here are some of the endangered species, the extinction of which will affect the humans badly in the years to come. From millions, the population of the Indian Vulture has reduced to just a little over 10, The cause of this decline has been identified as poaching, habitat destruction and kidney failure by poisoning caused by the pesticides and veterinary drug diclofenac which the Vultures swallow with flesh of dead cattle.
Raghunandan said that the decline of Indian Vultures can affect the health of the environment and humans drastically. In their absence, the population of scavengers like wild dogs and rats, along with their zoonotic diseases would increase greatly, he said. Another species under threat that humans rely on is the Bumble Bees.
Bumble bees face many threats, including habitat loss, pesticides, diseases and climate change. While Bumble Bees do not produce as much honey as Honey Bees, they are effective pollinators for a large number of plants and agricultural crops, said Mr. The declining population of pollinators like Bumble Bees is a direct concern for human health as it would disrupt pollination that is essential for fruits and vegetable production and would negatively impact food security for the mankind.
Rhinoceros, the large herbivorous mammals that had a population of over 5 lakh at the beginning of the 20th century are now survived by only 27, individuals globally, as per WWF. Three species of rhino- black, Javan, and Sumatran are critically endangered. Due to its medicinal properties, the horns of rhinos are in high demand, thus, poaching is a major threat to their survival.
Apart from poaching, habitat loss is another cause of the loss of these species. Existence of Rhinoceros matters to humans as they share habitat with a large variety of plants and other animal species and so they help in protecting the ecosystem which provides oxygen, food and other services essential for the human survival.
According to IUCN, since , tiger population has dropped from around 1 lakh to an estimated 3, Poaching, habitat loss and human-wildlife conflicts are the main reasons for the decline of their population.
According to Mr. Raghunandan, tigers are extremely important in maintaining a healthy ecosystem which helps in a healthy survival of human beings. He said that protecting tigers does not just benefit them but also conserve other co-habituating species.
Tigers play a pivotal role in the health and diversity of an ecosystem being a top predator at the apex of the food chain. Tigers keep the population of wild animals in check, thereby maintaining the balance between prey herbivores and the vegetation upon which they feed and so if the tiger go extinct, the entire system would collapse, says WWF. As per the Ministry, there are about 1 lakh Dugongs globally and only in India.
It was added to IUCN list in as vulnerable to extinction. The major threat to Dugongs is the degradation of seagrass habitat, poaching for their meat, oil, hides, bones and teeth, pollution, water transport traffic and fishing. The presence of thriving population of Dugongs indicates healthy Seagrass Habitat in the marine system. According to Waterman of India, Dr. Rajendra Singh, seagrass has the capacity to capture carbon from the atmosphere and thus help in combating climate change.
Seagrass grows more and in better quality because of the constant trimming done by Dugongs as they eat it. Over the last years, human activities have made Sea Turtles vulnerable to extinction, according to WWF. The Sea Turtles face threat from poaching which is done for their eggs, meat, skin and shells, in addition, habitat destruction, plastic pollution in oceans, accidental entangling in fishing nets also known as bycatch and trash on the beaches also cause their deaths.
