Top 15 Animals We Might Never See Anymore
Due to the different environmental problems and most especially human activities threatening their habitat, the existence of some species starts to decline.
Let us take a look at this list of animals close to extinction.
Javan rhinoceros is considered to be one of the most critically endangered animals with a total number of 60 animals from two populations. WWF has been involved in their protection and conservation since 1998.
Whooping cranes were very close to extinction in 1940s with only 16 left. However due to the efforts of innovative breeding programs, their number increases to over 400.
Unfortunately, there is at least 1,500 giant pandas in the wild. Its forest habitat in China has been fragmented, leaving pandas only 20 geographical areas to live. WWF has been working to help conserve giant pandas.
Sea otters are estimated 2,000 in number now, compared to 300,000 left in 1911. Sea otters are being hunted for commercial trade fur. They are also threatened by oil spills and killer whale predation.
Over the past ten years, the number of tigers decreased by 40 percent due to continuing deforestation and rampant poaching. Studies suggest that there are at least 3,200 tigers left in the world.
There are fewer than 6,500 snow leopards remaining in the wild. Poaching is the leading cause of their decrease in population, as well as the overhunting of their prey species.
Biologists estimate that there are at most 25,000 polar bears left in the world. Global warming affects their habitat, and if the warming continues, they may extinct within the next century.
There are at most 25,000 blue whales in the world. About 90% were reduced from their population in the 20th century. Water pollution, entanglement in fishing nets, ship collisions and climate change affect their existence.
Around 40,000 to 50,000 Asian elephants are left in the 13 countries they inhabit. The major causes of their population decline are poaching and lack of space and resources due to human overpopulation.
Orangutan or the “person of the forest” are less than 60,000 in population, as per a 2004 study. Major reasons of their critical endangerment is illegal logging and capture for exotic pet trade.
All species of gorillas are endangered. There are estimated 220,000 gorillas left in the wild. Habitat encroachment and poaching affect their existence. Gorillas also reproduce slowly, one birth every four years.
There ae only 250,000 walrus left in the world. Climate change also affects their habitat. Last September 2010, more than 200 walruses were spotted dead. Hunting also leads to their endangerment.
12 out of 17 penguin species are currently experiencing dramatic population decline. Change in the ocean current and temperatures due to climate change affected their existence. They are also threatened by oil spills.
Bluefin tuna is the source of your favorite sushi. Unsustainable fishing practices brought them near to extinction. WWF encourages restaurants and markets to stop serving and selling Bluefin tuna.
The population of monarch butterflies dropped due to the lack of primary food supply. Advanced agriculture has also affected their habitats.
