According to scientists, more than one and one-half million species exist on the earth today. However, recent estimates state that at least 20 times that many species inhabit the planet.
Each day about 100 species become extinct. Scientists estimate that the total number of species lost each year may reach 40,000 by the year 2000. This is a rate far exceeding any in the last 65 million years.
There are more than 3,500 protected areas in existence worldwide. These areas include parks, wildlife refuges and other reserves. They cover a total of nearly 2 million square miles (5 million square km), or 3% of our total land area. Today, the United States is the home of over 200 endangered animal species. There are more than 1,000 animal species
endangered worldwide.
Aquatic species, which are often overlooked, are facing serious trouble. One third of the United States’ fish species, two-thirds of its crayfish species, and almost three-quarters of its mussel species are in trouble.
Endangered Species Terms :
VULNERABLE - A species particularly at risk because of low or declining
numbers or small range, but not a threatened species.
THREATENED SPECIE – a species whose population is not yet low enough
to be in immediate danger of extinction, but who certainly faces serious problems. If the problems affecting these species aren’t resolved, it is probable that the species will become endangered. The eastern indigo snake and the red kangaroo are examples of threatened species.
ENDANGERED SPECIE – a specie, plant or animal, that is in immediate
danger of becoming extinct. Its numbers are usually low, and it needs protection in order to survive. The Siberian tiger, the southern sea otter, the snow leopard, the green pitcher plant, and thousands of other plants and animals are endangered worldwide.
EXTINCT SPECIE – an extinct species is one that is no longer living. The
passenger pigeon, the dodo, and the Stegosaurus are examples of extinct species. These animals no longer exist on the earth.
Answer:
Several species are being driven to extinction thanks, in large part, to human interference. Sometimes that interference is direct—poaching for big game trophies or animal tusks, and sometimes, it's indirect, such as when land is developed and disrupts habitats and entire ecosystems. Here are some of the incredible creatures we've driven to extinction in the last century and a half.
Bramble Cay Melomys
IAN BELL / WIKIMEDIA COMMONS
These little guys were officially declared extinct by the International Union for Conservation of Nature (IUCN) in 2015. Native to Bramble Cay, a small island near the northern side of the Great Barrier Reef, it's reported that the rodents haven't been spotted since way back in 2009. "Significantly, this probably represents the first recorded mammalian extinction due to anthropogenic climate change," said the Queensland state government.
Cause of Extinction: Man-made climate change which led to loss of habitat and food.
Yangtze River Dolphin
CHARLES HOY / WIKIMEDIA COMMONS
Also known as 'baiji,' the Yangtze River dolphin was last seen in 2002. Four years later, a group of researchers traversed 2,000 miles of the Yangtze River to see if they could find one but to no avail. According to the Whale and Dolphin Conservation group (WDC), the baiji is the first dolphin species to become extinct due to humans.
Cause of Extinction: overfishing, pollution, loss of habitat, poaching, and boat traffic.
The Northern White Rhinoceros

The last two living northern white rhino's in existence happen to both be female as the last male died in March of 2018. Sudan, the 45-year old male was under armed guard at Kenya's Ol Pejeta Conservancy when he passed away from old age and an infection.
The two females are also unable to give birth, making the likelihood of introducing a new generation of the species highly unlikely. Scientists are working on using harvested sex cells and IVF to bring forth a lab-created northern white rhino.
Cause of Extinction: poaching has decimated this population and loss of habitat also helped drive the rhino to the brink of extinction.
The Spix Macaw

Thought to be extinct in the wild, the Spix Macaw currently exists in captivity with their numbers in the dismally low 60-80 range. The bird is also referred to as Little Blue Macaw because they're known for their vibrant blue feathers.
Cause of Extinction: the Spix Macaw went extinct in the wild due to habitat destruction, illegal trapping and trade
UNIVERSAL HISTORY ARCHIVEGETTY IMAGES
The Thylacine, a carnivore also referred to as the Tasmanian tiger and Tasmanian wolf, was a (mostly) nocturnal marsupial that preyed on rodents and kangaroos.
Although Thylacine's looked fierce, they were actually quite timid and, according to Live Science, "could be captured without a fight." Reports of Thylacine sightings have been so frequent in the past century that it sparked an investigation as to the status of their existence.
Cause of Extinction: it is believed that Dingo populations threatened the Thylacine into extinction in addition to over-hunting from humans.
