Explanation / Answer

1)

The Thylacine is a large carnivorous marsupial now believed to be extinct. It is also known as the Tasmanian Tiger or Tasmanian Wolf.

The Thylacine was sandy yellowish-brown to grey in colour and had 15 to 20 distinct dark stripes across the back from shoulders to tail. Although the large head was dog- or wolf-like, the tail was stiff and the legs were relatively short. Body hair was dense, short and soft, to 15mm in length. The female Thylacine had a back-opening pouch

Thylacines preferred kangaroos and other marsupials, small rodents and birds. The Thylacine hunted singly or in pairs and mainly at night.

At one time the Thylacine was widespread over continental Australia, extending north to New Guinea and south to Tasmania. The species was best known from the north and east coast and midland plains region rather than from the mountains of the south-west.

The Thylacine became extinct on the Australian mainland not less than 2000 years ago. Its decline and extinction in Tasmania was probably hastened by the introduction of dogs, but appears mainly due to direct human persecution as an alleged pest

2) Extinction of Thylacine was depended on the human . With the introducing of the dogs as there pets he humans in australia saw thylacine as threat and started killing them

Another animal which is going to extinct because of the human behaviour is The Pangolin , The pangolin is a small, scaly anteater found in Africa that looks like a walking pine cone. They are traded on the black market for food and their scales are used in sham medicine in China and Vietnam.They are the most illegaly traded animal

The northern rock mountain Grey wolf , Gray wolves once dominated the western landscape, but widespread killing virtually wiped them out . The primary threat to wolves in the Northern Rockies is overly aggressive state management that caters to anti-wolf sentiment fueled by myth and misinformation and now it is succefully proctected by successful reintroduction program in central Idaho and Yellowstone National Park

3) The passenger pegeon or the wild pegeon was mainly used for transporting of letter and valuable information by kings to the respected person . The reason behind the extinction of passenger pegeon was hunters

Thousands of hunters would then jump on newly built trains to ride out to wherever the pigeons had settled and start slaughtering them. The hunters weren't just killing the birds to feed their families, however. Pigeons would be stuffed into barrels and loaded back onto the trains, which would deliver them to distant cities, where they'd be sold everywhere from open air markets to fine restaurants. Martha, the last of her kind who died at age of 29 years

4) For the past 400 years, humans have been the leading cause of animal extinctions -- humans are responsible for approximately 75 percent of the extinctions during this period The common characteristic are

4) A “biological annihilation” of wildlife in recent decades means a sixth mass extinction in Earth’s history is under way and is more severe than previously feared . Scientists analysed both common and rare species and found billions of regional or local populations have been lost. They blame human overpopulation and overconsumption for the crisis and warn that it threatens the survival of human civilisation, with just a short window of time in which to act.The climate change is  poised to become a major threat in the coming decades.

These process cause destruction to not only animals but also plants thus reducinng the oxygen level in earth and the food for survival which inturn leads to crisis among humans and thus extinction of human race
