TIANJIN, Nov.23 (Xinhua)- Chinese scientists have signed a deal to establish a commercial animal cloning center in the northern port city of Tianjin, making the controversial science closer to mainstream acceptance.

The plant in the Tianjin Economic and Technological Development Area (TEDA), a government-sponsored business development park, will clone animals including sniffer and pet dogs, beef cattle and racehorses. Its main building is already under construction and due to be put to use in the near future, said a spokesman on Monday.

With an investment of 200 million yuan, the center will be jointly built by Sinica, Peking University’s Institute of Molecular Medicine, the Tianjin International Joint Academy of Biomedicine, and the Republic of Korea’s Sooam Biotech Research Foundation.

It will produce 100,000 cattle embryos a year initially, eventually increasing to 1 million, said Xu Xiaochun, board chairman of Boyalife Group, based in Wuxi. Chinese farmers are struggling to produce enough beef cattle to meet market demand, Xu said. The center, the largest ever worldwide, will also include a gene storage area and a museum, he added.

Scientists have cloned mice, cattle and other animals since the world’s first cloned sheep, Dolly, was born on July 5,1996 iii Britain. Since 2000, Chinese scientists have cloned sheep, cattle and pigs. China’s first commercial cloning company was established in September 2014 in Shandong with the birth of three pure-blooded Tibetan mastiff puppies.

Before this, cloning in China was limited to scientific research. More and more companies have shown interest in investing in the technology for commercial use, especially animal husbandry (饲养).

Four Wild Animal Species Were Endangered

Maybe you can still see them at the zoo. But that doesn’t mean they’re doing alright in the wild.

Tigers

All six tiger species are endangered, with Sumatran tigers and South Chin tigers at a seriously endangered status. The main reasons for their population decline are illegal hunting and destroyed habitats(栖息地), as humans clear forests to gather timber(木材)and build roadways. Only about 3890 tigers presently live in the wild.

Ground squirrels

That’s right, even squirrels are endangered, specifically the San Joaquin ground squirrel. Native to California, USA, these guys have been disappearing since 1979 on account of the construction and human developments going through their habitat. Their total population is unknown , but it could be anywhere between 124000 and 413000.

Giraffes

The International Union for the Conservation of Nature recently put giraffes at a vulnerable status, the level just before endangered. The giraffe population has declined 40 percent in the last 30 years, primarily due to loss of habitat and illegal hunting. Some giraffes are killed just for their tails, which are considered status symbols in Africa.

Asian elephants

The main threat to Asian elephants, one of the most intelligent animals, is their shrinking habitat. As the human population grows, people invade their land to build roads and railway tracks. Elephants in Myanmar are at an especially high risk for being captured and traded or used illegally in the tourist industry. Fewer than 50000 are left on the entire continent.
