Blood samples from white yaks in a herding village in Gansu province revealed as many as 28.77% are infected with Chlamydia Abortus, potentially threatening a vital source of income for locals.
Chlamydia Abortus is a strain of the STD that commonly infects humans which greatly increases the risk of fetus deaths in mammals. It is transmitted sexually or orally, found in various species including humans.
Zhuaxixiulong village, one of two locations tested, had the highest prevalence in their herds, with more than a quarter of the white yaks infected. The overall average was 16.22%.
Vetrinary universities from Jilin, Hunan and Anhui collected samples from 974 of the rare yaks in Zhuaxixiulong village and Xidatan village, Tianzhu Tibetan Autonomous County, Gansu Province between 2013 and 2014.
The number of blood samples with positive results was slightly less than the black yaks tested in neighboring Qinghai province (17.66%) and significantly lower than tests from India, where herds showed results as high as 35%.
Milk, meat and leather from the white yak are an important commodity to those in the county, which has around 40,000 white yaks in total. In some areas, it is considered a holy entity and worshipped by the locals.
Green advertising grows 50% in China, though many guilty of “Sin of No Proof”
As pollution continues to draw criticism, advertising for green products and services has seen huge growth in the last decade.
Between 2004 and 2014, green advertisements in newspapers and magazines increased by 49%, according to a study by Huazhong University’s School of Management in Wuhan, China.
Defining green advertising as containing messages that promote planet preservation, animal preservation or personal health preservation, researchers examined more than 1,300 green ads in prominent newspapers and magazines.
They found Chinese companies tended to focus on selling green products while foreign-owned enterprises were more likely to gear their ads toward developing a green brand.
With almost nothing in the way of laws or regulations to restrict them, 33% of Chinese companies were found guilty of greenwashing – spinning a product as green, even if it’s not. The most common example found were advertisements with the ‘sin of no proof’, where advertisements makes claims they cannot back up.
In 2011, China’s State Administration for Industry and Commerce, identified more than 230,000 false advertisements were published daily, with only 16,000 being dealt with due to lack of resources.
Oil, chemical and plastics companies were the most prominent green advertisers based on industry, with transport equipment manufacturing and household appliances coming in second and third respectively.
Among the Chinese ads, 69% focused on product sales, with the remaining 30% examining corporate branding. For foriegn enterprises the numbers were more moderate with 56% of advertisements for green products.
“These numbers show that enterprises in China were more motivated by product sale than corporate image when deploying green advertising, while foreign enterprises adopted a more balanced strategy,” the study, titled “A Content Analysis of Green Advertising in China”, said.
It was published in the Journal of Marketing and Case studies at the end of 2014.
