Big city life may change residents' green outlook: study

People, especially with good jobs, living in large cities are more likely to engage in green activities, says a new study based on the world's fastest growing economy, China's environmental behaviour.

The study, the first to weigh employment and leadership while considering environmental behaviour, showed that the downsides of China's explosive urbanisation such as pollution and greenhouse gas emissions now are joined by an upside -- better environmental citizens.

The findings, published in the journal Environmental Conservation, showed that the city size -- especially the good jobs there -- influences citizens' pro-environment behaviours, like recycling plastic bags and sorting their trash.

"It is essential to study human behaviour because it directly affects the environment," said study author Jianguo "Jack" Liu, director of the Centre for Systems Integration and Sustainability at Michigan State University.

"As China is the world's fastest growing economy and cities are the economic engines with severe environmental challenges, understanding environmental behaviour of urban residents in China is particularly important," said Liu.

China, which surpassed Japan as the world's second-largest economy last year, is also the biggest polluter in the world.

For the study, researchers used China's General Social Survey of 2003, in which some 5,000 urban people were asked specifically about their environmental behaviour.

The study conducted jointly by the Hong Kong University of Science and Technology and the Renmin University of China found that it was the behaviour that ultimately counts to conservationists.

People who live in larger cities like Beijing, Shanghai and Tianjin showed significantly more of this green behaviour than people in smaller cities, the study found.

But, study co-author Xiaodong Chen emphasised that it's about employment -- not money -- a finding that flies in the face of some traditional thought that pegged green attitudes as a luxury of the fiscally comfortable.

"You don't have to be rich to consider environmental issues," said Chen. "Even if people are poor and their material needs are not as well met, they still consider the environmental quality because those people may be threatened more by environmental problems."

The workplace seems to be a strong leader in environmental education, a dynamic that may be particularly powerful in China, which has a tradition of policies and regulations being shaped from the top down.

Employers, with their accompanying status and political power, are also proving to be powerful drivers of conservation and those workers who are workplace leaders report the most environmentally friendly behaviour, the study found.

Chen said companies in big cities have more resources to promote environmental initiatives, such as education. He also said people who live in the largest cities are more widely exposed to media reports about the environment.

"Facebook Tests a New Feature To Let Users Enjoy Events Togather"

Facebook is testing a new feature to let users share events that they are interesting in attending to, on their "Stories" so that they can coordinate with friends and enjoy events together.

The test is currently rolling out to users in the US, Mexico and Brazil.

To use the new test feature, go to the Events page, click "Share" below the date and time of the eve…

India can produce 2,500 MW power from waste: Study

Energy deficient India can produce 2,500 MW electricity by 2012 by recycling millions of tonnes of municipal and industrial waste generated each year, an Assocham study has said. About 40,000 million tonnes of solid waste and 5,000 million cubic metre of liquid waste is generated every year in the urban areas which can be suitably recycled, it said."Expedite setting up of waste energy projects as there is potential of generating 2,500 MW of power from urban, municipal and industrial wastes in large cities to partly meet energy shortages," it said.

The study estimates that about 1,500 MW of power could be generated from urban and municipal wastes by setting up waste energy projects and additional 1,000 MW from industrial wastes in the country by 2012.Assocham has suggested that funds required -- around Rs 200 crore -- could be generated through municipalities and local governments.It further that India has potential to reduce its projected emissions over next 30 years by near…

Largest Spike in Hate Crimes Since 9/11, Says a Report

The number of hate crimes reported in the United States jumped by 17% last year, the largest increase since 2001 when the terrorist hijackings on 9/11 fueled a surge in attacks on Americans of Muslim and Arab ancestry.

A total of 7,175 hate crime incidents were reported to the Uniform Crime Reporting (UCR) Program in 2017, up from 6,121 in 2016, said the UCR Program's annual Hate Crime Statistics report, Xinhua reported.

It's the third year in a row the FBI has reported an increase in hate crimes. The number of hate crimes in 2016 rose about five percent from 2015.

The 2017 incidents encompass 8,437 total offences, meaning some involved multiple criminal charges.

According to the report, the most common bias categories in single-bias incidents were race/ethnicity/ancestry (59.6 percent), religion (20.6 percent), and sexual orientation (15.8 percent).

The victims represented a cross section of society, with African-Americans and Jews the most frequently targeted victims. Of 34…
