India has the most toxic air: Study

PRISCILLA JEBARAJ, The HINDU

It is official: India has the world's most toxic air.

In a study by Yale and Columbia Universities, India holds the very last rank among 132 nations in terms of air quality with regard to its effect on human health.

India scored a miniscule 3.73 out of a possible 100 points in the analysis, lagging far behind the next worst performer, Bangladesh, which scored 13.66. In fact, the entire South Asian region fares badly, with Nepal, Pakistan and China taking up the remaining spots in the bottom five of the rankings.

These rankings are part of a wider study to index the nations of the world in terms of their overall environmental performance. The Yale Center for Environmental Law and Policy and Columbia's Center for International Earth Science Information Network have brought out the Environment Performance Index rankings every two years since 2006.

In the overall rankings — which takes 22 policy indicators into account — India fared minimally better, but still stuck in the last ten ranks along with environmental laggards such as Iraq, Turkmenistan and Uzbekistan. At the other end of the scale, the European nations of Switzerland, Latvia and Norway captured the top slots in the index.

India's performance over the last two years was relatively good in sectors such as forests, fisheries, biodiversity and climate change. However, in the case of water — both in terms of the ecosystem effects to water resources and the human health effects of water quality — the Indian performance is very poor.

The Index report was presented at the World Economic Forum currently taking place in Davos, where it's being pitched as a means to identify the leaders and the laggards on energy and environmental challenges prior to the iconic Rio+20 summit on sustainable development to be held in Brazil this June.

Quality education still elusive (The Hindu Edit)

The key finding in a recent study that even top schools in major cities in India suffer from the entrenched tendency to impart rote learning may have some shock value to those who believe that private educational institutions place greater emphasis on quality and holistic education. However, for those closely observing the school education scenario, it is a re-affirmation of a bitter truth: schools in our country are, by and large, quite far from seeing education as a process of learning with understanding, acquiring knowledge through self-discovery and conceptualisation; rather, education remains a mere transmission of information in a rigid classroom atmosphere, where the emphasis is on memorisation and the objective is to rush through a pre-determined syllabus and prepare children for examinations. While on the scholastic side the WIPRO-Educational Initiatives 'Quality Education Study,' which covered 89 schools, shows a fall in learning standards among students in classes 4,...

Rooting For Home Essay by Mark Tully

In humans, as in plants, roots grow deeper if left to grow in one place, untransplanted MARK TULLY Magazine| Jan 12, 2009 T homas Hardy, who wrote some of the best known English novels, one of which was called The Return of the Native , said, "I am convinced that it is better for a writer to know a little bit of the world remarkably well than to know a great part of the world remarkably little." The bit of the world Hardy knew remarkably well was his native place, the county of Dorset in the west of England. It was a very small bit of the world, and a remote rural bit at that, which did not keep up with the fast-moving times of the last quarter of the 19th century. Hardy's novels reveal the profound influence of his native place but he was not a country bumpkin. One biographer of Hardy has said, "The two contrasting modes of feeling—for his native soil and for his cultural mecca (London)—entwine, sometimes fusing, sometimes pulling asunder, always with varying ...

How much you will charge to laugh?

Sonal Kalra, HT City, DDun My deepest sympathies to the family and friends of those who are always `dead' serious I give you three seconds to recall the last time you laughed out loud. One...two...three, done. All those who remembered the last `LOL' they'd casually typed while chatting on Facebook can take turns to slap each other. And the others, who at least tried to recall their real laughter but could not, listen to me. Kya, problem kya hai? Do people, who have to bear you every day of their lives, not deserve to sometimes see the twinkle in your eyes or the teeth that you claim to religiously brush every morning? Kya aapke toothpaste mein namak hai? Then what is the matter, people? Yesterday I observed this man at a friend's get-together. He was there to attend a party, but his face bore an expression as if the host had put a gun to his head and dragged him there. Someone told a joke, everyone laughed, even those who had heard it before. But this one's e...
