‘Revised WHO guidelines will put more pressure on govt. to combat pollution’
The stricter air quality standards issued by the World Health Organization (WHO) on Wednesday are a welcome move but it will be challenging for Delhi to achieve the new limits, experts and officials said.
“The new norms will put more pressure on the government to form policies to achieve stricter standards of air pollution. But achieving the new standards is going to be challenging,” said an official of the Delhi Pollution Control Committee.
The WHO, in the first update of its air quality guidelines in 15 years, has tightened global air pollution standards in recognition of emerging science that the impact of air pollution on health is much more serious than earlier envisaged.
When fed into Latin, pusilla comes out denoting “very small”. The Baillon’s crake can be missed in the field, when it is at a distance, as the magnification of the human eye is woefully short of what it takes to pick up this tiny creature. The other factor is the Baillon’s crake’s predisposition to present less of itself: it moves about furtively and slides into the reeds at the slightest suspicion of being noticed. But if you are keen on observing the Baillon’s crake or the ruddy breasted crake in the field, in Chennai, this would be the best time to put in efforts towards that end. These birds live amidst reeds, the bulrushes, which are likely to lose their density now as they would shrivel and go brown, leaving wide gaps, thereby reducing the cover for these tiddly birds to stay inscrutable.
