发帖数: 42116 | 1 India And China Both Struggle With Deadly Pollution -- But Only One Fights
It
India hasn’t yet seen state efforts of a scale that can revolutionize
pollution control (although this Diwali, India’s Supreme Court banned the
sale of fireworks in an effort to preserve air quality -- despite resistance
from Hindu religious groups and citizens alike). China on the other hand,
woke up to its pollution problem some years ago. According to analyses of
NASA satellite data, the levels of fine particulate matter got worse across
India by 13% between 2010 and 2015, while China’s fell by 17%. Delhi’s
average annual PM 2.5 concentrations are in the vicinity of 150 μg/m,
compared to about 60 μg/m for Beijing. Overall, Delhi’s PM 2.5 tends to
about three times the Beijing mean and 15 times the WHO guidelines. |
