The country with the worst air pollution is not the one you’re thinking of
It’s a never-ending debate in Asia -- whose air quality is worse, China’s
or India’s? A new study by Greenpeace released Monday is trying to answer
that question.
Analysts looked at NASA satellite images and found that measurements of
particulate matter -- the microscopic particles that invade your lungs and
can cause cancer and heart disease -- improved impressively in China over
the past few years while air quality in India has worsened, with 2015
ranking as India’s most polluted year on record.
The satellite images showed that the levels of PM2.5 particles decreased by
17 percent in China from 2010 to 2015 and 15 percent in the United States
while rising 13 percent in India, the study found. |
