忘了长城 – 我们现在有大的雾度
“Forget the Great Wall – We Now Have the Great Haze”
– Translation by Google
In the 1960’s and 1970’s astronauts showed that we could see the Great Wall of China from space. Today, it’s the Great Haze of China that we can see from space . The New York Daily News, here, published this image, taken by NASA in January 12, 2013 (here) when the Air Quality Index, AQI, reached 775.
The AQI was established by the US EPA. AQI above 300 is considered dangerous. AQI at 775 is probably deadly.
