Five years ago I learned about China's Cancer villages, and it has never left the "featured" list on this blog since. It is a terrifying, and moving report. But what I didn't know was that Deng Fei, a Chinese journalist, published a map of these cancer villages in China. Today, English-readers have a translated version of that map available to explore here:

If you zoom in and select specific villages, there is even a short description of their specific situation on the left.
Eg: (found at G106 / the southernmost point on the mainland)
"name
This visual had brought something to my attention that may or may not be relevant, that all the listed villages fall within the Eastern half of China.
Why? To be honest I don't know. Maybe that is the "only" ground Deng Fei could cover. All the same, I'd want to thank him for bringing this to the world's attention because evidently what he did has started steps to clean things up.
