What does the latest 5-year plan say about the number of rivers to be poisoned? For here one is dealing with a major popular initiative to fulfill, then overfulfill, and to do it faster than originally planned.
yeah, it is quite possible that their 5-year plan included the construction of a gazillion Benzene-producing chemical plants.
As a result, Chicom could produce enough Benzene to kill entire Chinese population ten-times over. Ultimate population control, I guess.
