When China Family Panel Studies on 20,000 people across China between 2010 and 2014 compared the test results with the levels of nitrogen dioxide and sulphur dioxide pollution, they found a strong correlation that made them conclude that the longer the exposure to polluted air, the bigger the damage to the person’s cognitive abilities, specifically intelligence. Similar studies have pointed the same results in various countries. That means even if there is no end of the world happening as predicted by JWs, even the present situation would take us back to the same situation what you call as“a third or even a fourth world environment.”
