US reduction in carbon emissions prevented that, while nations like China and India increased 10 fold. Wow America was great, contrary to the naysayers!
You are badly mis-informed.
If you live in the one of the top 10 (or even 20) most polluted urban areas, air pollution is an issue you have to contend with every day. Here are the concentration levels for the 10 most polluted urban areas in the world today:
1 – Pakistan: 115.7
2 – Qatar: 92.4
3 – Afghanistan: 86
4 – Bangladesh: 83.3
5 – Egypt: 73
6 – UAE: 64
7 – Mongolia: 61.8
8 – India: 60.6
9 – Bahrain: 56.1
10 – Nepal: 50
China, despite numerous reports in recent years about its air pollution being at extremely high levels, manages to miss the top 10 most polluted urban areas and comes in at number 13 with an average PM 2.5 of 41.4. In fact, China has been making a concerted effort to improve air quality levels throughout its major cities. Bloomberg News recently reported China Is Winning Its War on Air Pollution, at Least in Beijing. This is a good sign and shows hope for the people in other heavily polluted cities and countries around the town.
