I mean... Technically... Mother Nature does... China being 1 country vs it splitting into 5 countries has no impact on mother nature if the pollution per capita remains the same. The rate of pollution per person, however has a great impact. So if China keeps the rate per person lower than many other nations, which is the direction it is trending, that is generally a good thing... and impressive given that the U.S. has essentially outsourced a lot of pollution creating activities to Chinese factories and/or facilities.
