Hahaha, you joke, but I so wish that we could clean all of the air worldwide.
People started a class action lawsuit about getting sick from the mines close to them and they won the case.
Another evil is the old powerstations that burn tons of coal and I look forward to the day that they don't exist anymore.
South Africa is now very active in the natural electricity generation fields, such as wind farms and Solar energy. Let's hope that it continues to grow.
Cheers and thanks!
