> Now we mostly fixed it Only in developed countries. The age of a typical car in my region is over 15 years. Basically, most of what you bought in 2005-2010, drove for a decade or more, and then sold for scrap eventually ends up in countries like mine. Moreover, most people take catalytic converters off their cars and sell them for $80-100 for platinum recycling. I think most "developing" countries have the same problem. So the world at large hasn't really solved it and won't solve it any time soon.
