As regular readers of my blog know, I had the pleasure of working in China for about five years. It was impossible not to be impressed by the rapid progress being made as the country modernized at breakneck speed. Every six months I would see huge changes in terms of new infrastructure, more traffic, and other signs of progress. Of course it was also impossible not to notice the negative impacts, particularly with regard to the environment. I worked in places such as Taiyuan where ‘blue sky days’ were an extremely rare event: all you had were smog laden skies.
