Lets fight Global Warming

Here's a piece of news which should inspire other nations... Germany is set to ban cars which cause excessive air pollution from running in city centres and central places. There would be labels on the cars which show the amount of damage they do... from light to excessive and based on that it'll be decided as to whether cars would be allowed to run or not. Initially, this policy is to be implemented in Berlin, Cologne and one other city... in due course, it will be implemented in other cities too. Thumbs up to Germany for that!
