Study: Tree-lined streets have significantly cleaner air.

I posted last week about the pros and cons of exercising in polluted air , and touched very briefly on the importance of choosing routes/locations that minimize your exposure. For example, river-side bike paths are great, because pollution drops exponentially as you move away from roadways, and trees can help block the bad air.
