Isn't that obvious?

Here's just a quick post from a link I found.
Did you know that traffic pollution can lead to a miscarriage? Yeah, I thought you did.

But this article is based on scientific fact with smarty-pants know-it-alls who spent lots of time and money figuring it out. Maybe, that's a little harsh.

One thing I did find interesting:

The study, which included 400 women having IVF treatment in Brazil, found that those who became pregnant in winter, when pollution levels are particularly high, were twice as likely to miscarry in the first eight weeks as those who conceived at other times of the year.

My main problem is that most miscarriages occur in the first eight weeks any time of the year. Sure, Morgan passed away at nine weeks, but that's close enough. And the study was based in fertility treatments of 400 women. Wouldn't you expect a little more info?
