I watched a very interesting documentary last night on CBC about the effects of environmental toxins on humans. It sounds as though humans are on a dangerous path to extinction, with a marked decline in male birth rates and an increase in reproductive problems in males. I highly recommend watching this documentary (you can view it online)! The run time is about 44 minutes.
You can view the entire documentary at the CBC website (viewable in Canada only)
You can also watch it on Google's video site if you are not in Canada
This is absolutely worth watching. I'd love to hear your comments if you do watch it.
