Decline in Environmental Disaser Reporting

I've noticed within the past week or two there has either been a slight decline in environmental disasters or mainstream news is focusing on other things such as the Wall Street protests and other countries movements as well. This gets into the point that was talked about in class as to weather there are more disasters occurring or are news stations within a period where they don't need to report on the disasters cause they have "better" stories to keep people occupied with.
