First of the nature episodes is nicely done, as it takes a look at the potential threat of Africanized killer bees, who may make their way into Western Civilization, cutting a swath of terror in their wake. The biology of bees and their regimented society is examined, as is the origin of how they came to threaten humans. Only nitpick with this episode is of course how that killer bee invasion date of 1990 came and went with nothing happening that I know of! That is the trouble with giving specific future dates of course, but this entry is still reasonably effective to succeed, even if there has been nothing in the news lately about them...
