Summary:
Scientists have long recognized that tropical rainforests are home to the greatest biodiversity on Earth. However, Terry Erwin's study of forest canopies was surprising; he concluded that there were up to twice as many different species in the tropical forests than previously estimated! His research led to the suggestion that as much as 90-95% of the word's organisms dwell in tree tops, and about 90% of those are insects. In this episode of Environment and Ecology, students venture into the forests to learn about its awe-inspiring cornucopia of life forms!
