Documentary

The accepted wisdom at the time, even from environmental scientists, was that all living organisms maybe apart from microorganisms were going to die out. However as seen from the documentary the flora has had a resurgence and previously endangered animals have returned to stable population levels, why do you think that is? (think about human interactions in the area and one of the previous questions you answered in this quizizz, there you will find your answer.)
