The series is reasonable for information presentation to those who would otherwise be completely ignorant, however, when actually listening to what is said by the narrator, there are holes aplenty with many assertions made with completely incorrect reasoning, e.g. "plastic is not biodegradable BECAUSE it is manmade"
- It being manmade is very much not the reason for this inherently, nor is it a true statement given the immediately preceding statement about bacteria being able to break it down in days
This is just one example, but it is rife throughout the series
There is also a significant undercurrent of political agenda that is very difficult to ignore, detracting from the "101" nature of the presented information
