Its a 360 degree documantary. David does not only show us how in the last 60-70 years, by using our technology unintelligently, we have transformed this lively planet into a almost dead one, he also gives us the solution that are rather easy and interesting to follow.

As david rightly says that we are near extinction and its us who has to worry about it as the nature is capable enough to recover and rediscover itself, without us. We are not.
