The main reason why I downvoted this video is due to a different perspective. To my understanding, it tries to present a "field" of solutions that have been overlooked so far.
In a way, it assumes that we keep capitalism as it is. It assumes that all the polluters are honest about the numbers they make public on their pollution. It assumes that politicians are mainly looking to do public good and not that they are lobbied and funded by the big corporations. At least, that's how it sounds to me.
It does not talk about the systemic changes needed. We run on a model that has eternal growth as a fundamental thing. This is not sustainable by definition. Solutions need to address that, unfortunately this video doesn't.
