What this film points to is the only sustainable solution to climate change. It Marshall’s evidence that point out the fallacy of attempting to rely on hi tech solutions.. Rather, what needs to change is even tougher - it’s us that needs to change. It’s our incessant craving that is the problem. For a while now, I’m in the camp that we must reduce, as in, reduce-reuse-recycle. But, that’s not as sexy as a new shiny gadget.
