evidence: KS: In short, yes, but I think Groucho makes a very important point. It is correctly diagnosing the problem. If we fail to study and adequately diagnose the problem, we can apply the wrong solution. It happens all the time. But I do think that the work, the effort, the motives of this Earth System Treaty are a worthy ambition to attempt to rally people across the world’s cultures. As I said, the development of the UN Sustainable Development Goals has been extraordinary. With these efforts by the world community to identify the causes behind these global-scale problems and also identify potential solutions for getting us out of these problems, I think we’re on the right track. I am not as pessimistic as Groucho Marx was. I do think that humans have an extraordinary intellectual capability and can move resources and create more opportunities so that we can reach a sustainable, peaceful world.
