"A change in thinking about what underpins the world we live in needs to occur on a large scale."
As a first cut, meaning, limiting the focus of what I have said, here is a link for you guys to skim and think about.
I'd like you to carry this in your mind as a microcosm of a much larger interacting dynamical system we can call 'the world'. As my understanding of the problems we are facing grows I hope to be able to post my thoughts on how people are attempting to grapple with these problems. Obviously, some of you can grasp these topics much more clearly than I can. However, that is of no value unless real work takes place in the understanding of our mission as humans. We must survive. As far as is known, in the universe, we are the most intelligent form of life. SETI has mapped most of the sky and there are no signals.
Technological civilization only gets one shot at making it. The reason is technological civilization consumes everything available to advance. Remember the aliens in the movie
Independence Day? They is us. I don't mean to frighten you but I do mean to shock some of you awake to the reality of what is happening.
I will state again the problem, finite resources limit consumption. All the money in the world will not solve the problem of resource allocation. The purpose in providing the link to a fish study is to acquaint you with how a population uses things in its environment to sustain its survival. And that is what we are talking about here, not paying some bills and saving a little money for retirement. We are talking about the future and whether we can sustain ourselves in a world of dwindling resources.
