I agree on all counts, Dave. Yes, there are environmental consequences to all industrial activity (this is hardly a secret). And, yes, the video's tone, as you so accurately say, is hysterical. The problem is that it comes off as an indictment, rather than a serious effort to solve any problems. It's also shot through with a lot of meaningless expressions ("a linear system can't work on a finite planet") that can't be challenged because they, in point of fact, make no sense. It seems to me there must be a way to get this point across in a balanced fashion that would make college students think logically about the issues, rather than react on an emotional basis.
@Chuck: While the statement "a linear system can't work on a finite planet" seems unnecessarily jargon-y, the point seems to be that since natural resources are limited, a process which leads from extraction to disposal (instead of recycling or reuse) will eventually use them up. This is clear enough; in fact, it borders on a tautology.
The problem, as you point out, is what to do about it. I think most people who have thought about it realize that many aspects of modern consumer society are not sustainable. On the other hand, most people also realize that a return to a small-scale agricultural or hunter-gatherer society is neither possible nor even remotely desirable. And, in fact, for the majority of the people in the world, the problem is not too much "stuff," but not enough "stuff" -- not enough clean drinking water, not enough sanitation, etc.
There aren't any easy answers to this, but you're absolutely right that, if we are going to find the answers, we need logical thinking and discussion, not just denunciation.
The 3D printing revolution seems to have a knack for quickly moving technology ahead by way of collaborative effort and even a little friendly competition -- all of course in the name of scientific advancement.
Advantech has launched a new series of motion-control I/O modules to meet the increased demands that come with more distributed industrial systems that require control of a growing number of axes and devices.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
