massive scale manufacturing will never be "sustainable" or "green",(reply>), @Paul S is it impossible to have the notion of industry without the notion of profit?,(reply>), Which is why ICE engines should be run into the ground before being replaced.,(reply>), @Paul S With climate regulation and limits of carbon, profit won't be the only factor. With renewable technology and energy prices rising it already makes sense for large scale manufacturers to make their own renewable energy sources on site.,(reply>), @trevor Wilkinson hence industry cannot go green. profit trumps ecosense,(reply>), I disagree, it's mainly that massive scale manufacturing is about cutting costs to a minimum, and currently that is not green. I think it would be perfectly possibly to scale green manufacturing technologies, but at the moment it doesn't make economical sense.
