Thank you for that extremely thoughtful post Apricity.
This phrase rings home "I do everything in my own small way to change this at a personal and household level, with public activism and actively supporting organisations trying to bring about changes etc." both for what my Australian family do and what we do here.
It is not for the will to do more that things do not get done. My (Australian) DiL's degree was in the environment field and has she also worked in relevant departments in the Universities over there. I also find you have, at the grass routes level of families, more information about what can be done by individuals which she happily passes on to me. But this is not enough, as you say.
It is for governments to lead the way. There is no market driver, certainly as yet, which will lead us out of the industrialisation we have grown used to. The right, unless they see money in it, will not do this in my opinion. My opinion of them, as you may be aware, is very low.
I was pleased the Labour Party over here put forward the Green Industrial Revolution as a way forward. It wasn't the Green New Deal but I felt people could see it as a way of maintaining their standard of living - which the right seem to value more than life - and move forward helping other countries to do likewise. I see nothing coming from this government, which was voted in using some of the same people in this country who aided and abetted the PM in Australia to his current position by, as they do here, appealing to the basest instincts of the population.
