Sounds like you have stirred a lot of ideas into a pot, Ake, some of which are good and others of which will not bear close inspection.

Capitalism is not the single thing which ruined the planet by any means. Organizing human effort in order to undertake large projects is not inherently evil--termites and ants do it and are not blamed. THe problem is large-scale projects and industries with unknown side-effects.

I completely agree that compassionate technology needs to replace the more hostile sorts of technology currently in use. That is a small idea but a huge undertaking.

As for "completely destroying the planet", I think you will find that is not the case. We definitely are harming the thin shell of the ecosphere and having an impact on the climate, but the planet is of a different scale and it will do just fine long after we are relocated elsewhere.
