The evidence for man-made climate change is quite compelling, and taking personal responsibility for your own impact on it isn't hard. I don't really see doing my washing at 6am as 'social and technological regression'. Quite the opposite actually - my washing machine has bluetooth and an app. I can tell it when to start.

The fact there isn't global pressure on corporations to be similarly responsible means my act of selflessness is ultimately a futile waste of time, but that's your kids and grandkids problem. I've chosen not to have kids, so I don't really care. I would suggest that choosing to have a family but not choosing to protect the environment as much as you can is an act of incredible selfishness towards your own children. They're the ones who'll have to live in a world with problems like water and food shortages. There is every chance that your grandchildren will die in a war over resources, and your view that tech is awesome will be little comfort to them.
