While I mostly agree, I would like to make one little point about "economic growth" not necessarily being worse for the planet: digital goods. People making money selling digital goods (e.g., downloadable songs/videos, subscriptions to internet content, etc.) doesn't have nearly the effect on the planet that making and shipping physical goods (VHS tapes, DVDs, CDs, magazines, etc.) does, especially as computing devices become more energy-efficient. So I think it is possible for the economy to grow in some ways without a negative ecological impact.
But yeah, people buying bigger cars (SUVs) and houses generally isn't good for the planet at all.
The ecological footprint of the internet and computers isn't nearly as much as all the carbon we pump into the atmosphere so we can drive around alone in 2-ton steel cages just so we can go buy little trinkets at various stores, frequently some distance from where we live.
