I disagree with this premise. Consumption by itself is not an issue, it's just a question of what we consume. For example, if all energy was generated from not-fossil-fuel, than (insofar as anthropogenic climate change is concerned) we have no climate-change problem at all. Pollution of any kind can be addressed in this way. Don't like electronic waste? Build electronics in ways that facilitate perfect recyclability. Don't like tire graveyards? Design tires that biodegrade, or are otherwise reusable. It's not that we need new technology to save ourselves. It's simply that we need to allocate resources towards moving our existing technologies in a more sustainable direction.
