Model around consumption should get deeply revised if we want to leave the world in a good state for our children.

Refurbish rather than build new buildings

Build sturdy hardware with replaceable parts

Build from natural materials as much as possible, and invent a new concrete

Stop polluting by sprinkling deadly stuff to grow crops and make things

Develop recycling aggressively (98%)

Stop using oil derivates everywhere

Stop using nuclear fission as a power source

...

Problem is that it is antipodal with current economical growth models
