A lot of the ideas are grandiose but doable, although I'd like to hear more about how he thinks synthetic organisms can possibly replace fossil fuels to support the energy demands of industrialized civilization. I don't buy it. I'd love to see the world's oil-based economy converted to a bio-economy, but as long as there's black gold spewing out of the ground I don't see it happening. And when the oil does run out, I don't see how any biological energy production system can support civilization as we currently know it. Remember the Roman Empire? That was probably the last serious bio-economy of human history. How much better can we do?
Anyway have a watch and see if you can come up with better ideas for saving civilization.
