The change in economic values created by the new markets for global public goods will reorient our global economy and under the right conditions can usher the satisfaction of basic needs of the present and of the future. This is what is needed right now.

CO2 from air can replace petroleum: it can produce plastics and acetate, it can produce carbon fibers that replace metals and clean hydrocarbons, such as synthetic gasoline. We can use CO2 to desalinate water, enhance the production of vegetables and fruit in greenhouses, carbonate our beverages and produce biofertilizers that enhance the productivity of the soil without poisoning it. Carbon negative technology is absolutely needed now.

The new markets that arise from ecological constraints will dominate the 21st century economy, and so will markets for knowledge.

Changing an economic system that is bent on uncontrolled and poorly measured economic growth and depends on fossil energy for its main objectives, is much more difficult than changing how nuclear energy is used for military purposes. Some think it may be impossible.

If nuclear warfare is believed to be somewhat controlled, then climate change is now the greatest threat.

After denial comes anger and finally, acceptance.

We need a transformation of the world economy and of how we use and share the Earth's resources. We are running out of time. We are truly at the point of no return.
